Program type already present: org.intellij.lang.annotations.JdkConstants$PatternFlags

[d4rken]

Upgrading Timber from 4.7.0 to 4.7.1 in a library of mine, causes another app using that library to fail building with this error.

AGPBI: {"kind":"error","text":"Program type already present: org.intellij.lang.annotations.JdkConstants$PatternFlags","sources":[{}],"tool":"D8"}

This can be fixed by including in my build.gradle

configurations {
    cleanedAnnotations
    compile.exclude group: 'org.jetbrains' , module:'annotations'
}

Might be related to #327

I'm seeing this error after switching on R8 using android.enableR8=true in Android Studio 3.3.1. Works fine with R8 disabled (but proguard enabled). Timber version is 4.7.1.

Still seeing this, I'm still using the posted workaround. I'm not using enableR8
