Adding Jenkins file to compile with Gradle

Question

Adding Jenkins file to compile with Gradle

I have a Gradle build with source settings configured like so:

sourceSets {
    main {
        groovy {
            srcDir 'src'
        }
    }
}

I have Jenkinsfile

in the root of a project that I would like to compile so that I can detect invalid Groovy before it merges into the master branch and breaks the Jenkins build.

How can I add this single file to my Gradle project source kits for compilation? How can I guarantee that Gradle will compile it even though it didn't get the extension .groovy

?

You can add additional ones sourceSet

like this:

sourceSets {
    jenkins {
        groovy {
            srcDir "$projectDir"
            include "JenkinsFile"
        }
    }
    main {
        groovy {
            srcDir 'src'
        }
    }
}

However, the problem is that you won't be able to compile the text file as Groovy. However, you can create a task to create, compile and delete a new file .groovy

containing the contents of the Jenkins file before compiling groovy. The final build file doing this will look like this:

apply plugin: 'groovy'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

sourceSets {
    jenkins {
        groovy {
            srcDir "$projectDir"
            include "JenkinsFile.groovy"
        }
    }
    main {
        groovy {
            srcDir 'src'
        }
    }
}

task(createGroovyFile) {
    File jenkinsFile = new File("$projectDir/JenkinsFile")
    File groovyFile = new File("$projectDir/JenkinsFile.groovy")
    if(groovyFile.exists()) groovyFile.delete()
    groovyFile.newDataOutputStream() << jenkinsFile.readBytes()
}

task(deleteGroovyFile, type: Delete) {
    File groovyFile = new File("$projectDir/JenkinsFile.groovy")
    delete(groovyFile)
}


compileGroovy.dependsOn deleteGroovyFile
deleteGroovyFile.dependsOn compileJenkinsGroovy
compileJenkinsGroovy.dependsOn createGroovyFile

configurations {
    jenkinsCompile.extendsFrom compile
}

dependencies {
    compile   "org.codehaus.groovy:groovy-all:2.4.10"
}
