Description

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.

Steps to reproduce

1. Resolve the pom in attached tar ball

$ 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

2. Verify some jars and poms are missing

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

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

3. maven test requires more files to be downloaded

bash-5.1# mvn test                                                                                                                                                           [0/1962]

4. Verify the missing files are downloaded

bash-5.1# ls ~/.m2/repository/org/apache/maven/maven-profile/2.0.6/
_remote.repositories          maven-profile-2.0.6.jar       maven-profile-2.0.6.jar.sha1  maven-profile-2.0.6.pom       maven-profile-2.0.6.pom.sha1
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  maven-core-2.0.6.pom       maven-core-2.0.6.pom.sha1
