Apply retrolambda to custom JavaCompile tasks about gradle-retrolambda HOT 4 CLOSED

The major problem you'll run into is you need certain java 8 classes on the classpath for retrolambda to work. Have you considered using https://github.com/xvik/gradle-animalsniffer-plugin?

from gradle-retrolambda.

It's not well documented but to you can create a retrolamda task. Check out the source for the java plugin https://github.com/evant/gradle-retrolambda/blob/master/gradle-retrolambda/src/main/groovy/me/tatarka/RetrolambdaPluginJava.groovy

from gradle-retrolambda.

Thanks for your quick answer. Right now I wonder if I can even achieve what I want to achieve using Retrolambda: Writing Java 8 source code and linking that code against an android.jar of the corresponding Android API level. For this it seems to the required that retrolambda compiles the Java 8 source to Java 7 class files with simultaneously using the android.jar as boot classpath. But Retrolambda is only able to desugar Java 8 class files to Java 7 class files. Correct?

AnimalSniffer perfectly solves my use case, Thank you very much for pointing this out.
