032/// A special [JarBuilder] that generates a sources jar following
033/// the maven convention.
034///
035///   * The content of the jar is obtained by requesting [FileTree]s
036///     with [JavaSourceFile]s from the project's suppliers.
037///
038///   * The name of the jar is set to `<artifactId>-<version>-sources.jar`,
039///     where `<artifactId>` is the value of the project's property 
040///     [MvnProperties#ArtifactId] with a fallback to the project's name.
041///     `<version>` is the value of the project's property
042///     [Project.Properties#Version].
