I'm using Jenkins for my Android app builds. On every build, I get some info, like build number, etc...

I'm searching a way to read the versionName value of in the build.gradle when Jenkins build the job. I know we can get the buildNumber with the $BUILD_NUMBERenv variable, but how to get the versionName?

You could do this by adding an Execute Shell step which determines the versionName, and exporting it as an environment variable using the EnvInject Plugin.

Assuming your build.gradle contains:

versionName = myname

You can add this script:

v=$(cat build.gradle  | grep versionName | awk '{print $3}')
echo MY_VERSION_NAME=${v} > env.properties

  • Yeah, really great!. What's the trick if I just wanna get the version which is between "". For example versionName = "1.0.0", just wanna 1.0.0 – ejay May 23 '17 at 15:40

    @ejay you can simply delete the `"` characters using **tr**: `v=$(cat build.gradle | grep versionName | awk '{print $3}' | tr -d \" )` – sgargel May 23 '17 at 16:06
  • Perfect! Thanks! – ejay May 23 '17 at 19:35
  • Shouldn't this be '{print $2}' since we're trying to print the version name which is the second part of the string. Kinda like `versionName "3.0.0"` – 11m0 Mar 23 '18 at 04:44
  • In my `build.gradle` there is `=` between variable and value. – sgargel Mar 23 '18 at 06:41

A better way to do this is add a "printVersion" task in build.gradle. app/build.gradle

task printVersion{
  doLast {
    print android.defaultConfig.versionName + '-' + android.defaultConfig.versionCode
  }
}

Test it with: ./gradlew -q printVersion 

1.8-13

Then in jenkins pipeline, add a stage after git:

   stage('printVersion') {
        def versionInfo = sh (
            script: './gradlew -q printVersion',
            returnStdout: true
        ).trim()
        echo "VersionInfo: ${versionInfo}"
//set the current build to versionInfo plus build number.
        currentBuild.displayName = "${versionInfo}-${currentBuild.number}" ; 
   }

Example: gradle properties | grep "version" | awk '{print $2}'

On jenkins:

def versionInfo = sh (
  script: "gradle properties | grep 'version' | awk '{print $2}'",
  returnStdout: true
).trim()
println versionInfo
