Body

While loading a project to test the jakartaEE support I noticed this issue:

The projects has a parent pom, that is loaded from an internal repository. I configured my settings.xml, so that this repository is only added if I run with the corresponding profile loaded. By default the special profile is not loaded and thus the project gets loaded without the right repository present.

This situation can be simulated like this:

  1. Get the reproducer code: reproduzer.zip
  2. Unzip it
  3. Run mvn install from the demo repository
  4. Simulate, that the artifact comes from a remote repository, that is currently unavailable (this assumes, that you are on a Unix-like System: 
    echo "demo-1.pom>demo=" > $HOME/.m2/repository/demo/demo/1/_remote.repositories`
    To my understanding this tells the system, that the artifact comes from the repository with id demo (I used my problematic artifact as basis for this hypothesis)
  5. Build NetBeans master from source
  6. Run ant tryme
  7. Open the brokenmavenproject maven project

You can observe on the CLI output:

     [exec] [Maven project reloading] INFO org.eclipse.aether.internal.impl.DefaultArtifactResolver - Artifact demo:demo:pom:1 is present in the local repository, but cached from a remote repository ID that is unavailable in current build context, verifying that is downloadable from [central (https://repo.maven.apache.org/maven2, default, releases)]

The UI becomes unresponsive, CPU usage as reported by VisualVM is around 10%, with spikes to 30%, heap usage is steadily growing. The Threaddump also seems to lead to maven.

I reached the conclusion, that #5978 is the offending commit, because I checked the commits related to maven and build that commit and its predecessor. The problem is reproducible with the commit and not without it.

As verifier I build master, reproduced the problem and reverted ad99e85 and could not reproduce it anymore.

@sdedic could you please have a look at this? Could there be a loop, that causes, the "broken" project to load in a loop and explain this problem?

Yes, I need to refine the check for reported, but existing artifact it seems.

@sdedic can you estimate whether you can look into this before freeze on next tuesday? If that is a problem, we should consider reverting the problematic change and reapply a fixed version once it is ready. Currently the reposity is clean enough, that a straight revert is possible.

The point here was to NOT prime if another priming build actually downloaded the artifact. But in this case artifact exists physically, but proper maven build actually treats it as missing / need to download.

I have half-working better test - but it requires a subtle change to Embedder configuration (replacing SimpleLocalRepository with EnhancedLocalRepository that does _remote_repositories.properties checks) that I am not entirely confident about. And found yet another bug that actually causes the loop (the project should have been parsed at most twice). Fixing the bug alone (which is a local change) should break the loop.
