Since I wind up testing things on multiple JDKs frequently, I thought I'd share a handy tool for quickly swapping both JAVA_HOME, and its values from $PATH:
http://timboudreau.com/files/fixpath You just set up shell aliases source the output of it. Usage: 0. Have nodejs on your path (depending on your Linux distro, you may need to change the shebang at the top to reference "nodejs" instead of "node" - Debian based distros use "nodejs") 1. Copy this script to some place like ~/bin/fixpath (you'll use that in the shell aliases0 2. Set up some environment variables for different JDKs in your .bashrc: export JDK_7=/opt/jdk7 export JDK_8=/opt/jdk8 export JDK_9=/opt/oracle-jdk-bin-9.0.4 export JDK_10=/opt/jdk10 export JDK_14=/opt/jdk14 3. Set up some aliases in your .bashrc too: # Fast switch java versions for the current shell alias jdk7='. <(~/bin/fixpath JDK_*/bin JDK_7/bin JAVA_HOME)' alias jdk8='. <(~/bin/fixpath JDK_*/bin JDK_8/bin JAVA_HOME)' alias jdk9='. <(~/bin/fixpath JDK_*/bin JDK_9/bin JAVA_HOME)' alias jdk14='. <(~/bin/fixpath JDK_*/bin JDK_14/bin JAVA_HOME)' alias jdkGraal='. <(~/bin/fixpath JDK_*/bin JDK_GRAAL/bin JAVA_HOME)' 4. Open a new shell, or `. ~/.bashrc` and you're good to go. Just run the command jdk14 and you're using JDK 14, etc. Thought I'd share, Tim -- http://timboudreau.com
