unityLibrary:mergeReleaseJavaResource Task failure when making an Android with LevelPlay dependencies

Adamska_01 · July 27, 2024, 5:58pm

Hi, I am trying to integrate LevelPlay in my project (I followed this video for the setup: https://www.youtube.com/watch?v=sU5njx1jn8w&t=495s). I went through all the necessary steps and setup IronSource with 2 networks: UnityAds and Google AdMob. I am not 100% sure of this, but I believe the build worked before adding GooleAdMob, but now I get this error:

Java seems to spit out a lot of unnecessary garbage, but I think the more relevant errors are the following:

What I have tried:

Setting the target API Level to 32, 33, 34, and 35
Setting custom main gradle template (This seems to automatically delete all Android dependencies that the dependency resolver installs, which seems wrong, but the error is still there)
Running a “force resolve” with the Android dependency resolver tool
Adding “android.useAndroidX=true” and “android.enableJetifier=true” to the gradleTemplate
Setting a more up-to-date gradle installation in the Preferences->External Tools (particularly “gradle-7.6.3” and “gradle-8.9”

I am on Unity 2022.3.7f1.
If anyone came across this, Please do let me know how to fix it🙏

Hi,

What worked for me was to add:

packagingOptions {
               resources.pickFirsts.add('META-INF/kotlinx_coroutines_core.version')
        **PACKAGING_OPTIONS**}

to :
-the Main Gradle Template ( just after aaptOptions {…} )
-the Launcher Gradle Template ( just after buildTypes {…})

So here’s what my Main Gradle Tempate looks like:

// Android Resolver Repos Start
([rootProject] + (rootProject.subprojects as List)).each {
    ext {
        it.setProperty("android.useAndroidX", true)
        it.setProperty("android.enableJetifier", true)
    }
}
([rootProject] + (rootProject.subprojects as List)).each { project ->
    project.repositories {
        def unityProjectPath = $/file:///**DIR_UNITYPROJECT**/$.replace("\\", "/")
        maven {
            url "https://maven.google.com"
        }
        maven {

        }
        maven {

        }
        mavenLocal()
        jcenter()
        mavenCentral()
    }
}
// Android Resolver Repos End
apply plugin: 'com.android.library'

I hope that helps!

That worked for some reason . I just don’t understand how the whole “dependencies” thing works. If I add a custom Main gradle template, all the Android dependencies installed by the Android resolver are deleted (and once they are deleted, the build keeps failing again). Does it mean that I need to manually add them to the template?

Do you mean something like in that topic (which I made yesterday when I had the same problem) happens?

I posted the solution in it
