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)
