Answer 1

The user2015131 suggestion inspired me to find my solution for this issue.

The problem

I explain my case, it may work for some people:

1. I installed Jenkins as a service a long time before on my slave machines.
2. I updated Java on the Jenkins' master computer.

So the Jenkins service's code stored on the slave is outdated.

The solution

Follow the next steps on every slave machine:

1. Update Java version.

   Be sure the Java version is the same or compatible with the one installed on the master computer.

2. Remove the old slave code. It's located inside the folder specified in the Remote Root Directory field under the node's configuration.

   I removed every jenkins-slave.* file, leaving only the jenkins_agent.pid file and the folders "remoting" and "workspace".

3. Go to the slave node interface on Jenkins from the web browser and click on the button.

   You will download a new JNLP file to install a new (updated) Jenkins service on the slave machine.

4. Run the downloaded file, go to menu and click on "Install as a service".

Hope it helps!
