MOE 1.3.4 moeMainProGuard task fails in Android Studio

So I think I see the problem for this one but I don’t think it’s something fixable on my side of things. I just build my app that was building fine with MOE 1.3.3 but the moeMainProGuard task fails with the following error:

ProGuard, version 5.2.1 The same input jar [/Users/myname/.moe/moe-sdk-1.3.4/tools/java8support.jar] is specified twice.
at proguard.ConfigurationChecker.checkConflicts(
at proguard.ConfigurationChecker.check(
at proguard.ProGuard.execute(
at proguard.ProGuard.main(

Looking in reveals that there is both an -injars and -libraryjars entry for this jar. Specifically I have

-injars /Users/myname/.moe/moe-sdk-1.3.4/tools/java8support.jar(!**.framework/**,!**.bundle/**)


-libraryjars /Users/myname/.moe/moe-sdk-1.3.4/tools/java8support.jar

When I downgrade to MOE 1.3.3 there’s only a -libraryjars entry for it and the app works fine. So whatever generates the base file seems to be what’s causing it. Is there any way for me to fix this or just wait for a patch? Any way to cancel the entry out using the proguard.append.cfg file?


I just pushed a hotfix for this as moe-gradle 1.3.5.

Only the Gradle plugin is updated, you can force it using ./gradlew --refresh-dependencies
