A gradle plugin for getting java lambda support in java 6, 7 and android

Overview

Gradle Retrolambda Plugin

Maven Central

This plugin will automatically build your java or android project with retrolambda, giving you lambda goodness on java 6 or 7. It relies on the wonderful retrolambda by Esko Luontola.

Note: The minimum android gradle plugin is 1.5.0 and the minimum gradle plugin is 2.5.

Usage

  1. Download jdk8 and set it as your default.

  2. Add the following to your build.gradle

    buildscript {
       repositories {
          mavenCentral()
       }
    
       dependencies {
          classpath 'me.tatarka:gradle-retrolambda:3.7.1'
       }
    }
    
    // Required because retrolambda is on maven central
    repositories {
       mavenCentral()
    }
    
    apply plugin: 'com.android.application' //or apply plugin: 'java'
    apply plugin: 'me.tatarka.retrolambda'

    alternatively, you can use the new plugin syntax for gradle 2.1+

    plugins {
       id "me.tatarka.retrolambda" version "3.7.1"
    }
  3. There is no step three!

The plugin will compile the source code with java8 and then replace the class files with the output of retrolambda.

Configuration

You can add a block like the following to configure the plugin:

retrolambda {
  javaVersion JavaVersion.VERSION_1_6
  jvmArgs '-arg1', '-arg2'
  defaultMethods false
  incremental true
}
  • javaVersion Set the java version to compile to. The default is 6. Only 5, 6 or 7 are accepted.
  • include 'Debug', 'Release' Sets which sets/variants to run through retrolambda. The default is all of them.
  • exclude 'Test' Sets which sets/variants to not run through retrolambda. Only one of either include or exclude should be defined.
  • jvmArgs Add additional jvm args when running retrolambda.
  • defaultMethods Turn on default and static methods in interfaces support. Note: due to a limitation in retrolamba, this will set incremental to false. The default is false.
  • incremental Setting this to false forces all of your class files to be run through retrolambda instead of only the ones that have changed. The default is true.

Using a Different Version of the retrolambda.jar

The default version of retrolambda used is 'net.orfjackal.retrolambda:retrolambda:2.5.6'. If you want to use a different one, you can configure it in your dependencies.

dependencies {
  // Latest one on maven central
  retrolambdaConfig 'net.orfjackal.retrolambda:retrolambda:+'
  // Or a local version
  // retrolambdaConfig files('libs/retrolambda.jar')
}

Deprecated Features

If you are running with java 6 or 7 you should really consider updating. However, you may use the below configuration instead.

Set the environment variable JAVA8_HOME to point to the java 8 jdk. Alternatively, you can set the jdk property.

retrolambda {
  jdk System.getenv("JAVA8_HOME")
}

You can force unit tests to be run with an older version of java by setting JAVA5_HOME/JAVA6_HOME/JAVA7_HOME or with the oldJdk property.

retrolambda {
  oldJdk System.getenv("JAVA6_HOME")
}

Android Studio Setup

Add these lines to your build.gradle to inform the IDE of the language level.

android {
  compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
  }
}

Proguard

This plugin is fully compatible with proguard (since v2.4.0). In your proguard file, add

-dontwarn java.lang.invoke.*
-dontwarn **$$Lambda$*

Known Issues

Lint fails on java files that have lambdas.

First try updating to the latest version of the android gradle plugin. Newer versions of lint are compatible with java 8 sources. If you can't for some reason, you can still use the experimental fork to fix the issue.

Using Google Play Services causes retrolambda to fail

Version 5.0.77 contains bytecode that is incompatible with retrolambda. This should be fixed in newer versions of play services, if you can update, that should be the preferred solution. To work around this issue, you can either use an earlier version like 4.4.52 or add -noverify to the jvm args. See orfjackal/retrolambda#25 for more information.

retrolambda {
  jvmArgs '-noverify'
}

  • Support the new Transform API

    Support the new Transform API

    Starting with 1.4.0-beta2, the android gradle plugin includes a Transform API to manipulate class files. This should be a better way to do things as it's guarenteed to play well with other tasks unlike the current implementation.

  • Retrolambda breaks lint

    Retrolambda breaks lint

    Related to #69, but figured I'd open a more general issue for discussion and the hope that someone has come up with a creative solution to this.

    As of right now, the version of Lombok used by the linter doesn't support lambdas, which causes it to fall over during linting (example output below). This is a dealbreaker for many, as lint is an important tool for catching issues and can also double back as a data generator for scripting tools (like removing unused resources).

    An ideal solution would probably be a recompiled version of the linter with an updated Lombok dependency that supports Java 8.

    A possible alternative could be adding a rule to somehow skip LambdaExpression nodes in the AST during processing, though I think this would come at the expense of knowing anything inside the lambda.

    Example output of the exception encountered:

  • Issue compiling from clean build

    Issue compiling from clean build

    I've started running into an issue with retrolambda and the latest AppCompat release.

    Steps to reproduce:

    1. Update AppCompat dependency on a project to 22.1.1
    2. Run ./gradlew clean
    3. Run ./gradlew compile (Yes, separately from the last step - done together it worked sometimes)
    4. See this error if you are using lambdas inside of a class extending FragmentActivity:

    The strangest part is that doing a non-clean build will work, though I suspect that's because it's skipping the retrolambda step.

    This happens with retrolambda 2.0.0 or 2.0.2 (I tried both).

    These are not static method calls.

    apt generated directory not found.

    gradle-retrolambda version 2.4.1 / android-apt 1.4 / android gradle (0.14.1) / tools 21.1.0

    Suddenly we are seeing strange issues in our build process.. there are no diffs to any gradle files.

    However, we now see this:

    :models:patchAndroidJar
    :models:_compileReleaseJava
    javac: directory not found: 
    /projects/android/models/build/generated/source/apt/release
    

    and this is the order of applied plugins:

    apply plugin: 'com.android.library'
    apply plugin: 'retrolambda'
    apply plugin: 'android-apt'
    

    Everything was working fine a few hours ago.. and checking out source to yesterday doesn't seem to help. Is anyone else noticing bizarre issues today? Or am I completely nuts? I'm at a bit of a loss at the moment.

    Just to verify my java8 installation, I created a gradle project in intellij without retrolambda, and that works fine.

    Do you have any idea, what might go wrong here and how to fix it?

  • Unused resources when used in Lambda expressions

    Unused resources when used in Lambda expressions

    I have stumbled upon an issue while using retrolambda + Android + lint. Lint verification tool fails on finding strings referenced from string resources when that string is used in same place as a lambda expression. Simple example can be:

    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    builder.setMessage(R.string.message)
        .setPositiveButton(R.string.close, (dialog, which) -> {
            switch (which) {
                case DialogInterface.BUTTON_POSITIVE:
                    dialog.dismiss();
                    break;
            }   
        }).show();
    

    This when running ./gradlew lint will cause R.string.close produce a lint warning: The resource R.string.close appears to be unused and in my case fail the build. I could of course ignore that by using tools:ignore or pass Resources fetched String from outside the method call wherever I am using lambda expressions but that doesn't seem the right way. Code should be readable and short, this is the target of lambda expressions as well, so adding code to satisfy lint because of retrolambda seems like going against that principle. For instance this doesn't produce any warnings after adding String string = getString(R.string.close) and referencing it in AlertDialog.Builder.setPositiveButton(...):

    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    String string = getString(R.string.close);
    builder.setMessage(getString(R.string.message, body.getError().getData()))
        .setPositiveButton(string, (dialog, which) -> {
            switch (which) {
                case DialogInterface.BUTTON_POSITIVE:
                    dialog.dismiss();
                    break;
            }   
        }).show();

    :app:preRobolectricDebugUnitTestBuild UP-TO-DATE

    An exception has occurred in the compiler (1.8.0_45). Please file a bug at the Java Developer Connection (http://java.sun.com/webapps/bugreport)  after checking the Bug Parade for duplicates. Include your program and the following diagnostic in your report.  Thank you.

    robolectric is flavor with robolectric tests.

    Looks like it's related to #23.

    I can file an issue on b.android.com if it's problem of Android Gradle Plugin.

When I applied this plugin, it was found the lambda code in the project is converted , but the code in the library seems not. Is there any configuration to set so the plugin can change the byte code of the aar/jar files?

    NoSuchMethodError?

    i was trying add an flutter module(which request host app java1.8 compile compileOptions { sourceCompatibility 1.8 targetCompatibility 1.8 }) to an existing app(which has to stay in java 1.7 because of butternife and someother pluginin) so i apply plugin me.tatarka:gradle-retrolambda:3.6.1 to the host app. it will compile correct. but in runtime app crash because NoSuchMethodError like:

    07-11 11:57:52.630 6726 6726 E AndroidRuntime: java.lang.NoSuchMethodError: No direct method lambda$initAccountView$2(Landroid/view/View;)V in class Lcom/meituan/epasspo rt/core/controller/extra/DefaultPagerAdapter; or its super classes (declaration of 'com.meituan.epassport.core.controller.extra.DefaultPagerAdapter' appears in /data/app/c om.sankuai.meituan.meituanwaimaibusiness-WyCD2GxSv5brl1ZkqBQvmw==/base.apk!classes3.dex)

    i try more find the crash caused by a library use me.tatarka:gradle-retrolambda:2.3.4. plugin to compile lamda in java 1.7 so what happened here? why different versions of me.tatarka:gradle-retrolambda(3.6.1 in app, 2.3.4 in library) cause crashs? and how could i avoid this runtime crashs(it is dangerous bacause i have no idea how many libraries of my host app use plugin me.tatarka:gradle-retrolambda)?

  • Can I use retrolambda after end of 2019?

    Can I use retrolambda after end of 2019?

    Whenever enter into Android Studio, I got follow warning message

    WARNING: API 'variant.getJavaCompile()' is obsolete and has been replaced with 'variant.getJavaCompileProvider()'. It will be removed at the end of 2019. For more information, see https://d.android.com/r/tools/task-configuration-avoidance. REASON: It is currently called from the following trace: java.lang.Thread.getStackTrace(Thread.java:1556) com.android.build.gradle.internal.errors.DeprecationReporterImpl.reportDeprecatedApi(DeprecationReporterImpl.kt:79) com.android.build.gradle.internal.api.BaseVariantImpl.getJavaCompile(BaseVariantImpl.java:423) com.android.build.gradle.internal.api.TestVariantImpl_Decorated.getJavaCompile(null:-1) me.tatarka.RetrolambdaPluginAndroid.configureCompileJavaTask(RetrolambdaPluginAndroid.groovy:106) me.tatarka.RetrolambdaPluginAndroid.access$3(RetrolambdaPluginAndroid.groovy:-1) me.tatarka.RetrolambdaPluginAndroid$_apply_closure2.doCall(RetrolambdaPluginAndroid.groovy:53)

    This means getJavaCompile will removed but retrolambda use this. Is there any release plan for this?

    Source code(zip)
  • v3.2.1(May 1, 2017)

  • v3.2.0(May 1, 2017)

    • Support for targeting java 5 with retrolambda.
    • Don't depend on the android gradle plugin being on the classpath when using in pure java projects.
    • Delay calculating classpath for retrolambda. This fixes missing aar libs added by the android gradle plugin.
    Source code(tar.gz)
    Source code(zip)
  • v3.1.0(May 1, 2017)

    • Major refactoring of android plugin. The method for modifying the javaCompile task is now way less hackey. In fact, it is much closer to the original way that it was done. I had originally abandoned this approach because it was breaking increment compilation is some weird ways. However, I think I have solved it.

    What this means for you: It is now less fickle of plugin application order and way less likely to break other plugins.

    • Properly split bootclasspath if it has multiple paths
    Source code(tar.gz)
    Source code(zip)
  • v3.0.1(May 1, 2017)

    • Fixed occasional "Build exception: cannot call Task.setEnabled(boolean)" error.
    • Fixed minor warning typo.
    • Uploaded to the gradle plugin portal.
    Source code(tar.gz)
    Source code(zip)
  • v3.0.0(May 1, 2017)

    A whole bunch of changes!

    • Changed the default retrolambda to 2.0.0
    • Added support for default methods, add defaultMethods true to the retrolambda block. Note: due to a current limitation in retrolamba, this will require all of your class files to be fed through retrolambda on each build. This may adversely affect build times.
    • incremental false is no longer deprecated but has different semantics. Instead of being a hack around gradle-retrolambda breaking other plugins, it now only forces all of your class files to be run through retrolambda instead of only the changed ones.
    • Added support for android unit tests, including lambdas in the tests themselves.
    • No longer patch the android jar, modify the classpath instead. This should resolve issues with using gradle-retrolambda with more obscure android sdks, like google glass. This should also speed up a clean build since it doesn't have to do any zipping shenanigans.
    • Ensure the gradle plugin is compiled with java 6 compatibility. This should allow you to run gradle with an older version of java if you don't want java 8 set as the default. This was always the intention, but was broken in the last build.
    • More minor changes to how the java compile task is replaced, this should ensure better compatibility with other plugins. Note: these changes make the plugin application order more important. Make sure you you apply this plugin last.
    • Removed 'retrolambda', now you can only apply the plugin with 'me.tatarka.retrolambda'.
    Source code(tar.gz)
    Source code(zip)
  • v2.5.0(May 1, 2017)

    • A more robust fix for android-apt compatibility. Important: If you were experiencing issues with android-apt previously and updated to this version, you must run gradle build --rerun-tasks once.
    • Deprecate plugin name 'retrolambda' for 'me.tatarka.retrolambda' in preparation to publishing on the gradle plugin portal.
    Source code(tar.gz)
    Source code(zip)
  • v2.4.1(May 1, 2017)

    • Fixed compatibility with android-apt.
    • Fixed typo in one of the thrown exceptions. (tomxor)
    • Support groovy testing (ex. spock). (harningt)
    Source code(tar.gz)
    Source code(zip)
  • v2.4.0(May 1, 2017)

    • Better incremental compile method that doesn't break lint and proguard (and probably other tasks). Because of this, retrolambda.incremental is deprecated and does nothing.
    • Better handling of manually setting the retrolamba version with retrolambConfig.
    • Don't use the retrolambda javaagent if using version 1.6.0+.
    • Set the default retrolambda version to 1.6.0.
    Source code(tar.gz)
    Source code(zip)
  • v2.3.1(May 1, 2017)

  • v2.3.0(May 1, 2017)

    • Add ability to set retrolambda.incremental false to disable incremental compilation, since it is incompatible with android lint/proguard.
    Source code(tar.gz)
    Source code(zip)
  • v2.2.3(May 1, 2017)

  • v2.2.2(May 1, 2017)

    • Support a java.home path that does not end in /jre, by using it as it is. This is an issue on OSX which may have a different directory structure.
    Source code(tar.gz)
    Source code(zip)
  • v2.2.1(May 1, 2017)

    • Ensure output directory is created even if the source set is missing files for the java plugin. Otherwise, compiling the source set would error out.
    Source code(tar.gz)
    Source code(zip)
  • v2.2.0(May 1, 2017)

    • Added way to add custom jvm arguments when running retrolambda.
    • Disable extractAnnotations tasks since they are incompatible with java 8 sources.
    Source code(tar.gz)
    Source code(zip)
  • v2.1.0(May 1, 2017)

    • Also check system property 'java.home' for the current java location. IDEs set this but not JAVA_HOME, so checking here first is more robust. (aphexcx)
