  <description>Maven is a project development management and
    comprehension tool. Based on the concept of a project object model:

        validateStringNotEmpty("packaging", problems, Severity.ERROR, Version.BASE, m.getPackaging(), m);

        if (!m.getModules().isEmpty()) {
            if (!"pom".equals(m.getPackaging())) {
                addViolation(
                        problems,
                        Severity.ERROR,
                        Version.BASE,
                        "packaging",
                        null,

To create a Gradle distribution from the source tree you can run either of the following:

    ./gradlew :distributions-full:binDistributionZip

This will create a minimal distribution at `packaging/distributions-full/build/distributions/gradle-<version>-bin.zip`, just what's needed to run Gradle (i.e. no sources nor docs).

            if ("bom".equals(p.getPackaging())) {
                LOGGER.info(
                        "The packaging attribute of the '{}' project is configured as 'bom' and changed to 'pom'",
                        p.getName());
                p.setPackaging("pom");
            }
        }
