Maven does not find JAVA_HOME in Fish shell
After reinstalling java from brew cask, it could happen that Maven does not find anymore the JAVA_HOME. The error looks like this:
$ mvn clean install
The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
NB: JAVA_HOME should point to a JDK not a JR
In Fish shell, on Mac OS X, the solution is to set the variable in universal mode:
$ set -U JAVA_HOME (/usr/libexec/java_home)
