What changes were proposed in this pull request?

CI build is trying to download non-Apache artifacts from repository.apache.org:

[INFO] Downloading from apache-public-repository-group: https://repository.apache.org/content/groups/public/org/codehaus/groovy/groovy-all/2.5.19/groovy-all-2.5.19.pom
[INFO] Downloading from jenkins-releases: https://repo.jenkins-ci.org/releases/org/codehaus/groovy/groovy-all/2.5.19/groovy-all-2.5.19.pom
[INFO] Downloading from repo.jenkins-ci.org: https://repo.jenkins-ci.org/public/org/codehaus/groovy/groovy-all/2.5.19/groovy-all-2.5.19.pom
[INFO] Downloaded from repo.jenkins-ci.org: https://repo.jenkins-ci.org/public/org/codehaus/groovy/groovy-all/2.5.19/groovy-all-2.5.19.pom (25 kB at 309 kB/s)

Repositories defined in pom.xml have higher precedence than central repo inherited from super POM.

See https://infra.apache.org/infra-ban.html ("Excessive 404") for why this is a problem.

This change explicitly adds central as first repository.

@jomarko @porcelli @tkobayas could you please help review this?

[porcelli]

@jstastny-cz i think you are the one that has best knowledge about overall CI setup; could you help taking a look?

[jomarko]

I can confirm this resource doesn't exist:

• https://repository.apache.org/content/groups/public/org/codehaus/groovy/groovy-all/2.5.19/groovy-all-2.5.19.pom

while this one exists:

• https://repo.maven.apache.org/maven2/org/codehaus/groovy/groovy-all/2.5.19/groovy-all-2.5.19.pom

however, I am not expert in CI pipelines we have. If the opened PRs are green, we are probably fine. ideally, could you point to line in log where downloading is corrected by your PR?

Do you mean the following one from PR run?

[INFO] Downloading from central: https://repo.maven.apache.org/maven2/org/codehaus/groovy/groovy-all/2.5.19/groovy-all-2.5.19.pom
[INFO] Downloaded from central: https://repo.maven.apache.org/maven2/org/codehaus/groovy/groovy-all/2.5.19/groovy-all-2.5.19.pom (25 kB at 3.2 MB/s)
