Description

I see this problem when building nexus-proxy. This is due to maven-jar-plugin

Caused by: org.apache.maven.project.DuplicateArtifactAttachmentException: Duplicate artifact attachment detected. (project: org.sonatype.nexus:nexus-proxy:jar:1.3.0-SNAPSHOT; illegal attachment: org.sonatype.nexus:nexus-proxy:jar:tests:1.3.0-SNAPSHOT)

Seems to be ignoring the classifier during the comparison (illegal attachment is the tests jar)

Identical plugin executions are allowed in pom. This can cause failure in Maven 3 (since there is no longer cloning of maven project) on duplicate attached artifacts. Maven just logs warning, no longer throws exception.
