"Invalid Maximum heap Size" when running Maven

Run MVN package, error:

Invalid maximum heap size: -Xmx512m.Error: Could not create the Java Virtual Machine.Error: A fatal exception has occurred. Program will exit.

Workaround One:

Alter Jvm.config in. MVN directory (it was in Controller directory). Study mvn.sh that comes with Maven. You'll see maven_opts setting in the script. Try out java-version before altering. Eg: java-xmx512m-version Now what know how to go about and make the changes.

Workaround Two:

You can try to set the initial heap size and initial permgen size relatively small, but set the proper Max Heap and Pergen T via-xms128m-xmx1024m-xx:permsize=128m-xx:maxpermsize=256m

Also don ' t set PermGen to 512-it's too much for typical scenarious.

Also 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 and that's the much free memory available.
