java_home没有定义_“错误：JAVA_HOME没有正确定义.”在构建Jikes rvm

当我在Ubuntu上构建Jikes RVM时,我收到了这个错误.任何的想法？

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 "'

Error: JAVA_HOME is not defined correctly.

环境变量：

路径

/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

我检查了JAVA_HOME / bin目录下的java,它可以工作.

无论我如何改变环境变量,错误一直在抱怨

“We cannot execute /opt/jdk1.6.0/bin/java”.

似乎我没有修改正确的“位置”.
