Thanks in advance
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.
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...
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
