I have a gradle which downloads a zip file. Then I unpack the file (this contains a jar and its dependencies). The version of the file is in a text file, which I read out. Now I want to put the library in an ivy repository.  
How do I get it to set the version only before the actual publish?

```
Version: unspecified wurde ermittelt!
:downloadfile
:generateDescriptorFileForIvyPublication
:publishIvyPublicationToIvyRepository
:publish

publications {
	ivy(IvyPublication) {
		descriptor.status = "release"
		module "ikit"

		File file = new File (buildDir, "revision.txt")
		if(file.exists()) {
			file.eachLine {
				revision it
			}
		} else {
			logger.error "File doesn't exists!"
		}

		descriptor.withXml {}
     }
  }
```
