问题
I'd like to use jdb with a gradle-built project.
The project's build instructions require running a ./gradlew run, which eventually launches a command like:
/abs/path/to/java -Dorg.gradle.appname=gradlew -classpath /abs/path/to/uaa/gradle/wrapper/gradle-wrapper.jar org.gradle.wrapper.GradleWrapperMain run
I replaced java with jdb,
jdb -Dorg.gradle.appname=gradlew -classpath /abs/path/to/uaa/gradle/wrapper/gradle-wrapper.jar org.gradle.wrapper.GradleWrapperMain run
then issue run, this runs the program correctly.
But when trying to set a breakpoint, I only see gradle-related wrapper classes and no classes defined by the project itself:
jdb$ classes
Press Ctrl-C to stop the container...

So I'm not able to set any useful breakpoints.
What is the best way to work around this, to be able to set a breakpoint in then class in which I'm interested (for example: org.cloudfoundry.identity.uaa.oauth.SomeClass.someMethod)?
I've tried
stop in org.cloudfoundry.identity.uaa.oauth.SomeClass.someMethod
stop in SomeClass.someMethod
and other combinations without luck
