"Error: JAVA_HOME is not defined correctly." in building Jikes rvm

When I built the Jikes RVM on Unbuntu, I got this error. Any idea?


bin/buildit localhost production
---> Config: production
/bin/bash --login -c '/bin/bash --login -c " cd /home/jack/Programs/jikesrvm-3.1.2 && export JAVA_HOME=/opt/jdk1.6.0 && ant very-clean -Dhost.name=ia32-linux && ant check-components-properties -Dhost.name=ia32-linux -Dtarget.name=ia32-linux -Dcomponents.cache.dir=/home/jack/.buildit_components_cache && ant -Dtarget.name=ia32-linux -Dconfig.name=production -Dhg.revision= -Dhost.name=ia32-linux -Dcomponents.cache.dir=/home/jack/.buildit_components_cache "'

OS:

Linux ubuntu 2.6.32-24-generic #39-Ubuntu SMP Wed Jul 28 06:07:29 UTC 2010 i686 GNU/Linux


Environmental Variables:
PATH

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/lib/jvm/java-6-sun-1.6.0.22/bin


JAVA_HOME

/usr/lib/jvm/java-6-sun-1.6.0.22


I checked the
java
in the
JAVA_HOME/bin
directory, it works.
No matter how I change the environmental variables, the error kept complaining "We cannot execute /opt/jdk1.6.0/bin/java". It seems that I didn't modify the right "position".

Any clue?

Thanks!

Answer

run this command:

find . -exec grep "jdk1.6.0" {} \;

To find out which file is setting JAVA_HOME to that path.
