about that if you agree? Thanks!

> Since I know that ComparableVersion was brought to Maven from 
> versions-maven-plugin, it turns out the bug described here:
> https://github.com/mojohaus/versions-maven-plugin/issues/744
> also exists in maven, at least in 3.8.3.
> According to the maven version spec, versions containing a qualifier should 
> be treated as less major than the same versions without the qualifier. 
> Currently it's only the case for a few "standard" qualifiers, e.g. "-rc*", 
> "-alpha", etc.
> However, it looks like "2.3-pfd" is deemed less major than "2.3".
> {code:java}
>     @Test
>     public void testComparableVersionWithCustomQualifier()

>         assertThat( new ComparableVersion( "2.3" ).compareTo( new 
> ComparableVersion( "2.3-pfd" ) ),
>                 greaterThan( 0 ) );
