Thanks Mark.
You are right that geronimo doesn't reset MAVEN_OPTS. The root cause is that I have %HOME%\mavenrc_pre.bat on my machine, which reset MAVEN_OPTS.

han, it's not reset in the build.

However, a few tasks are forked by maven, so they do not inherit your environment settings.

For those cases you might try to export MAVEN_OPTS=...

Thanks Rex. But the same error occur.
Upgrading -Xmx and -XX:MaxPermSize may solve the out of memory problem, but the point is the environment variable MAVEN_OPTS got changed (from "-Xmx1024m -XX:MaxPermSize=256m" to "-Xmx512m") during geronimo build, and my setting doesn't take effect to solve the out of memory.

Is MAVEN_OPTS reset somewhere when building geronimo?

same here, upgrading to PermGenSpace of 512m did help.

But currently the build still fails while building the tomcat7 integration:

try another OPTs?..

JAVA_OPTS     -Xms256m -Xmx1024m -XX:MaxPermSize=256m

I'm trying to build geronimo server trunk with sun jdk 1.6.0_20 on my winXP. I have this environment variable set.
         MAVEN_OPTS = -Xmx1024m -XX:MaxPermSize=256m
Before issue the build command, I echo this variable in command prompt window, and I can see the value is exactly what I have set (-Xmx1024m -XX:MaxPermSize=256m).

Then I issue the build command (i.e., mvn clean install) in the root dir of trunk, the build gets failed in serveral minutes with error msg indicates out of memory.

[INFO] Compilation failure
Failure executing javac, but could not parse the error:

The system is out of resources.
Consult the following stack trace for details.
 at java.util.ArrayList.newElementArray(Unknown Source)
 at java.util.ArrayList.growAtEnd(Unknown Source)

 at java.util.ArrayList.add(Unknown Source)
When I echo the environment variable again, but its value changes to "-Xmx512m".
Does somebody know what happened to MAVEN_OPTS? Why its value changes after build command?
