Flutter failed for task app:mergeDebugNativeLibs and app:mergeDebugJavaResource

Question

FAILURE: Build completed with 2 failures.

1: Task failed with an exception.

• What went wrong: Execution failed for task \':app:mergeDebugNativeLibs\'.

Answer 1

I had the same issue after setting up my flutter project to run on iOS. When I tried to run it back on Android, this error was thrown.

This worked for me (on Windows):

1. Close your project and close your code editor

2. Open Task Manager

3. Finish all vscode-related tasks you see (or related to the IDE you are using)

4. Finish all Java-related tasks, inclidung OpenJDK Platform binary (there are usually two of these; finish both)

5. Go to your project's root folder and delete the build folder

6. Open your project again and run

Good luck!
