Maven "Exception in thread "http-bio-8080-exec-32" java.lang.OutOfMemoryError: PermGen space"
java, maven, netbeans, permgen
Solution
You should add this line:
export MAVEN_OPTS="-Xmx512M -XX:MaxPermSize=512M"
Note that some users have reported that the double quotes give problems, hence you might want to use:
export MAVEN_OPTS=-Xmx512M -XX:MaxPermSize=512M
EDIT:
Since you are using Tomcat, use this:
- Open up tomcat/bin/catalina.sh
- add this line to the JAVA_OPTS="-Djava.awt.headless=true -Dfile.encoding=UTF-8 -server -Xms512m -Xmx1024m -XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=256m -XX:MaxPermSize=256m -XX:+DisableExplicitGC"
- Save and exit , restart Tomcat

Problem
I made a project in NetBeans under Ubuntu 11.10 with Struts2 + Spring and Hibernate frameworks. The first run is ok, but when I run it for the second or third time I keep getting this exception. Without Maven all goes well. I installed maven with `apt-get install`, and yes I added this line `export MAVEN_OPTS=-Xmx512m` in `usr/bin/mvn`, but without luck. How to get a better performance from it?
