Maven throws the Exception or the IDE? In any case, have you tried increasing
the heap for the JVM?

and.

I run on MAc. I have eclipse.ini in the folder where eclipse.app is launched.

It contains

-XX:MaxPermSize=512m

-Xms512m

-Xmx4096m

I see OOM error on, when i right click the pom file => Run As => Maven Build.

I do not specify any VM arguments in JRE tab.

Regards,

Deepak

Why not? Try it :-)

Maven is launching its own JVM, so the Eclipse settings aren't propagated to
this new instance.

[Deepak Jain]

Oh, i tried these. I still see the exception.

[Deepak Jain]

I do i give memory to maven JVM ?

When i right click => Run as => Maven Build => JRE Tab => VM Arguments ?

Do i give more memory here ?

Yes, I'd try that.

[Deepak Jain]

Same error.

Tried setting memory at three levels

1) Eclipse.ini

2) JRE Tab of Maven Run

3) scala-maven-plugin

Nothing seems to be working

Hmm... are you maybe forking a vm in your build? Does the build work when you
run it outside of Eclipse?

[Som Snytt]

That's a Scala 2.10 stacktrace.

I recall a bug in that "supplementErrorMessage", or revealed there, but I don't have time to research ATM.
