Jenkins - Executing a script before any build job built

Question

I'd like to execute a script before I execute any project/build on a Jenkins server. I've checked out the BuildWrapper script and a couple of others.

These all seem to be based on a specific job, but I'd like to get this sorted to work across any job/build on this server.

Answer 1

You could add an upstream job that all jobs depends on.

Specifically, In the buildsteps of your job, you can choose "Trigger/Call builds on other projects", add ParentJob and select "Block until the triggered projects finish their builds" before invoking the buildsteps of your job.
