[pom editor question] How does the pom editor resolve the local repository to analyze dependencies?

[rhoehener]

I ran maven in the cmd prompt once with a custom local repo parameter (-Dmaven.repo.local=reactor-repo), and now the m2e pom editor also uses that repo for dependency analysis and navigation. I get many warnings that plugins cannot be found.

Sometimes I use a custom user settings file in the maven settings to point to (yet another) custom local repo, but currently I have no special configuration (see screenshot).

I tried search for 'reactor-repo' in the eclipse workspace and plugin folders but didn't find anything.

Could you help me debug how m2e resolves the local repository?

Have you tried "update maven project" with the force option?

[rhoehener]

Yes, this is always the first thing I do: Restart eclipse, then select all projects and update maven projects with force update snapshots.

I have also tried deleting all .lemminx-maven folders I could find. It looks to me as if m2e keeps it's own repository there? It looks like it creates that folder next to wherever the 'currently identified local repository' is.

[rhoehener]

I tried to reproduce it with a simple new workspace but no luck so far. But all my real big workspaces are messed up as soon as I start switching between custom user settings and different local repos.

It would already help a lot if I could find the place where m2e stores the location of the local repository (I assume it is some kind of stale cache).

The LemMinX Language Server and its extension for Maven get informed of the path to settings file configured via preferences during their initialization, see

m2e-core/org.eclipse.m2e.editor.lemminx/src/org/eclipse/m2e/editor/lemminx/InitializationOptionsProvider.java

Line 29 in a1dad44

Optional.ofNullable(config.getGlobalSettingsFile()).ifPresent(globalSettings -> mavenSettings.put("globalSettings", globalSettings));

.
The LemMinX extension is supposed to receive it and process it, in org.eclipse.lemminx.extensions.maven.MavenLemminxExtension.initMavenRequest() .

If you want to debug the running language server, please see https://github.com/eclipse-wildwebdeveloper/wildwebdeveloper/blob/master/TIPS_and_FAQ.md#attach-a-debugger-to-the-xml-language-server-process

Thank you Mickael, I will have a look!
