[IVY-1511] Ivy fails to resolve maven dependencies that were build with the maven-javadoc-plugin and option "maven.javadoc.skip"

• Type: Bug
• Status: Closed
• Priority: Major
• Resolution: Cannot Reproduce
• Affects Version/s: 2.4.0
• Component/s: Maven Compatibility

Environment

Ant + Ivy, Windows, Java 1.6.0 32 Bit, Maven2-Repository (Artifactory)

Description

Given:
************

• An ivy module that depends on a module built with Maven.
• The Maven module was built using the maven-javadoc-plugin (inherited from its parent) but with "maven.javadoc.skip" set to "true", thus generating no -javadoc artifact.
• In general, the resolution of maven artifacts works flawlessly using the ibiblio resolver (m2compatible=true)

Problem:
************

• Resolution fails because ivy assumes that the -javadoc artifact is present which is not the case

Workaround:
************

• Exclude artifacts with -javadoc classifier

Suggestions:
************

• Include publications for maven artifacts with classifier javadoc (sources...) only if those files are actually present on the repository, or

Examples:
***********
