Test runs fine in Eclpse with 256m, breaks with Maven
Good morning Mavens!
Running a unittest configured with Xmx256M in Eclipse runs fine.
Running the same test with Maven on the prompt with set MAVEN_OPTS="-Xmx1024m" results in a Caused by: java.lang.OutOfMemoryError: Java heap space
What could be the reason that running the test on the prompt results in a Java Heap Space problem (while in Eclipse it runs fine)?
My configuration is Maven 3.0.3, Java jdk1.6.0_16.
Thanks for commenting,
Erik

And the reason it might run fine in Eclipse is because you might have
put -Xmx in your Eclipse JRE default JVM arguments (in Preferences). In
any case, the JVM is invoked with a different classpath by Eclipse.

MAVEN_OPTS only affects Maven itself, not the new JVM instance it starts
(by default) to run unit tests for each module. For a full-featured
example of how to increase the heap of the JVM used for tests (a new one
is created for each module), see the maven-surefire-plugin settings in
the GeoTools root pom:
http://svn.osgeo.org/geotools/trunk/pom.xml
In a nutshell, you need to set your -Xmx option in
plugins/plugin/configuration/argLine in your pom.
Kind regards,
Ben.

How are you executing in Eclipse?
How are you executing from CLI?
