HI:

This plugin looks like do not support jar which build by java8.

I have a project, which dependency a jar compiled by java8.

When i build project with this plugin, it will show:

Configure project :app Jack is disabled, but one of the plugins you are using supports Java 8 language features. Jack is disabled, but one of the plugins you are using supports Java 8 language features. Dex: Error converting bytecode to dex: Cause: Dex cannot parse version 52 byte code. This is caused by library dependencies that have been compiled using Java 8 or above. If you are using the 'java' gradle plugin in a library submodule add targetCompatibility = '1.7' sourceCompatibility = '1.7' to that submodule's build.gradle file. UNEXPECTED TOP-LEVEL EXCEPTION:

Correct, this plugin has never supported running on libs. I recommend switching to the official tools if possible as it does.
