Karaf maven plugin fails to read from GCP Artifact registry

[slm]

The Karaf maven plugin doesn't doesn't recognize the "artifactregistry" protocol preventing any Karaf-based projects from using GCP Artifact Registry.

Details are here:  https://issues.apache.org/jira/browse/KARAF-7516

[comaro]

The Apache issue claims it is following the Configure Maven documentation, but it shows a different version.

Please try using version 2.2.0 as shown in the Google Cloud documentation, as follows:

<build>
<extensions>
<extension>
<groupId>com.google.cloud.artifactregistry</groupId>
<artifactId>artifactregistry-maven-wagon</artifactId>
<version>2.2.0</version>
</extension>
</extensions>
</build>

I tried 2.2.0, but I'm still seeing the same failure.

Here is my extension setting:


com.google.cloud.artifactregistry
artifactregistry-maven-wagon
2.2.0

Hi, slm,

To work around this problem, we have found 2 possible solutions:
- Grant the Role "Artifact Registry Reader" to the Service Account related to the Karaf Maven plug-in.
- Use a dedicated Service Account to read from the Artifact Registry and add the credentials in the Artifact Registry URL.

Please tell me if it solved your issue, I will be waiting for your response.

Your suggestion did not have an effect unfortunately.

My account already had the Artifact Registry Repository Administrator
role. I added the Artifact Registry Reader role as suggested.

I'm still getting:

*java.net.MalformedURLException*: *unknown protocol: artifactregistry*

[comaro]

Is the account with the Artifact Registry Repository Administrator
role, the same for the plug in?

[slm]

Yes it is

Hi, slm,

Could you try changing the URL of your repository?

This documentation shows a sample:
`artifactregistry://region-maven.pkg.dev/PROJECTID/REPOID`

The URLs shown in here don’t seem to have a PROJECTID (or something like REDACTED_PROJECTID).

I am guessing java-repo is the REPOID, not the PROJECTID.
`artifactregistry://us-central1-maven.pkg.dev/java-repo/snapshots`

[slm]

The URL we are using was obtained from the gcloud command found in Artifact Registry -> selecting my registry -> Setup Instructions.  Found therein is a "gcloud artifacts print-settings mvn ..." command that displays the URL to be used.  I believe it is correct with the projectid first, then the repoid.

I think someone on your team needs to debug the artifactregistry-maven-wagon extension to get to the bottom of this issue.

Hi, slm,

For further research, your project would need to be inspected by support.

This can be done over a support case.

If not, I suggest you create a Public Issue Tracker.
