[LibGDX] Access JAR bundled resources during runtime.

[metaphore]

Hi @Tom-Ski,
Not sure entirely how to cover this problem in a form of an issue, so I guess this format suits it better.
In short, I have troubles delivering asset files bundled inside the library's JAR to a LibGDX iOS submodule.

The same case is trivial for all other backend submodules. After adding the library's jar as a Gradle dependency, I can simply read the resources with either one of Gdx.files.runtime(), Gdx.files.internal() or Gdx.files.classpath(), because the project's asset files are streamlined into the distribution archive. But it's not the case for MobiVM backend, where only the locally placed and declared in build.gradle/robovm.xml resource files make it to the output IPA.

The question is there anything I can do to automate the asset inclusion for the library end-users, so they don't require any extra iOS configuration steps in order to integrate the library?

hi,
MobiVM backend does include resources in .jar files by stripping class files and including these .jars under libs folder in iOS application bundle.
Could you please check if these are there and resources are present as well ?

Sorry for the late reply. I still have difficulties building for iOS target on my M1 mac, so needed help on the side to validate the issue.

Here is the project https://github.com/metaphore/mobivm-transient-resource-issue-showcase

It declares both gdx-vfx dependencies in the core module

dependencies {
    ...
    api "com.crashinvaders.vfx:gdx-vfx-core:$gdxVfxCoreVersion"
    api "com.crashinvaders.vfx:gdx-vfx-effects:$gdxVfxEffectsVersion"
}

The vfx-effects lib contains a collection of important asset files (mostly .frag/.vert shader files) defined as resources as it may be seen here. And they are reported as missing when the app is launched on iOS device/simulator.

It seems like only the content of vfx-core lib makes it to the iOS build. Here's how the Payload/IOSLauncher.app/lib of the output IPA file looks like. I know they are just manifest containers, but still strange that the vfx-effects is missing here.
