Fails to resolve plugin dependencies in Maven 3.0.x
---------------------------------------------------
Key: MNG-5060
URL: http://jira.codehaus.org/browse/MNG-5060
Project: Maven 2 & 3
Issue Type: Bug
Reporter: John Smart
Priority: Blocker
For some projects, Maven 3.x fails to resolve/download plugin dependencies,
whereas Maven 2.x worked fine. Could be an aether bug. The artifact when
resolving in aether has "remoteRepositories" : size:0
The situation appears to be that it it downloads it from central, adds in
_maven.repositories as
#NOTE: This is an internal implementation file, its format can be changed
without prior notice.

easyb-core-1.1.jar>central=
easyb-core-1.1.pom>central=
and then proceeds to only look for
easyb-core-1-1.pom>=
(i.e. local only repository) which isn't there.
An example of this problem can be reproduced by building the following project
from github: https://github.com/wakaleo/thucydides/tree/maven-3.0.x-bug-example
Just run mvn install. With Maven 2.2.1 it works fine. With Maven 3.0.x you get
the following:

It does this despite the fact that the dependency in question is (a) on
central, (b) in the local repository, or (c) both. If you try to install it
manually, it fails with a message saying that there is already a JAR file there.
