Jenkins Troubleshooting Tips Related to Path Errors

Agent paths for a user are derived seperately from the linux user path

So being ssh’d into a machine and running echo $PATH is not the true output

Instead, run the following from the node side script console in the Jenkins web gui

println System.getenv("PATH")

These variables are cached, to get to reload you may have to disconnect the node and relaunch it

Update java version

sudo update-alternatives --config java

The above will set the java variables accordingly
