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