如何在ubuntu中设置环境变量ANT_OPTS？

Question

在Ubuntu 10.0.4中设置liferay环境时,我在.bashrc文件中设置了这样的环境变量

PATH=/usr/bin/java/jdk1.7.0_51/bin:$PATH
export PATH

JAVA_HOME=/usr/bin/java/jdk1.7.0_51
export JAVA_HOME

PATH=/usr/bin/ant/bin:$PATH
export PATH

ANT_HOME=/usr/bin/ant

export ANT_HOME

ANT_OPTS="-Xmx1024m -XX:MaxPermSize=256m"

export ANT_OPTS

set path=$path $ANT_HOME/bin

我在我的终端中测试了这样的环境变量:

sudheer@VY-B3:~$ echo $PATH
/usr/bin/ant/bin:/usr/bin/java/jdk1.7.0_51/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
sudheer@VY-B3:~$ echo $JAVA_HOME
/usr/bin/java/jdk1.7.0_51
sudheer@VY-B3:~$ echo $ANT_HOME
/usr/bin/ant
sudheer@VY-B3:~$ echo $ANT_OPTS
-Xmx1024m -XX:MaxPermSize=256m

在为liferay运行build-themes时遇到以下错误:

Buildfile: /home/sudheer/Desktop/Life-ray/Liferay_workspace/portal/portal-web/build.xml

BUILD FAILED
/home/sudheer/Desktop/Life-ray/Liferay_workspace/portal/portal-web/build.xml:4: The following error occurred while executing this line:
/home/sudheer/Desktop/Life-ray/Liferay_workspace/portal/build-common-web.xml:4: The following error occurred while executing this line:
/home/sudheer/Desktop/Life-ray/Liferay_workspace/portal/build-common.xml:393: .

Please set the environment variable ANT_OPTS to the recommended value of
"-Xmx1024m -XX:MaxPermSize=512m".

最后我设置了这样的环境变量：

# Java environment variables

JAVA_HOME=/opt/java/jdk1.7.0_51
export JAVA_HOME

PATH=$JAVA_HOME/bin:$PATH
export PATH


ANT_HOME=/opt/apache-ant-1.7.1
export ANT_HOME

PATH=$ANT_HOME/bin:$PATH 
export PATH 

ANT_OPTS="-Xmx1024m -XX:MaxPermSize=512m"
export ANT_OPTS

在.bashrc文件中，我已经在终端中打开了eclipse..现在它工作正常..
