Question Error during "Build Gradle Project"

I am still struggling with my Android build and now I get an error during the "Build Gradle Project". I have been trying to google, testing etc. but have not been able to understand how to solve this annoying problem.

Here is the error I get:

* What went wrong:

Execution failed for task ':unityLibrary:compileReleaseJavaWithJavac'.

> Compilation failed; see the compiler error output for details.


* Try:

Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.


Details:

Code (CSharp):

1. Picked up JAVA_TOOL_OPTIONS: -Dfile.encoding=UTF-8
2. An exception has occurred in the compiler (1.8.0-adoptopenjdk). 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.

33.  

 

I updated to latest version of Unity and it worked for this project, have problems with my next project.

 

Have same problem, i try to build any project and taking this issue. Unity version 2018.4.36f1. Building another project on Unity 2019.4.29f is going fine. BTW my teammate compiling same projects on another machine with no problems. What do i do wrong? i make JDK SDK and the other **K from UNITY or from official sources.

 

After updating Unity I have no problems with this anymore.

 

I resolving this problem for myself too, but a different way.

In Android Studio -> Settings -> SDK Tools, Downgrade sdk version from last (in my case 31) to 30, same for sdk build tools, and then it works great for me

 

this worked for me but the problem is that I already used the same environement to build a game with zero errors, and now I am working on a new project and this error poped up :/

 

I can't update Unity past 2018 and I'm having this issue too

 

As mentioned, try downgrading from SDK 31 to 30 and it should solve the issue.
Share what you tried so that can help you out.

If you are not finding a way to downgrade, you can try this
1. Open Unity's android sdk installed folder
2. Delete platforms/android-31 and build-tools/30.1.x folders
3. Restart Unity
5. Set Target API in Player Settings to either API 30 or Automatic (Max Installed)

 

Targeting 30 instead of 31 works but that's not what I was trying to do. I wanted to build for 31

 

I followed the instructions here: https://developers.google.com/ar/develop/unity-arf/android-12-build

This fixed the issue for me.

 

Update: As we need to target >= API 31

Old - Deprecated
You can even try this. Most likely this will work too and avoid touching the custom gradle files.
1. Go to Unity's Android SDK folder -> build-tools
2. Delete any with 31.x.x
3. If you see 30.x.x build tools already, you are done here.
4. If you don't see 30.x.x build tools, just copy it from build-tools folder of Android sdk installed through Studio (this will be usually the default android sdk path).

 

In my case - the error turned out to be using an old version of Android Gradle Plugin (3.6.4) after update Unity to v2020.3.33 (also as 2021.3.0).

In one of the updates Unity - updated and version of Gradle, which was not compatible with the old version of the plugin.

Solution

• No need JDK 11 (use by default 1.8)
  
• Download Android 12 (API 31) - Unity automatically uses it as a Target API (Android 12L (API 32) is also possible - doesn't really matter)
• Set Android Gradle Plugin version to 4.0.1 in the file baseProjectTemplate.gradle
  
  Code (CSharp):

  1. classpath 'com.android.tools.build:gradle:4.0.1'
• Android Build Tools leave version 30.0.+ (as with 31 and above - so far incompatible with Unity)

 

As mentioned by @leni8ec We see this solution is better as we can avoid upgrading to Java 11.
Once you set the android gradle version to 4.0.1, you may see some errors but eventually it can be fixed with a custom gradle plugin version in external tools

 

Try to set Target API to 30 (Downgrade it).

 

Same issue here, on Unity 2019.4.40f1, downgrading from SDK 33 to SDK 30 solved it.

 

Setting Gradle version to 4.0.1 in baseProjectTemplate.gradle fixed the problem for me.

 

For those who struggle to build using Unity 2019 and need Android SDK 31 (Google Play requires it).

1. First install latest LTS version (at this point it is 2019.4.40f1)
2. Download gradle v 6.1.1 (yes, because below that you get an error when trying to set 4.0.1 in baseProjectTemplate as mentioned above), latest 7+ version is not good neither.
   
3. Target Android API 31 (you might need to install SDK from CMD or just launch Unity Editor as Admin and it will install SDK automatically).

 

Was running into similar problem. Turns out it's specific to Android SDK 32. Tried with Android SDK 33 and everything built fine.
