Problem with building an Android build of my unity2D project

Question

I am a beginner game developer and I want to upload my game to unity. Unfortunately, when I try to build my project in unity as an Android build, it gives me a few errors. Here is the first error:

"CommandInvokationFailure: Gradle build failed.

C:\Program Files\Unity\Hub\Editor\2020.2.2f1\Editor\Data\PlaybackEngines\AndroidPlayer\OpenJDK\bin\java.exe -classpath "C:\Program Files\Unity\Hub\Editor\2020.2.2f1\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\gradle\lib\gradle-launcher-5.6.4.jar" org.gradle.launcher.GradleMain "-Dorg.gradle.jvmargs=-Xmx4096m" "bundleRelease"

stderr[

Please file a bug against the Java compiler via the Java bug reporting page (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com) for duplicates. Include your program and the following diagnostic in your report. Thank you.

and here is the second:

It will be removed in a future version of the Android Gradle plugin, and will no longer allow you to disable R8.

Can anyone help me on these errors?

Answer 1

Hi Aidan. I have actually encountered this same issue in Unity before! You might have the issue resolved already, but this might help in case someone has a similar problem.

I went digging through my project history and found this post, which I was able to use to fix the issue:

https://stackoverflow.com/questions/69776130/how-to-fix-gradle-build-failed-on-unity

What ended up helping me here is the first answer which instructs to remove the android.enableR8 line from your gradleTemplate.properties file. If that doesn't work, I would suggest considering updating your version of Unity since it is quite old. Just remember to have a backup or some sort of version control since a migration from one Unity version to another could be project-breaking.

If you'd like, feel free to message me here on Wyzant to schedule a lesson and we can work together to solve your problem! Good luck with your build!

Answer 2

I haven't built anything with Unity, but I figured I'd try a Google search for you, and found this StackOverflow discussion: https://stackoverflow.com/questions/68344424/unrecognized-attribute-name-module-class-com-sun-tools-javac-util-sharednametab

I could have just searched StackOverflow directly. I knew it would most likely be where I'd end up. It's a great source of information for these sorts of issues, and it's a great skill to develop to learn how to search it (and the web generally) for programming issues and to learn how to sort through the results (some responses are old, are not highly voted, etc.). It's community driven, and it works! You can even post your own questions there. Or maybe even become an answer contributor.

From glancing at some of the suggestions there, it sound like fiddling with your jdk version might help (though I don't know how that's set for Unity or for Unity Android builds).

Good luck! You can schedule a session with me to fiddle with it together, but I really don't have any actual experience with Unity, so it _would_ be more fiddling than knowledge-based tutoring/direction.
