Minify WithR8 throws java.lang.OutOfMemoryError: Java heap space

Question

I'm facing a problem when trying to compile my app from command line using following command:

./Project/gradlew -b ./Project/sampleapp/build.gradle assembleProd -x lint --stacktrace

But command throws follwing error:

Caused by: com.android.tools.r8.CompilationFailedException: Compilation failed to complete

I've tried many solutions that I found in stackoverflow, here and here, but none of them has worked.

Changed gradle.properties:

org.gradle.jvmargs=-Xms4096m -Xmx8192m -XX:MaxPermSize=2048m -XX:+HeapDumpOnOutOfMemoryError

Changed gradlew file to add JAVA_OPTS and GRADLE_OPTS:

DEFAULT_JVM_OPTS="-Xms4096m -Xmx8192m"
JAVA_OPTS="-Xms4096m -Xmx8192m"
GRADLE_OPTS="-Xms4096m -Xmx8192m"

Changed zshrc:

export JAVA_OPTS="-Xms4096m -Xmx8192m"
export GRADLE_OPTS="-Xms4096m -Xmx8192m"

Added dexOptions javaMaxHeapSize to build.gradle:

    dexOptions {
        javaMaxHeapSize "8g"
    }

Nothing worked :( I'm using a MacOs 11.6.2 with 16GB RAM

I don't know what to try anymore.

The problem was solved puting the org.gradle.jvmargs=-Xms4096m -Xmx8192m -XX:MaxPermSize=2048m -XX:+HeapDumpOnOutOfMemoryError configuration in the global gradle.properties file, found in ~/.gradle/gradle.properties and not only in the project properties.
