> M2GavCalculator does not parse GAV correctly for classifiers with dots
> ----------------------------------------------------------------------
>
> Key: MINDEXER-49
> URL: https://issues.apache.org/jira/browse/MINDEXER-49
> Project: Maven Indexer (Moved to GitHub Issues)
> Issue Type: Bug
> Affects Versions: 4.1.1, 4.1.2
> Environment: all
> Reporter: René Zanner
> Priority: Critical
>
> When having a classifier with dots (classifier.with.dots) and an extension
> with or without dots (e.g. tar.gz), the calculation of Gav changes classifier
> and type/extension to something clearly not intended:
> || ||Attached artifact definition||M2GavCalculator result||
> ||classifier|classifier.with.dots|classifier|
> ||extension/type|tar.gz|with.dots.tar.gz|
> The problem seems to be located in lines 136ff, 175ff *and* 216ff (do you
> have a code duplication issue as well? ;-) ):
> {code}
> int nExtPos = tail.indexOf( '.' );
> ...
> ext = tail.substring( nExtPos + 1 );
> classifier = tail.charAt( 0 ) == '-' ? tail.substring( 1, nExtPos ) : null;
> {code}
> This code assumes that the classifier ends at the first dot in the "tail"
> (which is everything after the version number).
> Since Maven allows dots in classifiers _as well as in extensions_, the
> parsing has to be made more intelligent. So, it is not enough to just turn
> the parsing around and use the part after the last dot as extension and
> before it as classifier (that's why I used the 'tar.gz' extension in my
> example above).
> I do not have a solution for this except checking for well-known extensions
> (tar.gz, xml, jar, zip, a.s.o.) and build the classifier/extension parsing
> around it.
