Windows PC, building in Unity 2020.1.0f1 to Android
After updating to the latest version of Unity, I am no longer able to build any project to Android, though building to other platforms works perfectly.
I’ve tried reinstalling all of the Android related external tools (JDK, Android SDK and Android NDK), but was unable to delete some files as they were in use by openJDK. I think there is a ghost instance of OpenJDK running in the background blocking access to Gradle files, but I can’t end this instance through task manager, as it doesn’t show up in any sub-processes or background processes.
this is the debug output I’m receiving :
FAILURE: Build failed with an exception.
- What went wrong:
Could not create service of type FileAccessTimeJournal using GradleUserHomeScopeServices.createFileAccessTimeJournal().
Timeout waiting to lock journal cache (C:\Users\Mikolaj.gradle\caches\journal-1). It is currently in use by another Gradle instance.
Owner PID: 9680
