Jenkins: change the build history from different job - jenkins

Question

I have two jenkins jobs:
build the project
deploy it
Both are working well and I can trigger the deploy job from the project build job.
Steps:
Build with parameters in the application's job >> check deploy on dev >> build
Add a yellow star badge to the build history in the application job - with groovy post-build action (code below)
Trigger the deploy job as post-build action
Question
After the deploy job was finished and failed change the build history of the application job (yellow star >> eg red one) - from the deploy job. How can I do that?
if ("true".equals(manager.build.buildVariables.get('DEPLOY_ON_DEV'))) {
manager.addBadge("star-gold.gif", "SNAPSHOT deployed on DEV")
}

This took me a while to develop but now it works like a charm in Post-build Actions → Add post-build action → Groovy Postbuild → Groovy script:
import hudson.model.Build
import hudson.model.Cause
import hudson.model.Project
import jenkins.model.Jenkins
import org.jvnet.hudson.plugins.groovypostbuild.GroovyPostbuildAction
def log = manager.listener.logger
log.println(' ----------------')
log.println(' Groovy Postbuild')
// decorate this build
manager.addShortText('SNAPSHOT deployed on DEV', 'black', 'gold', '1px', 'black')
manager.addInfoBadge('SNAPSHOT deployed on DEV')
manager.addBadge('star-gold.png', 'SNAPSHOT deployed on DEV')
// decorate upstream builds
Jenkins jenkins = Jenkins.getInstance()
List<Project> projects = jenkins.getAllItems(Project.class)
log.println(" This build: '${manager.build}' --> " + manager.build.getResult())
log.println(' Decorating the following upstream builds:')
//log.println(manager.build.getUpstreamBuilds()) // prints "[:]", so using this to get the upstream Builds doesn't work
for (Cause cause : manager.build.getCauses()) {
for (Project project : projects) {
if (cause.toString().contains(project.getName())) {
int no = cause.getUpstreamBuild()
Build usb = project.getBuildByNumber(no)
log.println(" ${usb}")
usb.getActions().add(GroovyPostbuildAction.createShortText(
'SNAPSHOT deployed on DEV', 'black', 'gold', '1px', 'black'));
usb.getActions().add(GroovyPostbuildAction.createInfoBadge(
'SNAPSHOT deployed on DEV'))
usb.getActions().add(GroovyPostbuildAction.createBadge(
'star-gold.png', 'SNAPSHOT deployed on DEV'))
}
} // for (projects)
} // for (causes)
log.println(' ----------------')
Note:
This adds badges regardless of the build result but I'm confident that you can add the appropriate if easily. For removing badges see Groovy Postbuild Plugin's page.
