Wei Lin created MNG-7394:
----------------------------

             Summary: dependency:go-offline does not download all dependencies
                 Key: MNG-7394
                 URL: https://issues.apache.org/jira/browse/MNG-7394
             Project: Maven
          Issue Type: Bug
          Components: Plugins and Lifecycle
    Affects Versions: 3.8.4
            Reporter: Wei Lin
         Attachments: demo.tar.gz

It appears the go-offline goal of the maven dependency plugin downloads only jar but no pom for some of the dependencies, and only pom but no jar for some other dependencies.

h2. Steps to reproduce

h3. 1. Resolve the pom in attached tar ball

{code}
$ docker run -it --rm -v $(greadlink -f demo):/tmp/demo:ro maven:3.8.4-eclipse-temurin-11-alpine bash
bash-5.1# mvn -B -f /tmp/demo/pom.xml dependency:go-offline
{code}

h3. 2. Verify some jars and poms are missing

{code:title=there is no pom.xml for maven-core 2.0.6}
bash-5.1# ls ~/.m2/repository/org/apache/maven/maven-core/2.0.6/
_remote.repositories       maven-core-2.0.6.jar       maven-core-2.0.6.jar.sha1
{code}

{code:title=there is no jar for maven-profile 2.0.6}
bash-5.1# ls ~/.m2/repository/org/apache/maven/maven-profile/2.0.6/
_remote.repositories          maven-profile-2.0.6.pom       maven-profile-2.0.6.pom.sha1
{code}

h3. 3. maven test requires more files to be downloaded

{code}
bash-5.1# mvn test                                                                                                                                                           [0/1962]
