I have not been able to upgrade past Groovy 1.5.8, due to massive memory
issues. I've identified the exact scenario that cause problems, but I
don't know if it is a bug, or what the solution is.
The <groovy> task can be used as long as the taskdef is done once, or
the taskdef uses loaderref when done in a loop. But, if the loop calls
a sub project, (eg antcall) the loaderref attribute does not help.
The <scriptdef language="groovy"> task seems to have the exact same
behavior as the <groovy> task.
The <script language="groovy"> task cannot be used in a loop, since
there is no way to separate the script execution from the groovy
task/script definition.
Any help would be greatly appreciated.
Thanks, Mike
PS - Attached is the script I used for diagnosing this. It uses
AntContrib to loop. It can run as follows:
ant -f GroovyMem.xml -Diterations=100 -D3rdparty_libdir=
\3rdPartyJars\lib
