Is it possible to launch a debugger such as jdb from Maven? I have a pom.xml file that compiles the project successfully. However, the program hangs somewhere and I would really like to launch jdb or an equivalent debugger to see what's happening.
I compile using mvn compile and launch using:
mvn exec:java -Dexec.mainClass="com.mycompany.app.App"
I was expecting something like:
mvn exec:jdb -Dexec.mainClass="com.mycompany.app.App"
to launch the debugger but, as usual, my expectations are incongruent with maven's philosophy.
Also, I couldn't find any documentation (on Maven's website or google) to describe how debugging works. I suspect that I have to use some plugin.
Just as Brian said, you can use remote debugging:
mvn exec:exec -Dexec.executable="java" -Dexec.args="-classpath %classpath -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044 com.mycompany.app.App"
Then in your eclipse, you can use remote debugging and attach the debugger to localhost:1044.
