maven-exec-plugin and VM args
Hey all,
Seeing some odd behaviour with maven-exec-plugin and JVM arguments that
seem to be eluding me. I have the following config:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.2.1</version>
<configuration>
<executable>java</executable>
<classpathScope>test</classpathScope>
<longClasspath>true</longClasspath>
<arguments>
<argument>-Dcom.sun.management.jmxremote -Djava.awt.headless=true -Xmx1024m
-XX:MaxPermSize=256m
-XX:+HeapDumpOnOutOfMemoryError
</argument>
<argument>-Xdebug
-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005
</argument>
........
</configuration>
<executions>
<execution>
<id>integration-tests</id>
<phase>test</phase>
<goals>
<goal>exec</goal>
</goals>
</execution>
</executions>
and yet when I run the plugin, I see all the arguments being passed to
the command line of the process, but the process never seems to setup
the debug options, or suspend the server till I connect, or update the
permgen.
Looking at the output of ps on my Mac everything looks like it should be
ok.... am I missing something blindingly obvious?
Cheers
Mark

Anders,
Mmm that sounds plausible altho so far I don't seem to see any
difference in behaviour, my "ps aux" output shows
amrk 6040 0.0 5.7 4054184 478464 s000 S+ 10:53am 3:57.72 /usr/bin/java

-XX:MaxPermSize=256m -XX:+HeapDumpOnOutOfMemoryError -Xdebug
-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005

/var/folders/vx/7v3qnlc53lgbm19_nn0g59_r0000gn/T/maven-exec36536174902264218.jar
which all looks like it should be starting a debug session and
suspending. hrm.

I think I ran into something similar the other day. You need to put each of
the arguments in a separate argument element.
<argument>-Dcom.sun.management.jmxremote</argument>
<argument>-Djava.awt.headless=true</argument>
<argument>-Xmx1024m</argument>
etc.
/Anders
