Jenkins useful tips

jenkins tips

1) Groovy script to change build display value

// get current build
def build = Thread.currentThread().executable

// get new value for build
def newBuildName = build.getEnvironment().get('newDisplayVersionj')

// set new display name
try {
    if (newBuildName) {
      build.displayName = newBuildName
      println "Build display name is set to ${newBuildName}"
   }
} catch (MissingPropertyException e) {} 

2) To find out which jobs are using which plugins
    Find out the string which we can grep for in config.xml. Mostly it can be xml node name or attribute
 
    e.g. In case of Job DSL plugin i can grep for pattern# plugin=\"job-dsl*
    grep --include=config.xml -rnw '#JENKINSHOME/jobs/' -e "plugin=\"job-dsl*"
