Anthony Dahanne created MDEP-356:
------------------------------------
Summary: maven dependency plugin should use maven 3 dependency
resolver, aether
Key: MDEP-356
URL: https://jira.codehaus.org/browse/MDEP-356
Project: Maven 2.x Dependency Plugin
Issue Type: Bug
Components: purge-local-repository
Affects Versions: 2.4, 2.5
Environment: mac os x or linux, maven 3.0.4 (maven 3.0.3 does not have
the same behaviour, it fails at removing the local artifacts)
Reporter: Anthony Dahanne
Attachments: pom.xml
problem initially described on the maven users mailing list :
http://mail-archives.apache.org/mod_mbox/maven-users/201206.mbox/browser
Given the attached pom, and using maven 3.0.4 (important, it does not work
with 3.0.3, it fails at removing the local artifacts)
# do a mvn clean install
# then do a mvn
org.apache.maven.plugins:maven-dependency-plugin:2.4:purge-local-repository
-Dverbose=true -DresolutionFuzziness=version
it will work as designed, removing javax.servlet:servlet-api:jar:2.5 and
net.dahanne.gallery:commons-gallery:jar:2.1.0-SNAPSHOT from your local repo,
before re downloading them.
but, the following message is displayed :
{noformat}
[WARNING] Missing POM for javax.servlet:servlet-api:jar:2.5
[WARNING] Missing POM for net.dahanne.gallery:commons-gallery:jar:2.1.0-SNAPSHOT
{noformat}
It actually means the plugin could not "see" those artifacts in my local repo;
it may be related to the fact that dependency plugin does not use aether to
resolve the tree.
Other problems should arise, as mentioned by Stephen Connolly on the mailing
list :
"When I last chatted on this with Benjamin, he left me with the distinct
impression that I should not rely on the output of dependency:tree when run on
m3 until it has been adapted to query aether's graph more directly"
The dependency plugin should use the same dependency resolver as maven 3, ie
aether.
