Maven Plugin that provides alternative repository
Hi,
I'd like to create a plugin that gets notified if maven tries to
download an artifact but does not find it in any of its configured
repositories. Is this possible to archive by a maven plugin? If yes
what is the best starting point for this?
My own search for this have not revelead any usefull information
beside basic maven plugin tutorials that do not cover this specific
case.

IIRC, it won't work from pom.xml, but should work from extensions.xml
(Maven 3.3+). It definitely works when you drop your extension JAR into
lib/ext/ directory.

Dependency resolution must work before effective model (POM) is
constructed - to resolve <parent> references. So you must find another
way of configuring your extension.

So extensions for WorkspaceReader can't be used like described here[1]
inside the pom.xml?
Does that mean I have to put my extension in the maven classpath to
make it work?
If I do tis, is it still possible to configure the Extension inside
the pom or has it to be done by system-properties?

When POM is parsed, workspace reader is already loaded, so it would be
too late. So it needs to be loaded by an extension.

Eclipse M2E is one example. Another one is XMvn, which uses workspace
reader to resolve dependencies from system repository (not in Maven format):

I think this would modify the overall Maven behaviour and you would therefore have to implement this as an extension rather than as a plugin. Fyi. we have such an extension that modifies usage of the local repository already within Takari.
Use it as inspiration..

WorkspaceReader functionality is or is not a thing that can be set in
pom.xml files?
Are there any examples in public that use WorkspaceReader in use to
source a dep from outside of maven central (or the projects sibling
modules)?

This should be possible by providing WorkspaceReader implementation -
@Component( role = WorkspaceReader.class, hint = "ide" )
Note that Maven tries resolution from workspace *before* repositories -
workspace reader has priority lower than reactor, but higher than remote
repos known to Maven.

Hi,
thanks for your reply. I'd like to make artifacts avaiable to maven
via <dependency> that are located in a repository with a format that
maven does not understand.
Even though if I would have the group+artifactid+version I can locate
that artifact there.
So the idea is to add a plugin to the build that gets asked whenever
maven does not find an artifact in any of its default sources so I can
give it a try to find it in my special repro.
Even though it might be possible to convert the other repro to a maven
structure, this means I have to download all artifacts from this,
upload them again and repeat the stepp an each change, thats why I'd
like to find a way to use the repro directly.

My first question is: What is the background of this question? Means
what are you trying to solve? What kind of problem do you have?
