Jenkins Groovy Postbuild uses a static file instead of a script

Is it possible to load an external groovy script into the post w build groovy plugin instead of pasting the contents of the script into each job? We have about 200 tasks, so updating them is rather laborious. I know that I could write a script to directly update the configuration files (as in this post: Add Jenkins groovy Postbuild step for all jobs ), but these jobs work 24x7, so finding a window when I can restart Jenkins or reload the configuration is problematic .

Thank!

I ran into the same problem and tried using the @Blaskovicz approach. Unfortunately, this did not work for me, but I found the updated code here (Zach Auclair)

Publication here with minor changes:

task after creation

//imports
import hudson.model.*
import groovy.lang.GroovyClassLoader;
import groovy.lang.GroovyObject;
import java.io.File;

// define git file
def postBuildFile = manager.build.getEnvVars()["WORKSPACE"] + "/Jenkins/SimpleTaskPostBuildReporter.GROOVY"
def file = new File(postBuildFile)
// load custom class from file
Class groovy = this.class.classLoader.parseClass(file);
// create custom object
GroovyObject groovyObj = (GroovyObject) groovy.newInstance(manager);
// do report
groovyObj.report();

postbuild class file in git repo (SimpleTaskPostBuildReporter.GROOVY)

class SimpleTaskPostBuildReporter {
  def manager

  public SimpleTaskPostBuildReporter(Object manager){
    if(manager == null) {
      throw new RuntimeException("Manager object can't be null")
    }
    this.manager = manager
  }

  public def report() {
    // do work with manager object
  }
}
