Meta-packages not supported (POM-only)

[genesio-systemlogic]

Hello, I am testing IKVM with Maven references in a .NET 6 project.

This reference gives me an error at build time:

<MavenReference Include="tika-parsers"> <GroupId>org.apache.tika</GroupId> <ArtifactId>tika-parsers</ArtifactId> <Version>2.6.0</Version> <Type>pom</Type> </MavenReference>

IKVM.Maven.Sdk.targets(96, 9): ArtifactNotFoundException: Could not find artifact org.apache.tika:tika-parsers:jar:2.6.0 in central (https://repo1.maven.org/maven2/)

The package I am trying to use is the following:
https://mvnrepository.com/artifact/org.apache.tika/tika-parsers/2.6.0

What am I doing wrong?

What is Type POM?

[genesio-systemlogic]

I am no Java expert but it looks like a "meta-package" with just pointers to other packages

I get the same error without the pom element

Was this error on a Windows build machine?

[genesio-systemlogic]

yes it is a windows 11 dev machine

Yeah. Not totally sure how this is supposed to work in Maven.... but it doesn't appear we support "modules". Which are these aggregator POMs. Not sure if Maven is supposed to allow dependencies towards them, or if they're only for build time.

Either way, you can reference each module independently.

So it looks like we could probably add this. But some changes would need to be made. We feed MavenReferences into Aether to resolve, but we default 'extension' to JAR, because what else would we expect to receive. Would have to see whether we can set that to NULL, and have it be smart enough to decide upon a JAR if available. Not sure how that's supposed to work. We can't know whether it's a meta-package until AFTER we resolve..... so how do we resolve it before we know? Will need to fool around with it to see what happens.
