[classlib]InvocationTargetException

I am trying to build the class library following the steps described
at http://harmony.apache.org/quickhelp_contributors.html

My OS is Ubuntu Feisty

>From [Harmony]/trunk/working_classlib/
Ant fails with
[...]/build.xml : 113[..]
[..]/make/build-java.xml:130 : java.lang.reflect.InvocationTargetException


Any idea where I may have missed something ?

Thanks for your help.

That was exactly a heap size issue.

Actually that was explained in a note I had missed :
" If you do choose to build from the federated build root, you may
need to increase the Java heap available to Ant. We suggest setting
the "ANT_OPTS" environment variable as ANT_OPTS='-Xms256m -Xmx512m' in
the manner appropriate for your operating system.
Populating the VM and ClassLibrary Source Trees "

Thanks for your help

I get this error unless I set ANT_OPTS="-Xms256m -Xmx512m". The default 
heap size is just not enough to compile whole classlib, so I get 
OutOfMemoryError that causes InvocationTargetException.

Looks like you are missing a java compiler?  Make sure you have a jdk 
installed.  (apt-cache search jdk might help.)
