Some more information on this would definitely be helpful. I've mad mixed results with eclipse & gradle so far.
I have been able to debug java/groovy that's being called from gradle when running on anther system and using eclipse's remote java app debug config combined with the GRADLE_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5006"
Note that this needs to be set in the env, it's not picked up from ~/.gradle/gradle.properties as documented. Maybe I'm doing something wrong, but this is ignored: org.gradle.jvmargs="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5006"
I've had mixed results being able to stop on breakpoints when running as a remote java app. It's probably related to where eclipse is looking for src/class files and maybe I don't have that setup exactly right.
What I'd like to do is run gradle directly from eclipse directly and be able to hit breakpoints in my buildSrc/**/src/main/java classes.
I did the eclipse import gradle project for my project, and it recognizes it as a gradle project, but I don't see how to run/debug it from eclipse.
