Martin Todorov commented on MINDEXER-49:
----------------------------------------
[~paleozogt],
My understanding is that the {{maven-metadata.xml}} files are not used during
the indexing. Also, based on your reasoning, if you have artifact files on the
file system and these are (for some reason) not defined in the
{{maven-metadata.xml}}, then the artifacts will not be indexed. Theoretically,
this can be done the way you're proposing, but it will slow down the
re-indexing significantly when used at a much larger scale than just a few
files.
> 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
> 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.
