Setting the JAVA_HOME and PATH on MacOS

Question

I want to execute build.xml file using ant. But I am having trouble with recognizing the path for ant and Java. I tried changing the location to the correct location in bashrc as well as tried changing it for current command window using following commands:

export path=/usr/local/apache-ant/bin:"$PATH"
echo 'export path=/usr/local/apache-ant/bin:"$PATH"' >> ~/.profile

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/bin:"$PATH"

similarly echo to profile for JAVA_HOME But when I check the paths for these they are not changed. Am I missing something?

echo $path
/usr/local/apache-ant/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin


echo $JAVA_HOME
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

Thanks for your help

Answer 1

It's PATH not path, and your JAVA_HOME is not under "Internet Plug-Ins" - try a find / -name "javac". Also, are you sure that you've installed Java? Finally, after you have set your JAVA_HOME correctly do a

export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home"
export ANT_HOME="/usr/local/apache-ant"
export PATH="$PATH:$JAVA_HOME/bin:$ANT_HOME/bin"

Check that it works correctly with:

java -version
ant -version

Then add the export lines to ~/.bash_profile or /etc/profile.
