I met a similar error:

CommandInvokationFailure: Gradle build failed.
/Applications/Unity/PlaybackEngines/AndroidPlayer/Tools/OpenJDK/MacOS/bin/java -classpath "/Applications/Unity/PlaybackEngines/AndroidPlayer/Tools/gradle/lib/gradle-launcher-4.6.jar" org.gradle.launcher.GradleMain "-Dorg.gradle.jvmargs=-Xmx4096m" "assembleRelease"

stderr[
D8: Program type already present: bitter.jnibridge.JNIBridge

FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':transformDexArchiveWithExternalLibsDexMergerForRelease'.

I copy the plugin folder only into asset folder, then I can success. Do not copy the androidwrapper folder.
