Question

EDIT:
I am trying to run these two commands and get these results in a gradle subproject…

gradle assemble -> databus-Developer-Build.zip
gradle -DmyVersion=1.0.2 -> databus-1.0.2.zip

Currently, my output is databus-null.zip IF I use $version instead of $myVersion. When using $MyVersion, I get the error “myVersion is not a property on that task”. 🙁 :(.

EDIT

So, trying out the first answer completely failed with “Could not find property $myVersion on task ‘:webserver:myZip”

NOTE: I am trying to do this in a subproject right now. Here is the subproject gradle code…

project(':webserver') {
    project.ext.genLibDir = file('lib')
    project.ext.fixedLibDir = file('../master/libother')

    dependencies {    
        compile project(':master')
        compile fileTree(dir: '../webserver/lib', include: '*.jar')
        compile fileTree(dir: '../webserver/play-1.2.4/framework/lib', include: '*.jar')
        compile fileTree(dir: '../webserver/play-1.2.4/framework', include: 'play-*.jar')   
    }

    task deleteJars(type: Delete) {
        ext.collection = files { genLibDir.listFiles() }
        delete ext.collection
    }
    task copyJars(type: Copy) { 
        from(configurations.compile) {}
        from(fixedLibDir) {}
        into genLibDir
    }
    copyJars.dependsOn('deleteJars')
    classes.dependsOn('copyJars')

    task myZip(type: Zip) {
        archiveName "dashboard-"+$myVersion+".zip"
        from('..') {
            include 'webserver/run*.sh'
            include 'webserver/app/**'
            include 'webserver/conf/**'
            include 'webserver/play-1.2.4/**'
            include 'webserver/public/**'
        }
    }

    assemble.dependsOn('myZip')

    //playframework has it's own generation of .classpath and .project fils so do not 
    //overwrite their versions.  NEED to call "play.bat eclipsify" here...
    task eclipse(overwrite: true) {
    }


    gradle.taskGraph.whenReady {taskGraph ->
        if (taskGraph.hasTask(assemble) && myVersion == null) {
            myVersion = 'Developer-Build'
        }
    }
}

thanks,

ok, the correct answer is doing something like this…(add this to allprojects section)..

   if (project.hasProperty('myVersion')) {
     project.ext.xVersion = project.myVersion
   } else {
     project.ext.xVersion = 'Developer-Build'
   }

and interestingly enough this below one does NOT work because ‘version’ seems to be some sort of reserverd property and is set to unspecified on startup…

   if (project.hasProperty('version')) {
     project.ext.xVersion = project.version
   } else {
     project.ext.xVersion = 'Developer-Build'
   }

Seeing as version seems to be a reserved property, it is most likely used in publishing artifacts so the best solution then maybe the following

   if (project.hasProperty('myVersion')) {
     project.version = project.myVersion
   } else {
     project.version = 'Developer-Build'
   }

and the automated build passes in myVersion and developers of course don’t.
