Maven: OutofMemoryError followed by Could not create the Java virtual machine
java, maven, maven-2, out-of-memory
Solution
you can try to set the initial heap size and initial permgen size relatively small, but set the proper max heap and pergent via -Xms128m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=256m
Also don't set permgen to 512 - it's too much for typical scenarious.
Also you may want to use fork option with maven and start plugin execution in different JVMs at all.
For example
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.5.1</version>
<configuration>
<fork>true</fork>
</configuration>
</plugin>
Also, while allocating memory also make sure that you have that much free memory available.
Problem
I am trying to use maven for my project work but i am stuck with memory related issues. When i run the maven i get the heap space error which i fixed using the following line ``` set MAVEN_OPTS="-Xmx1586m" ``` after this when i run the maven again, i don't get the heap space error but rather i get the PermGen space error. For solving that i used the following syntax ``` set MAVEN_OPTS="-Xmx1586m -XX:MaxPermSize=512m" ``` but once i start using the MaxPermSize option i get the following error Invalid maximum heap size: -Xmx1586m -XX:MaxPermSize=512m Could not create the Java virtual machine. I have tried setting different value combination for Xmx and MaxPermSize to bring the size in control but all are invalid. I get this error only when i put MaxPermSize option in the MAVEN_OPTS. Once i remove that option i don't get the error mentioned above but i do get the PermGen error. Any suggestions what I am doing wrong?
