{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
