----------------------------

> [dev list mailing reference: Debugging maven with breakpoints feed-back:
> --jdwp + docs]
> Problem:
> Currently its hard to enable remote debugging for a remote debugger of your
> IDE.
> Basically you need to set MAVEN_OPTS something like:
> export MAVEN_OPTS="-Xdebug -Xnoagent -Djava.compiler=NONE
> -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000"
> mvn ...
> and unset it again.
> Solution:
> 1) Make it easier, choices:
> A) Provide a command line option to do this (--debug is already taken for
> debug logging), choices:
> a) mvn --jdpa
> b) mvn --jdwp
> B) Provide a different script: mvnDebug
> to avoid parsing command line arguments in bat and shell
> C) Find a generic way to give options on the command, like -mx etc to the
> java process, possibly by namespacing them?
> 2) Document it in mvn --help
> 3) Document it on
> http://maven.apache.org/guides/development/guide-m2-development.html
> like so (APT):
> Debugging with breakpoints
> You can attach a remote debugger of your IDE to the maven process.
> This will allow you to set breakpoints (line, exception, ...).
> Start maven in debugger mode on port 8000:
> +--
> mvn ??? install
> +--
> If you want to change any of the debugger settings,
> use MAVEN_OPTS instead.
> Then connect to the correct port with a remote debugger in your IDE.
