export JAVA_HOME=`/usr/libexec/java_home` is exactly what you want to do.

In fact, all of the Apache projects (well, any project really) that hardcodes /System/Library/Frameworks/JavaVM.framework/Versions/... needs to use /usr/libexec/java_home if it exists. It's the only way you will know if Java is actually installed.

At some point in the future the symlinks in /System/Library/Frameworks/JavaVM.framework/Versions/ will be going away, which will even more severely break these projects if they want to load using an Oracle/OpenJDK JVM.

Thank you very much :) Do you, by any chance, know why one can't use double/straight quotation marks? – pasql Oct 18 '14 at 16:05
Will this be persistent between restarts? – IgorGanapolsky Apr 06 '16 at 13:13

Set JAVA_HOME to point to the .../Home directory, not the java binary. E.g.

export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Home

Why are you setting the environment variable in the first place? You shouldn't have to do this on OS X...

It is necessary, for example, when running ant build scripts. – IgorGanapolsky Apr 06 '16 at 13:14

In your .bashrc file, add below lines:

export JAVA_HOME=/usr
export PATH=$PATH:$JAVA_HOME

This worked for me.

Add the following line to ~/.mavenrc file

export JAVA_HOME=$(/usr/libexec/java_home)

Reference: Maven ignoring JAVA_HOME on OSX?

Some times changing Java_HOME does not help, because in apache ant script the java_home is hardcoded. If when you change the JAVA_HOME still failed to run ant, you can try to change the default hardcode to your JAVA_HOME in ant script, like:

    $ vi /Users/apache-ant-1.8.3/bin/ant 
    #ant from line 83 to 93
    case "`uname`" in
      CYGWIN*) cygwin=true ;;
      Darwin*) darwin=true
               if [ -z "$JAVA_HOME" ] ; then
 #delete JAVA_HOME=XXXXX(default line) , and give JAVA_HOME ur java home url       




JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home
                           fi
                           ;;
                  MINGW*) mingw=true ;;
                esac

This can also happen because of the misconfigured jenv, in case it is installed.

In the ~/.bash_profile, there should be these 3 lines:

export PATH="$HOME/.jenv/bin:$PATH"
eval "$(jenv init -)"
eval "$(jenv enable-plugin export)"

Then reload it by: source ~/.bash_profile
