So today I’ve installed the new Android Studio (3.4) which comes with new Gradle and Gradle plug-in versions. As in the past most of my projects got broken and needed some tweaking in order to be able to build.
The only unresolvable problem is with my Safenetwork project that uses the gradle-java-flavours pluging. It fails with:
Could not get unknown property 'classesDir' for mock local test classes of type org.gradle.api.internal.tasks.DefaultSourceSetOutput.
classesDir is deprecated and removed and
SourceSetOutput.getClassesDir() should be used instead. It seems like a small change which is easy to get fixed but I have no experience with building/publishing gradle plugins.
Please be warned (@lionel.faber) that if you upgrade Gradle the build(s) might fail.
