How to enable SNAPSHOT dependencies?

[kavink]

How can we pass flags to gradle release plugin which is a requirement https://github.com/townsfolk/gradle-release , i.e. if i would like to enable SNAPSHOT dependencies, how can i do it ?

I researched the possibility of external configuration of failOnSnapshotDependencies property. The result is:

1. townsfolk/gradle-release does not support defining it's extension properties via project properties or system properties.
2. Gradle does not support passing extension properties via command line or via GradleBuild task.

The only possible solution at the moment is to set failOnSnapshotDependencies within "build.gradle" of the concrete git repository:

release {
  failOnSnapshotDependencies = false
}

is it possible to inject into build.gradle temporarily ? Not committing any changes, just using it for building ?

I will think on it.

Now it is possible to configure ARF that way, that it allows SNAPSHOT dependencies:

multiproject {
  git baseDir: 'upstream_repos', {
    project name: 'project1', {
      releaseVersion(/(\d+)([^\d]*$)/, { null })
    }
    project name: 'project3'
    project name: 'project2', dependsOn: [ 'project1', 'project3' ], failOnSnapshotDependencies: false
  }
}

in this example project2 allows snapshot dependencies, while other projects don't.

failOnSnapshotDependencies can be defined globally:

multiproject {
  failOnSnapshotDependencies = false
  git baseDir: 'upstream_repos', {
    project name: 'project1', {
      releaseVersion(/(\d+)([^\d]*$)/, { null })
    }
    project name: 'project3'
    project name: 'project2', dependsOn: [ 'project1', 'project3' ]
  }
}

Note new special syntax in releaseVersion of project1: { null }. It means that code will be released with current version number, without modifications. For example, if project1 has version 2.0-SNAPSHOT, it will be released as 2.0-SNAPSHOT.

I did not understand the second part about { null } when is that needed ?

when we need to release with snapshot version.
