[netbeans] out of memory error, heap space

Have you tried to set ANT_OPTS enviroment variable? I have:

~$ echo $ANT_OPTS
-Xms2048M -Xmx2048M -Xss2M -XX:MaxPermSize=512M

But you can use smaller values if you don't build Scala from trunk (scaladoc 2
is *very* RAM hungry).

the thing is i'm on os x. there is a doc that says how to set SCALA_HOME for os x (http://wiki.netbeans.org/MacOSXEnvForApp), but that is system wide, and i would prefer not to set a system wide environment variable for JAVA_OPTS or ANT_OPTS ...

also....

since i couldn't further here, i reimported my stuff into eclipse. clean-compile is fine in just 35 seconds. so i'm sure there's something wrong with the compiler in the netbeans plug-in.... ?

The plugin uses bundled scala to run itself. For projects $SCALA_HOME and
$PATH are used.

ok, but how does it invoke scalac when i press the build button? it doesn't seem to execute $SCALA_HOME/bin/scalac, because if i add some test "echo"s in there, they don't show up....

so the question remains: how do i increase the build compiler's max heap memory?

thanks, -sciss-

NB uses ant script. Try to build a project from command line using project's
build.xml file.

I can not imagine it is impossible to set ANT_OPTS inside NB-starting script
only (not system-wide).

It invokes its own scalac and/or fsc.  These should be in your netbeans module directory.  On Linux with Netbeans 6.5 and the 2.7 module, it's ~/.netbeans/6.5/modules/scala, for example.

It isn't so fo NB 6.8 - it uses SCALA_HOME and PATH vars.

hmmm, running ant from the terminal gives the same error (despite ANT_OPT settings).

now running scalac directly from the terminal compiles all classes fine (with standard heap size!).... don't know what's going on there with netbeans build script, but i will just stick to this terminal compilation for the moment.

ciao, -sciss-

Do you have typo here only or in your scripts also? - I mean "OPT" where
"OPTS" must be used.

i used this

export ANT_OPTS="-Xmx1024m"

...

i have now set $ANT_OPTS globally (in ~/.MacOSX/environment.plot):

i still get the out-of-mem hangup:

i have at least my hope that a new netbeans plugin build will not exhibit this problem. i wasn't able to install the plug-in from sources. is there any chance getting a new binary?

i can compile from the shell but i need the step debugger ATM...

thanks a lot, -sciss-
