JAVA_HOME not found as Sudo

Question

I have a bash script on a Linux box that runs a Jar file. When logged in as a regular user I don\'t have permission to run the script, but it prints the following log:

Answer 1

"sudo -E " didn't solve the problem when JAVA_HOME was not exported. And when it was exported, "sudo " without -E works the same.

So you can add export JAVA_HOME=.../jdk<version> in your .bash_profile and .bashrc file.

In case you wondered what's the difference of .bash_profile and .bashrc, .bash_profile is executed upon login (e.g., show some diagnostic/welcome information). .bash_rc is executed when you open a new terminal (e.g., shift-ctrl-T).

In order to run some commands for both cases, you can put it in .bashrc file, and let .bash_profile source .bashrc:

if [ -f ~/.bashrc ]; then
   source ~/.bashrc
fi

Answer 2

By default, sudo will cleanup the environment of the spawned commands. Pass -E to keep it:

sudo -E env

Compare to:

sudo env

Answer 3

You could always just pass it to java explicitly like this:

sudo java -Djava.home=$JAVA_HOME Test
