Maven: Resolve artifactId properties before downloading versions

[sghill]

What's changed?

Support changing managed maven dependencies with artifactIds that include properties.

What's your motivation?

Jenkins has moved to a model where a bom is now defined like

<artifactId>bom-${jenkins.baseline}.x</artifactId>

This breaks the org.openrewrite.jenkins.ModernizePlugin recipe. Attempting to use an artifactId with a property fails to resolve:

Caused by: org.openrewrite.internal.RecipeRunException: java.lang.IllegalArgumentException: Illegal character in path at index 67: file:///home/sghill/.m2/repository/jakarta/activation/jakarta.acti${partial.arti}-api/maven-metadata.xml

jenkinsci/archetypes#737

Anyone you would like to review specifically?

@timtebeek and I briefly talked about this on OSS Slack.

Have you considered any alternatives or workarounds?

I made an attempt to fix this in the MavenPomDownloader in sghill@941e1ee. It didn't work because the set of resolved poms through this codepath is always empty.

Since this is valid maven, I think it'd be nice if this were universally supported instead of just fixed in this one recipe. I'm not quite sure how to go about making it more universal.

Any additional context

This is more for discussion than an implementation I feel strongly about. My ideal end state is for the ModernizePlugin recipe to compose these building blocks to extract a jenkins.baseline property and use it in multiple places, just like the updated plugin archetype.

Checklist

• I've added unit tests to cover both positive and negative cases
• I've read and applied the recipe conventions and best practices
• I've used the IntelliJ IDEA auto-formatter on affected files

In fact such placeholder cause other issues when some recipes

When testing

type: specs.openrewrite.org/v1beta/recipe
name: io.jenkins.tools.pluginmodernizer.UpgradeParentVersion
recipeList:
  - org.openrewrite.maven.UpgradeParentVersion:
      groupId: org.jenkins-ci.plugins
      artifactId: plugin
      newVersion: 4.X

I got some result that OpenRewrite is moving some dependency on dependencyManagement even if they are managed by the pom. Probably because the resolution with placeholder doesn't happen correctly
