As already written by Mark, you should NOT install things into /etc. It's 
neither meant for storing binaries (this is Linux, not HPUX), nor is it on the 
PATH, thus it cannot be found. If you install it from distribution packages, it 
will be installed into the correct location, where it can then be found when 
you launch the agent.

Otherwise, provide the full path to it in the agent configuration.

HTH...

Re: Jenkins not able to launch the slave due to unrecognizable JAVA_HOME

2024-04-18 Thread Ivan Fernandez Calvo 
[SSH] The remote user's environment is: Checking Java version in the PATH 
Java is not in the PATH nor configured with the javaPath setting,

What happens if you enter by SSH in the agent with the same user you use to 
connect the Jenkins controller and execute java?

>ssh my-jenkins-user@my-ssh-agent
>java

I will guess

>command not found
