In the case of multi-project builds, the `file()` method will always turn relative paths into paths relative to the current project directory, which may be a child project.

=== Using `Project.getRootDir()`

                    project.getGroupId(), project.getArtifactId(), project.getVersion(), null, project.getPackaging());
            project.setArtifact(projectArtifact);

            // only set those on 2nd phase, ignore on 1st pass
            if (project.getFile() != null) {
                Build build = project.getBuild().getDelegate();
                project.addScriptSourceRoot(build.getScriptSourceDirectory());

=== Potential breaking changes

 * Non-Java projects that have a <<declaring_dependencies.adoc#sub:project_dependencies,project dependency>> on a Java project now consume the `runtimeElements` configuration by default instead of the `default` configuration.
+
To override this behavior, you can explicitly declare the configuration to use in the project dependency.
For example: `project(path: ':myJavaProject', configuration: 'default')`.
