How do I increase memory given to maven-glassfish-plugin?

I'm using the Maven plugin for embedded Glassfi开发者_Python百科sh - here's my plugin declaration:

<plugin>
  <artifactId>maven-glassfish-plugin</artifactId>
  <packaging>maven-plugin</packaging>
  <version>1.0-alpha-4</version>
  <configuration>
    <httpPort>8080</httpPort>
  </configuration>
</plugin>

After several clicks through my data-intensive web app, I run out of PermGen space.

java.lang.OutOfMemoryError: PermGen space

I've already configured MAVEN_OPTS to use more memory:

set MAVEN_OPTS=-Xmx1024m

But it looks like the Java process spawned by mvn glassfish:run is only getting about half a gigabyte of memory before it seizes up.

Does the Glassfish plugin have any configuration settings for upping its memory?

Thanks!

Just to clarify. The permanent generation space contains loaded class objects and interned strings. It is allocated outside of the Java heap as illustrated below:

On recent Sun VMs, the default maximum size is 64m (i.e. -XX:MaxPermSize=64m) and is adequate for most applications (the problem is very likely related to frequent undeploy/redeploy here though). I would anyway try with -XX:MaxPermSize=128m or -XX:MaxPermSize=256m, 1024m seems really oversized!

After further consultation with some colleagues, it seems I was increasing the wrong memory value in Maven.

To increase PermGen space, I added this to my MAVEN_OPTS:

set MAVEN_OPTS=-Xmx1024m -XX:MaxPermSize=1024m
