My Jenkins instance was recently upgraded from 1.x to 2.48 behind a firewall with limited connectivity. While I recently got permissions configured to connect via a proxy to the Jenkins Update servers, I am unable to automatically install the JDK from Oracle.
So I manually uploaded the jdk-8u121-linux-x64.tar.gz to our Nexus server and configured the JDK auto installer to download from the Nexus URL.
When I run a job configured to use the new JDK + installer, I get the following error with no other apparent context as to why:
Installer "Extract *.zip/*.tar.gz" cannot be used to install "jdk1.8.0_121" on the node "jenkins-slave-01"
Any thoughts as to why this isn't working or what I should look at? I can't find anything in the logs.
Thanks!
