After migrating to Tycho 4.0.0-SNAPSHOT from Tycho 2.7.5, we now get the following warnings in our build:

[WARNING] Parameter 'qualifier' (user property 'buildQualifier') is read-only, must not be used in configuration

It occurs several times in the build of our product:

I can't find any qualifier in our repo that relates to this (only in bundle/feature versions, etc). I can't find any buildQualifier in our repo at all. We do make use of forceContextQualifier for the tycho-packaging-plugin (not sure if that is related or not).

Do you have any idea what is causing this warning?

From the error message you are using qualifier as a configuration parameter somewhere, maybe you can search for <qualifier> in pom.xml files as a first step?

<qualifier> doesn't occur anywhere in the repo, not in pom.xml files, nor in other files.

laeubi Jun 17, 2023

Do the build maybe passes buildQualifier as a maven option somewhere?

dhendriks Jun 17, 2023

Our build is defined in a Jenkinsfile, part of the same repo. Since I didn't find buildQualifier anywhere in the repo, it is also not in the Jenkinsfile, and thus not passed in the build.

Thats really strange, do you think you can reduce the problem to a small example project or provide an integration-test to demonstrate the issue?

Appears to derive (at least for me) from the use of 'qualifier' as part of the Bundle-Version entry in a plugin's MANIFEST.MF file.

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Automatic-Module-Name: net.certiv.tools.plugin
Bundle-SymbolicName: net.certiv.tools.plugin;singleton:=true
Bundle-Version: 1.2.1.qualifier
Bundle-Activator: net.certiv.certivtools.CertivTools
...

Why do you think so? the manifest has actually nothing to do with the pom.xml

grosenberg Jun 21, 2023

This is the only place in the entire project -- code and configuration -- that the word qualifier appears
Removing .qualifier results in a Tycho reported error:

[ERROR] Failed to execute goal org.eclipse.tycho:tycho-packaging-plugin:3.0.4:validate-version (default-validate-version)
on project net.certiv.tools.plugin; OSGi version 1.3.0 must have .qualifier qualifier for SNAPSHOT builds

Certainly appears that the Manifest is being evaluated by Tycho. Not certain that this is the actual source of the problem, but thought that it might be a clue.

We always get this warning in Tycho 3.0.5 too in our RCP Product build - https://github.com/archimatetool/archi

We also only use qualifier in our MANIFST.MF files same as OP.

Only occurs when building a product or site.

Locally I just upgraded Maven from 3.6.3 to 3.9.2 and I also started to receive these warnings:

[WARNING] Plugin issue(s):
[WARNING] * Plugin depends on the deprecated Maven 2.x compatibility layer, which may not be supported in Maven 4.x
[WARNING] Mojo issue(s):
[WARNING] * Mojo tycho-p2-repository:assemble-repository (org.eclipse.tycho.plugins.p2.repository.AssembleRepositoryMojo)
[WARNING] - Parameter 'qualifier' (user property 'buildQualifier') is read-only, must not be used in configuration

[WARNING] - Parameter 'qualifier' (user property 'buildQualifier') is read-only, must not be used in configuration

When I go back to Maven 3.6.3 they disappear.

Could it be that newer Maven versions define some properties in terms of other properties? Or that they have additional validation/checking or so?

We see this message in our Eclipse Memory Analyzer builds with Tycho 2.7.5. E.g.

I think this is more a "maven feature" so the used maven version influence if the warning is shown or not.

Yes see https://maven.apache.org/docs/3.9.2/release-notes.html

See also #2644. Basically p2-publisher injects a value into the maven model, and later maven validation complains, because read-only configuration arguments should not have a value.

So, how to proceed? Can something be done on the Tycho side? Should we report this to Maven? Or what?
