如何在Jenkins Groovy管道中调用Ant

Question

I have created a Jenkins Pipeline job. In this job I want to do the build using Ant. I have configured the Ant variable in Manage **Jenkins > Global Tool Configuration** as Ant1.9.1= D:\\path_to_hybris\\hybris\\bin\\platform\\apache-ant-1.9.1 .

In a freestyle jenkins Job, I know that the build.xml location can be specified as in the below screenshot:

but I am unable to understand how to specify the ant groovy script beyond this point, especially where can we mention the path to build.xml file:

def antHome = tool 'Ant1.9.1'
????

Answer 1

You can try this:

def antVersion = 'Ant1.9.1'
withEnv( ["ANT_HOME=${tool antVersion}"] ) {
    sh '$ANT_HOME/bin/ant target1 target2'
}

Under Windows this would look like this (I didn't test it though):

def antVersion = 'Ant1.9.1'
withEnv( ["ANT_HOME=${tool antVersion}"] ) {
    bat '%ANT_HOME%/bin/ant.bat target1 target2'
}

This assumes that you have Ant configured in Jenkins with name 'Ant1.9.1'.

Answer 2

you can use ant wrapper in Jenkins`s pipeline groovy script.

withAnt(installation: 'LocalAnt') {
// some block
   sh "ant build"
//for windows 
   bat "ant build"
}

Remember to configure the ant tool in the Jenkins "Global Tool Configuration" with the same name "LocalAnt".

Answer 3

I needed this multiple times within the same Jenkinsfile that needs to be executed on both linux and windows agents so I created a method for it.

You can call ant like this

callAnt("-v -p")

if you add this method definition to your jenkinsfile

def callAnt(String Parameters) {
    if (isUnix()) {
        env.PATH = "${tool 'ant'}/bin;${env.PATH}"
        sh "ant ${Parameters}"
    }
    else {
        env.PATH = "${tool 'ant'}\\bin;${env.PATH}"
        bat "ant ${Parameters}"
    }
}
