Java.lang.OutOfMemoryError: PermGen space error

I read all sorts of solutions for this. A link in the comments in

Working with java.lang.OutOfMemoryError: PermGen space error

- the best I've found so far. Pretty hard to follow though.

The fact is that I get this error by simply compiling the project with Maven.

As far as I know, there is still no application server. So what's going on?

So what can I do?

That's my fault:

Please check out this question: "java.lang.OutOfMemoryError: PermGen space" in the Maven assembly

(or)

Please view this link: http://vikashazrati.wordpress.com/2007/07/26/quicktip-how-to-increase-the-java-heap-memory-for-maven-2-on-linux/

If you get an OutOfMemory error when executing the mvn site, because of all the reports you generate, they simply increase the heap size for maven2. The way to do this is on Linux.

In your mvn.sh add this as the first line after copyright and other comments.

export MAVEN_OPTS = "- Xmx512m"

notice than Maven 2.0.6, some users have reported that double quotes give problems, so you can use

export MAVEN_OPTS = -Xmx512m
