Deploying Maven project via GitHub actions fails - maven

Question

I'm trying to deploy a multi module project to GitHub packages but whenever Maven hits the "deploy" cycle it fails.
my GitHub action job:
release:
name: Release 🚀
# needs: test
runs-on: ubuntu-latest
permissions:
contents: write
actions: write
repository-projects: write
packages: write
steps:
- uses: actions/checkout#v3
with:
ref: master
- uses: actions/setup-java#v3
with:
java-version: 17
distribution: adopt
cache: maven
- name: Release package
run: |
git config user.name "githubaction[bot]"
git config user.email "actions#github.com"
mvn -B release:prepare
mvn -B release:perform
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
My pom files has the needed config:
<distributionManagement>
<!-- Github distribution -->
<repository>
<id>github</id>
<name>GitHub Packages</name>
<url>https://maven.pkg.github.com/MYUSERNAME/${project.artifactId}</url>
</repository>
</distributionManagement>
<scm>
<developerConnection>scm:git:https://github.com/MYUSERNAME/${project.artifactId}</developerConnection>
</scm>
The prepare step goes fine but a soon as Maven tries to perform the release (and thus hits the deploy stage) I get the error:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.8.2:deploy (default-deploy) on project my-artifact-sub-module: Failed to deploy artifacts: Could not find artifact my-artifact-sub-module:jar:1.1.0 in github (https://maven.pkg.github.com/mathiasbosman/fs-core) -> [Help 1]
Which is bizar as right before it fails Maven logs:
[INFO] Uploading to github: https://maven.pkg.github.com/my/path/my-artifact-sub-module/1.1.0/my-artifact-sub-module-1.1.0.jar
[INFO] Uploading to github: https://maven.pkg.github.com/my/path/my-artifact-sub-module/1.1.0/my-artifact-sub-module-1.1.0.pom
The structure would be:
my-artifact (pom)
- my-artifact-sub-module (jar)
- my-artifact-sub-module-two (jar)
I tried calling mvn deploy manually in a seperate step but it gives me the same result.

Answer 1

The scm url apperently was wrong (missing the .git extension)
As simple as that.
The complete scm:
<scm>
<connection>scm:git:${project.scm.url}</connection>
<developerConnection>scm:git:${project.scm.url}</developerConnection>
<url>https://github.com/MYUSERNAME/${project.artifactId}.git</url>
<tag>HEAD</tag>
</scm>
