gradle to create multiple war files from folders

Question

My Gradle project doesn't contain any classes or other configurations. It contains a folder called ExternalLibs containing other folders. I need to create a war file for each folder present in ExternalLibs and place it in lib folder.

Thanks for the help.

Folder structure:

 Project Root
   |-- ExternalLibs
         |-- analyst
         |-- storageService
         |-- retrievalService

Exepcted output:

 Project Root
   |-- lib
        |-- analyst.war
        |-- storageservice.war
        |-- retrievalService.war

You can use a task of type Zip , since War archive is a Zip with a fancy extension. You have to create a task per War , but you can automate it by creating tasks dynamically:

List folders = new File(projectDir, "ExternalLibs").listFiles();
folders.each { dir ->
    task "zip${dir.name}"(type: Zip) {
        from dir
        include '**/*'
        destinationDir new File("$projectDir/lib")
        archiveName "${dir.name}.war"
    }
}

To run all tasks at once, you can create a task that depends on all of them:

task allZips { }
allZips.dependsOn tasks.withType(Zip)
