--------------------------------
Summary: Shade Plugin gets stuck in infinite loop building
dependency reduced POM
Key: MSHADE-148
URL: https://jira.codehaus.org/browse/MSHADE-148
Project: Maven 2.x Shade Plugin
Issue Type: Bug
Affects Versions: 2.1
Environment: OS X 10.7.5
Reporter: Rob Vesse
Attachments: pom.xml, shade-bug.txt
I have encountered a bug whereby the shade plugin gets stuck in an infinite
loop in the step of creating a dependency reduced POM.
I have attached a minimal POM that reproduces the issue and done some debugging
on this. The problem seems to be caused by using both the jar and test-jar
version of a dependency (jena-fuseki in my example) while also including a jar
dependency that is a transitive dependency of the other dependencies (jena-arq
in my example). Removing either the jar/test-jar resolves the problem and so
does removing the other jar dependency.
The problem appears to be that the plugin is getting stuck endlessly trying to
produce the dependency-reduced-pom.xml
If I watch the file over time it is repeatedly deleted and rewritten, each time
it is written it gets larger. When I manage to kill the process at a point
where the file is non-empty I can see that the plugin is endlessly adding the
same set of <exclusions> to one of the jena-fuseki dependencies.
