Using -SNAPSHOT version for non release builds together with zip task

[Peter Voss]

Hi,

the user guide has a nice example on how to generate different version  
number for release build by evaluating the taskGraph. How can I use  
this together with Zip tasks? I need the version number in my zip  
task, but the task gets fully evaluated and all variables expanded on  
task creation. It's too late to change the project version number  
after that.

Here is a minimal example:

build.gradle:
usePlugin "java"

task release(dependsOn: 'dist') << {
     println "Created release for version ${version}"
}

task dist(type: Zip) {
     println "Created zip task with version $version"
     zipFileSet(dir: projectDir, prefix: "$name-$version") {
         include("build.gradle")
     }
}

gradle.taskGraph.whenReady {taskGraph ->
     if (taskGraph.hasTask(':release')) {
      version = "1.0"
     } else {
      version = "1.0-SNAPSHOT"
     }
     println "Version set to $version"
}

When I run gradle dist, I get the following output:
Created zip task with version unspecified
Version set to 1.0-SNAPSHOT
:dist

BUILD SUCCESSFUL

You can see that the version numbers get set too late. The zip file  
that is created is: build/distributions/myproject-unspecified.zip
Any ideas?

Thanks,
--Peter

The zipFileSet is the problem. In 0.8 it does early evaluation. This  
is fixed in trunk where it evaluates late.
As a work around you can do:

task dist(type: Zip) {
     println ....
     doFirst { task ->
        task.zipFileZet ...
}

Thanks for this workaround. I have used the zip ant task to work  
around this. I will move back to gradle's zip task type as soon as I  
have updated gradle.
