OutOfMemory exception when using Maven in ant

Hi there,

 

I am trying to incorporate Maven dependency management into my ant build as follows:

 

        <artifact:dependencies pathId="my.dependencies.class.path">

            <dependency groupId="org.lib"

                        artifactId="libtools"

                        version="1.1.1"/>

            <dependency groupId=" org.lib "

                        artifactId="otherlib"

                        version="1.1.1"/>

            <remoteRepository refid="archiva.repository"/>

        </artifact:dependencies>

 

When I do a clean build, i.e. 'ant clean my-target', I get the following exception:

java.lang.OutOfMemoryError: PermGen space

 

Can someone help explain what is going on here and how I might mitigate this problem?  Once I have this working for the first classpath, I plan to change all my classpaths to use the repository, but this looks like a bit of a show-stopper.

 

Thanks in advance,

Ron

This looks like an ant problem.
You could try to increase the memory defaults in your Java VM.
Make them really big and then pare them down if you feel the need to be 
precise (No value in that technically).

This is a Java problem rather than a Maven or Ant one.
It has to do with not enough memory to load all the classes into the
PermGen space.
You can read up about PermGen space to get more of an idea as well
* http://www.oracle.com/technetwork/java/javase/memleaks-137499.html#gbyuu
* http://java.dzone.com/articles/busting-permgen-myths

See http://stackoverflow.com/questions/88235/dealing-with-java-lang-outofmemoryerror-permgen-space-error
for some solutions.

It talks about Tomcat, but the problem occurs in command line Java.
As a workaround use (or large values than 128M if needed)
    -XX:MaxPermSize=128M

Also look at similar XX options at
