How to fix java.lang.OutOfMemoryError: PermGen space error?

Question

Java

I'm trying to build the project, at a certain stage it displays:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile (default-compile) on project isup-impl: Compilation failure
[ERROR ] Failure executing javac, but could not parse the error:

[ERROR ] After correcting the problems, you can resume the build with the command
[ERROR] mvn -rf :isup-impl
As I understand it, the error is in the lack of PermGen space.
I set the parameters with the following command: export JVM_ARGS="-Xmx1024m -XX:MaxPermSize=256m"
MaxPermSize set both 512m and 1024m.
Maybe that's not the error? Or am I setting the parameters incorrectly?

In general, maven has its own environment variable - MAVEN_OPTS. Try to expose it. But in general, it is, to put it mildly, strange that when building a project, OOM PermGen comes out. What do you collect, if not a secret?
