A Gradle Plugin that removes unused resources in Android projects.

I am migrating my project to use Multi-project structure.

My project structure

-root
    -Project1 
    -build.gradle
    -Project2 
    -build.gradle
        -Subproject1
        -build.gradle
        -Subproject2
        -build.gradle
        -Subproject3
        -build.gradle

I have written a task clean in my subproject(Subproject1/build.gradle). I want to delete the folder build in Subproject2 and Subproject3.

But I am getting below exception message.

FAILURE: Build failed with an exception.

* Where:
Build file 'D:\User\workspace\root\Project2\Subproject1\build.gradle' line: 12

* What went wrong:
A problem occurred evaluating project ':Project2:Subproject1'.
> Declaring custom 'clean' task when using the standard Gradle lifecycle plugins is not allowed.

Can you please suggest me how to fix this issue and reason for this error message?

Hi, i'd like to install on my Ubuntu machine.

1. clone repo
2. inside lint-cleaner-plugin folder i write in terminal './gradle install

in build.gradle i put

buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:0.12.2' classpath 'com.droidtitan:lint-cleaner-plugin:0.1.0' } }

allprojects { repositories { jcenter() } }

it doesn't work.

Can you help you?

Does it make sense to have the plugin run by default when building an Android project? Should the user instead have to manually run "gradle lintClean" in commandline. I find that I only clean projects every couple of weeks and not after every build.

Silent failure of the final file move on Windows was causing problems.

Now move failures will be reported, and the move in general is more robust and succeeds where it previously failed.

In the case where the move does fail, the temp file is deleted, other wise it leaves the project in an unbuild-able state.

app/build/outputs/lint-results.xml is not a lint xml file

BUILD SUCCESSFUL

Total time: 38.773 secs

This build could be faster, please consider using the Gradle Daemon: https://docs.gradle.org/2.10/userguide/gradle_daemon.html

build.gradle 文件内容： `// Top-level build file where you can add configuration options common to all sub-projects/modules. apply plugin: 'android' apply plugin: 'com.droidtitan.lintcleaner' buildscript { repositories { jcenter() mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:2.1.3' classpath 'com.droidtitan:lint-cleaner-plugin:0.3.0'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}

}

allprojects { repositories { jcenter() } }

task clean(type: Delete) { delete rootProject.buildDir } ` 输入命令： gradle lintClean 报错信息： Declaring custom 'clean' task when using the standard Gradle lifecycle plugins is not allowed.

It didn't remove the unused drawable file(.xml), but modify it and make compile failed. After run gradle lintClean, the xml resource files would be like below: anim:

<?xml version="1.0" encoding="utf-8"?>
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1"
    android:fromXDelta="0%"
    android:fromYDelta="0%"
    android:toXDelta="0%"
    android:toYDelta="0%"
    />

selector:

<?xml version="1.0" encoding="utf-8"?>
    <item android:drawable="@drawable/btn_border_blue_normal" android:state_checked="true"/>
    <item android:drawable="@drawable/round_white"/>
</selector>

style:

<resources>

    <style name="AppTheme" parent="android:Theme.Holo.Light.DarkActionBar">
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:textColor">@color/text_default</item>
        <item name="android:textColorHint">@color/text_grey_light</item>
        <item name="android:actionBarStyle">@style/CustomActionBar</item>
        <item name="android:windowBackground">@null</item>
        <item name="android:activityOpenEnterAnimation">@anim/activity_open_enter</item>
        <item name="android:activityOpenExitAnimation">@anim/activity_open_exit</item>
        <item name="android:activityCloseEnterAnimation">@anim/activity_close_enter</item>
        <item name="android:activityCloseExitAnimation">@anim/activity_close_exit</item>
    </style>

    <!--EmptyView的样式-->
        <item name="android:layout_width">wrap_content</item>
        <item name="android:layout_height">wrap_content</item>

        <item name="android:textColor">@color/text_grey_light</item>
        <item name="android:paddingBottom">@dimen/height_common</item>

    </style>

Signed-off-by: Desert zyallday@gmail.com Hi， marcoRS I recently found that this plugin would destroy drawables which write by xml. I checked the source code,and I found when a xml-drawable is unused the tag location is like this:

<location file="path/to/file" line="3" column="2">

then it will be added into the filePathToLines, so I fixed it
