New Relic Android agent error with gradle

Question

I have a project that uses the gradle build system and I'm willing to add New Relic monitoring to it.

The project (including New Relic) is working fine on Linux (Fedora 20), but won't build on my Mac development system, and gives out an error stating Agent JAR loaded but agent failed to initialize.

Here is the full log of the error:

Dev-1:test 0x4d$ ./gradlew clean
> Configuring > 1/2 projects > :appobjc[4437]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.7.0_55.jdk/Contents/Home/bin/java and /Library/Java/JavaVirtualMachines/jdk1.7.0_55.jdk/Contents/Home/jre/lib/libinstrument.dylib. One of the two will be used. Which one is undefined.

I have also tested with a freshly generated, bare-bones project, but it fails with the exact same error.

I use the JDK 1.7u55 version, if that matters.

Thanks

Unfortunately u55 introduced a change that breaks the New Relic agent. For now, if possible, use an older version of Java to work around this issue while building. This shouldn't affect the resulting APK. New Relic is aware of this issue and is working to fix it as fast as possible.
