Hi
I just copied mvn.bat to mvnd.bat (d = debug), added
set MAVEN_OPTS=... line and that's all.
You can do the same in maven-core sources.

I've thought about this in the past, but have always opted to go for
setting MAVEN_OPTS (which I have in a separate little script).
I'd be fine with adding this argument, but parsing the command line
arguments (especially in the .bat file) can be a bit of a pain.
Would someone like to put it in JIRA?

Geoffrey,
I like it! I prefer more --jdpa rather than --jpwd (Think about geronimo
or tomcat)
What do others think?

2006/2/22, Geoffrey De Smet <[EMAIL PROTECTED]>:
I just used my first debug breakpoint in maven 2 to fix the
jasperreports plugin:
export MAVEN_OPTS="-Xdebug -Xnoagent -Djava.compiler=NONE
-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000"
mvn <phase-on-my-project>
Still, this is a bit unhandy and it took me quite a while to find out.
So here's my 2 cents feed-back:
1) Some sort of mvn --jdwp (mvn --debug is already taken for debug
logging).
If it's already there, please document in "mvn --help".
2) Document how to do this with a short APT, for example in
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 --jdwp
+--
If you want to change any of the debugger settings,
use MAVEN_OPTS instead.
Then connect to it with a remote debugger in your IDE.
