------------------------------------
Summary: IVY retrieves jar's for parent POMs
Key: IVY-1564
URL: https://issues.apache.org/jira/browse/IVY-1564
Project: Ivy
Issue Type: Bug
Components: Maven Compatibility
Affects Versions: 2.4.0
Reporter: Daniel Cranford
The fix for IVY-920 introduced a behavior where IVY will try to retrieve the
jar corresponding to all POM packaged artifacts. The vast majority of pom
packaged artifacts are parent POMs which have have no jars. This means IVY is
wasting time trying to retrieve jars which don't exist.
Neither Maven nor Gradle have this problem. They are able to distinguish
between a pom referenced as a parent (for which no jar should be retrieved)
should and a pom packaged artifact referenced as a dependency (for which a jar
should be retrieved).
In our environment, failed lookup are particularly expensive due to timeouts,
leading to initial builds which take hours.
