Gradle Zip Task: Add Dynamically Generated File

I have a gradle build script in which I'm using the 'Zip' task to generate a zip archive directly from a source directory.

In addition to copying over all the files inside the source directory structure into the zip archive, I'm looking for a way to include a dynamically generated file that's not in the source directory.

Do you guys know how I can do this?

Here's pseudo code of what I want to do:

task('archive', type: Zip) {
  ...
  from 'source'
  newFile('dynamically-generated.txt', 'dynamic file content')
}

And here are the source and destination structures:

[i71178@bddev01-shell01 ~]$ tree source/
source/
├── file1.txt
├── file2.txt
└── file3.txt

0 directories, 3 files
[i71178@bddev01-shell01 ~]$ unzip -l destination.zip
Archive:  destination.zip
  Length      Date    Time    Name

---------  ---------- -----   ----
        0  02-26-2016 16:56   source/
        0  02-26-2016 16:56   source/file2.txt
        0  02-26-2016 16:56   source/dynamically-generated.txt
        0  02-26-2016 16:56   source/file1.txt
        0  02-26-2016 16:56   source/file3.txt
---------                     -------
        0                     5 files

I have managed to achieve it quite easyly on Gradle 6.6.1 by just creating the file in the from section.

distributions {
  main {
    contents {
      into("/") {
        from {
          if (!buildDir.exists()) {
            buildDir.mkdir()
          }
          def f = new File("$buildDir/all")
          f.text = "project_version: ${project.version}\n"
          f
        }
      }
      ...
    }
  }
}

btw. I think $buildDir is safer than /tmp

This is what I ended up doing:

subprojects {
  apply plugin: 'myPlugin'

  //The 'build' task is set up by the plugin
  build {
    //Customization to keep consistent with artifacts being currently generated.
    doFirst {
      new File(getTemporaryDir(), 'artifact-fullname.txt').text = "${project.name}-${project.version}\n"
    }
    archiveName = "${project.name}.${project.build.extension}"
    from getTemporaryDir()
  }
}

Thanks!

Combining my comments above and your getTemporaryDir comment:

task generateThenZip()<<{
    def tempDir = getTemporaryDir()
    newFile("$tempDir/dynamically-generated.txt", 'dynamic file content')

    zip{
        from 'source'
        from tempDir
    }
}
