不合法的版本号会抛出SemverException异常。

try {
    Semver semver1 = new Semver("a.b.c");
} catch (SemverException e) {
    throw new RuntimeException(e);
}

输出

Caused by: com.vdurmont.semver4j.SemverException: Invalid version (no major version): a.b.c
    at com.vdurmont.semver4j.Semver.<init>(Semver.java:61)
    at com.vdurmont.semver4j.Semver.<init>(Semver.java:20)
    at org.example.SemverTest.main(SemverTest.java:24)

        Integer major = semver.getMajor();
        Integer minor = semver.getMinor();
        Integer patch = semver.getPatch();
        String build = semver.getBuild();
        boolean greaterThan = semver.isGreaterThan("1.3.0");
        boolean lowerThan = semver.isLowerThan("2.0.0-beta");

        System.out.println("greaterThan#" + greaterThan);
        System.out.println("lowerThan#" + lowerThan);
    }

}
