native linux package

Did you manage not just run test under linuxX64 target with Gradle but also make distributive package for Linux, that works natively without JDK installed? Is it possible at the moment?

Newest version is not posted on repository

Hi, can you please provide the newest 0.6.0 version on some repo? Please be advised, that the jcenter is deprecated. It would be a shame if you stopped working on such great software :) keep up the good work.

How to download engine libraries?
I am looking for a 3D library in Java or Kotlin and your one looks very promising, so I want to try it out. Working through the QuickStart (https://github.com/zeganstyl/thelema-engine/wiki/Quick-Start), lots of classes cannot be imported. Probably I need the engine as stated in the Main page from readme (https://thelema.app/), where you write: Enter your credentials to download engine libraries. How to get token.

I have created a token in GitHub, but when I try a gradle build, I am still getting Could not GET 'https://maven.pkg.github.com/zeganstyl/thelema-engine/app/thelema/thelema-jvm/0.7.0/thelema-jvm-0.7.0.pom'. Received status code 401 from server: Unauthorized

My build.gradle.kts looks as follows (inserted username/token instead of ... parts):

[...] repositories { jcenter() mavenCentral() maven { url = uri("https://maven.pkg.github.com/zeganstyl/thelema-engine") // not found credentials { username = "...myusername..." password = "...thetoken..." } } } dependencies { implementation("app.thelema:thelema-jvm:0.7.0") // this is the current version implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8") implementation("org.ksdfv.thelema:thelema-lwjgl3:0.1.0") testImplementation(kotlin("test")) } [...]

How can I download the engine files? Do you need to give access? (I noticed that you are also in GitLab, I can also access there if you prefer that).

Thanks a lot!

Old links, and overall deprecated "quick start"

Hi, links are no longer valid in your doc. For example here: https://github.com/zeganstyl/thelema-engine/wiki/Postprocessing-shaders Links there lead to 404 error. Please update the links. Also can you please add some contact info to you? (mail, facebook)
