Maven-publish and snapshot metadata

Help/Discuss
1

I have an odd issue with consuming published snapshot artifacts from one project, in another project.

In the consuming project i have configured a snapshot repo as follows:

allprojects {
    repositories {
        maven {
            url mavenRepoUrl
            mavenContent {
                releasesOnly()
            }
        }
        maven {
            url mavenSnapshotRepoUrl
            mavenContent {
                snapshotsOnly()
            }
        }
    }
}

And specific dependency in a sub-module:

dependencies {
    implementation(group: 'myproj.common', name: 'common-api', version: '3.5.12-SNAPSHOT') { transitive = false }
}

Running compileJava on this yields:

Execution failed for task ':proj2:submod:compileJava'.
> Could not resolve all files for configuration ':proj2:submod:compileClasspath'.
   > Could not find myproj.common:common-api:3.5.12-SNAPSHOT.
     Searched in the following locations:
       - https://myrepo.local/snapshots/myproj/common/common-api/3.5.12-SNAPSHOT/maven-metadata.xml
       - https://myrepo.local/snapshots/myproj/common/common-api/3.5.12-SNAPSHOT/common-api-3.5.12-SNAPSHOT.pom

the maven-metadata.xml should be found (curling the url returns as seen in the following traces)

Here’s a trace from the published project tasks:

> Task :common:common-api:publishMavenPublicationToMavenRepository

  Build cache is disabled
Task ':common:common-api:publishMavenPublicationToMavenRepository' is not up-to-date because:

:common:common-api:publishMavenPublicationToMavenRepository (Thread[Execution worker for ':',5,main]) completed. Took 5.898 secs.
:common:common-api:publishAllPublicationsToMavenRepository (Thread[Execution worker for ':',5,main]) started.

I see the maven-metadata.xml uploaded is to the artifact folder, not the versioned folder.

The metadata file for the xml looks like this in the local build:

$ cat common/common-api/build/tmp/publishMavenPublicationToMavenRepository/snapshot-maven-metadata.xml 
<?xml version="1.0" encoding="UTF-8"?>
<metadata modelVersion="1.1.0">
  <groupId>myproj.common</groupId>
  <artifactId>common-api</artifactId>
  <version>3.5.12-SNAPSHOT</version>
  <versioning>
    <snapshot>
      <timestamp>20200622.172315</timestamp>
      <buildNumber>2</buildNumber>
    </snapshot>
    <lastUpdated>20200622172315</lastUpdated>
    <snapshotVersions>
      <snapshotVersion>
        <extension>jar</extension>
        <value>3.5.12-20200622.172315-2</value>
        <updated>20200622172315</updated>
      </snapshotVersion>
      <snapshotVersion>
        <extension>pom</extension>
        <value>3.5.12-20200622.172315-2</value>
        <updated>20200622172315</updated>
      </snapshotVersion>
      <snapshotVersion>
        <extension>module</extension>
        <value>3.5.12-20200622.172315-2</value>
        <updated>20200622172315</updated>
      </snapshotVersion>
    </snapshotVersions>
  </versioning>
</metadata>

But curling that from the repo shows different content (and the task output from the publish didn’t show this file being uploaded anyways):

$ curl https://myrepo.local/snapshots/myproj/common/common-api/3.5.12-SNAPSHOT/maven-metadata.xml
<?xml version="1.0" encoding="UTF-8"?>
<metadata modelVersion="1.1.0">
  <groupId>myproj.common</groupId>
  <artifactId>common-api</artifactId>
  <version>3.5.12-SNAPSHOT</version>
  <versioning>
    <snapshot>
      <buildNumber>1</buildNumber>
    </snapshot>
    <lastUpdated>20200622172321</lastUpdated>
  </versioning>
</metadata>

Here’s the associated publish gradle config

$ cat gradle/publish.gradle
apply plugin: 'maven-publish'

publishing {
    publications {
       maven(MavenPublication) {
            from components.java
        }
    }
    repositories {
        maven {
            credentials {
                username "${artifactory_username}"
                password "${artifactory_apikey}"
            }
            if (project.version.endsWith("-SNAPSHOT")) {
                url "https://myrepo.local/snapshots/"
            } else {
                url "https://myrepo.local/prod/"
            }
        }
    }
}

Am i doing anything noticeably wrong here?
