 here's what I do currently in the netbeans part of the mavenide project to
 find the relevant subprojects/sibling projects. I check if the user has
 defined the maven.multiproject.includes property in any of his properties
 files for the current project. if yes. then I'm able to find projects that
 can be offered to be opened together with the current project.
 problems with the current solution are:

// do not attempt to find projects when the plugin is applied just to generate accessors
if (project.name != "gradle-kotlin-dsl-accessors" && project.name != "test" /* remove once wrapper is updated */) {
    dependencies {
        testFixturesApi(project(":internal-testing"))
        // platform
        testFixturesImplementation(platform(project(":distributions-dependencies")))

                sortedProjects.stream().noneMatch(project -> result.getBuildSummary(project) instanceof BuildSuccess);

        if (hasNoSuccess) {
            return Optional.empty();
        }

        List<String> remainingProjects = sortedProjects.stream()
                .filter(project -> result.getBuildSummary(project) == null
                        || result.getBuildSummary(project) instanceof BuildFailure)
