java.lang.OutOfMemoryError: PermGen space error
I've read all kind of solutions for this. A link in a comment in
Dealing with “java.lang.OutOfMemoryError: PermGen space” error
is the best I've found so far. Pretty complicated to follow though.
The point is, I get this error just compiling a project with Maven.
To my knowledge there is no aplication server so far. SO what's going on?
And what can I do?
This is my error:

Exception in thread "main" java.lang.OutOfMemoryError: PermGen space
Answer
Please see this question: "java.lang.OutOfMemoryError: PermGen space" in Maven build
(or)
Please see 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 error OutOfMemory error while doing mvn site, because of all the reports that you are generating, just increase the heap size for maven2. The way to do that on linux.
In your mvn.sh add this as the first line after the copyright and other comments.
export MAVEN_OPTS=”-Xmx512m”
note than Maven 2.0.6 onwards some users have reported that the double quotes give problems, hence you might want to use
export MAVEN_OPTS=-Xmx512m
