Ant script gets killed but not with -verbose

I am running an ant script using ant -f build.xml. This script is supposed to compile my project and generate a jar file but some seconds after ant starts to generate the jar file, the project gets killed and all I see is the message "Killed" in the console.

If I run the s开发者_运维百科ame command but with the "-verbose" option, the build finishes successfully.

Any ideas?

Thanks.

Update: This is the ant output i get:

Buildfile: build.xml

compile:

jar:
  [jar] Building jar: /var/lib/hudson/jobs/asproj/workspace/build/asproj.jar
Killed

This is the dmesg output I get after the process is killed:

Out of memory: kill process 16398 (bash) score 13929 or a child
Killed process 1499 (java)

So it's probably memory related, but it's not the ant jvm.. it has something to do with the bash process.

You can try increasing JVM size using ANT_OPTS -

set ANT_OPTS=-Xms500m

This sets JVM size to 500 MB.
