tycho Inject content of settings.xml into the artifact resolution.

When downloading Maven artifacts from e.g. a private repository, Tycho needs to authenticate itself as a valid user, using the credentials provided in the settings.xml file.

Otherwise the request most likely fails with a 401 - Unauthorized.

As context: We deploy some of our artifacts to a local Nexus. Currently, anonymous access is enabled, hence why Tycho can download them as dependencies for our product without problem. But at some point, we want to get rid of it, due to security requirements.

Tycho already supports authenticated access for p2 repositories, but for Maven repositories, the content of the settings.xml file is ignored.

The pull request is currently at a state where Tycho successfully downloads the jars, but then fails when downloading the corresponding pom during the compilation phase. Does anyone have an idea what I'm missing?

@pzi-dsa this looks very interesting. Do you think you can add an integration test for this? There are already some for maven and updatesite authentication that might could be used as a basis?

Jul 02 '22 16:07 laeubi

I've tried setting up an integration test similar to PasswordProtectedP2RepositoryTest. However it seems mocking a m2 repository is a little bit more complicated than a p2 repository. I'm also at a loss at how to proceed with the actual implementation. Authentication works when adding the repository directly to the pom, but fails if it is added to the location of the target platform.

So clearly there is something native Maven does, that Tycho doesn't. I just can't figure out what... :/

Given that it works in m2e, I also looked at how it's done there. But there everything is managed by the IMaven interface, which also solves this via the call of injectAuthentication(...).

Authentication works when adding the repository directly to the pom, but fails if it is added to the location of the target platform.

I must confess that I assumed there is nothing to do specially as we use the maven resolver system. The only think I can think of is that somehow the ID is messed up and maven uses the ID to find the authentication...

Jul 05 '22 13:07 laeubi

@pzi-dsa if there is a public available example I can also try to take a look, but I have no password-protected setup at hand here to test...

Jul 06 '22 07:07 laeubi

I think I managed to get the integration test running. It turned out the GAV in the target platform didn't match the artifact in the repository.

On the master, I get the following entry in my .m2 repository:

#NOTE: This is a Maven Resolver internal implementation file, its format can be changed without prior notice.

And on my branch, the following:

#NOTE: This is a Maven Resolver internal implementation file, its format can be changed without prior notice.

http\://localhost\:64875/foo/.lastUpdated=1657098516637

In the second case, the jar is also successfully stored in my local repository. Which is exactly what I was hoping for. However, I have yet to reproduce the second error. i.e. I still need to understand what's causing Tycho to download the pom file.

Tycho injects the Maven artifacts into the model, and then maven tries to download them. In general, they should already be available locally then, but for the case of password-protected mirrors there might be a flaw.

There is also some ongoing work to improve this. Can you explain what "It turned out the GAV in the target platform didn't match the artifact in the repository." mean here?

Jul 06 '22 10:07 laeubi

Can you explain what "It turned out the GAV in the target platform didn't match the artifact in the repository." mean here?

The mock repository I created for the test only contains a single artifact, test:jakarta.inject-api:1.0. But in my target file, I was referencing test:jakarta.inject:1.0. So the test failed because it couldn't resolve the target platform, which I mistook as having misconfigured the Maven repository.

It has nothing to do with the problem at hand, just a mistake on my side.

Jul 06 '22 10:07 ghost

I think I managed to adapt the test case in such a way that it reproduces the stacktrace from my second comment. They are not identical, but both lead to the same cause, the inability to download the pom file from the local Maven repository, as shown in the lastUpdated file:

#NOTE: This is a Maven Resolver internal implementation file, its format can be changed without prior notice.

If I set this draft to "Ready for review", it should start the test suite, right? Hopefully it will then fail with the same error.

Jul 06 '22 13:07 ghost

@pzi-dsa is this the error you are expecting?

Jul 07 '22 05:07 laeubi

@laeubi I think that's exactly it!

Jul 07 '22 06:07 ghost

Alright, I think your previous code changes are not related to this failure and it would wonder me if they make anything better as we should inherit the maven settings but the maven resolution itself has a problem here, so if you like the starting point for debugging should be org.eclipse.tycho.core.maven.MavenDependencyInjector.injectMavenDependencies(....) where we try to inject the repositories from the target into the model here:

https://github.com/eclipse/tycho/blob/bb190b4f39df1a55012b89f45ee9adba31a9f70a/tycho-core/src/main/java/org/eclipse/tycho/core/maven/MavenDependencyInjector.java#L77-L94

this should be the first place to check if something went wrong here (e.g. wrong/missing ids, no repositories injected at all / ...) and also a breakpoint at org.apache.maven.repository.internal.DefaultArtifactDescriptorReader.loadPom (DefaultArtifactDescriptorReader.java:240) to check if maybe maven itself misses something here we need to also fill in the above method.

Jul 07 '22 06:07 laeubi

I finally got some time to revisit this pull request, and I think your suspicion was spot-on, @laeubi

To quickly explain what's going on: Tycho creates a bare-bones object for all Maven repositories which have been specified in the target platform definition, containing only the corresponding id and url. So it lacks the user credentials, mirrors,... Effectively anything contributed via the settings.xml.

Because those repositories are injected back into the Maven model, due to Issue #697, it then caused the seemingly unrelated stacktrace which had me stuck for quite a while.

Meaning I "only" had to inject settings.xml into those repositories, whenever they are created.

Thank you a lot for your help :)

java.lang.SecurityException: class "org.eclipse.core.runtime.Plugin"'s signer information does not match signer information of other classes in the same package

The error seems more like an Eclipse issue and unrelated to my changes.

Failed to bind to 0.0.0.0/0.0.0.0:58444

And this warning only happens on Windows... Likely a problem when setting up the mock HTTP server, would be my guess. Though I don't see why this fails for the m2 test but not the p2 test. :-|

Sep 14 '22 12:09 ghost

Github action failures are unrelated.

@pzi-dsa thanks for the fix and for the test-case! Lets see if this improves the situation for you :+1:
