Migration to Maven 3.0.1 - Deploy fails with Error: 500 only for top most maven-metadata.xml

Question

I'm testing out migration to Maven 3.0.1 from 2.2.1.

All phases run fine except for the deploy phase.

When I first run with 2.2.1, everything runs fine.

Then I make the switch to 3.0.1 and run the same command and everything goes fine except for the top most maven-metadata.xml file. When maven tries to upload that file, I'm getting a http Error: 500.

If you notice in the log below:

This fails:

Uploading: http://mvn.***.com:8080/artifactory/***-project-assets/com/***/deployment/ThirdPartyDeploymentProject/0.0.1-SNAPSHOT/maven-metadata.xml

But this succeeds:

Uploading: http://mvn.***.com:8080/artifactory/***-project-assets/com/***/deployment/ThirdPartyDeploymentProject/maven-metadata.xml  

It surprises me that I'm not finding much information on this issue. Then again, maven 3 has been out only for about 8 months.

I found these two issues that I don't think are relevant to me: _http://maven.40175.n5.nabble.com/Created-MSITE-531-Site-deployment-fails-on-googlecode-repository-unnecessary-path-element-in-WebDAV--td3307584.html

_http://maven.40175.n5.nabble.com/Moved-WAGON-319-Site-deployment-fails-on-googlecode-repository-unnecessary-path-element-in-WebDAV-UR-td3308501.html

I have also tried removing the old artifacts entirely from the 'artifactory' and deploying again.

I hope someone could point me in the right direction here.

I'm pasting the relevant info below.

Thanks in advance.

Here's the relevant portion of the console output:

Answer 1

I found the solution.

I had posted the question here as well

As pointed out by Benjamin here the problem is that the new metadata format that maven 3 uses causes problems with the old version of 'artifactory' we're using as our repository manager.

The solution is to use this parameter: -Dmaven.metadata.legacy=true
