How to rebuild maven-metadata.xml in Artifactory?

Question

We're using Artifactory 3.9.2 and had to merge parts of two repositories (by copying over the artifacts) which had the same (SNAPSHOT-versioned) artifact. This screwed up the maven-metadata.xml. In Nexus its possible to simply rebuild the metadata for this artifact and let the repository manager sort out things for you. I can't seem to find any links/explanations on how to do this with Artifactory. Could somebody please tell me how I can do this?

Answer 1

I'm not sure if this is possible in the UI, but you can do it using the REST API. Try posting a request using curl:

curl -v -X POST http://artifactory/artifactory/api/maven/calculateMetadata/my-repository/com/foo/bar

They decided to call it "calculate metadata" instead of "rebuild metadata" which is not very suitable IMHO.

Answer 2

We are using artifactory 4.4.2 and I came here since the maven-metadata.xml files were missing from folders in our artifactory where we had deployed war files manually using the REST API.

The important thing to note is that calculateMetadata will not do anything if there are no pom.xml files in place! (source)

Therefore, after we deployed com/company/project/art/1.0/art-1.0.war, we needed to make a "blank" art-1.0.pom and deploy it to the correct place.

Here's an example of a blank pom.

<?xml version="1.0" encoding="UTF-8"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
    http://maven.apache.org/xsd/maven-4.0.0.xsd" 
    xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.company.project</groupId>
  <artifactId>art</artifactId>
  <version>1.0</version>
  <description>POM was created from a script</description>
</project>

Now, the second thing we notice - once you deploy art-1.0.pom the maven metadata is calculcated automatically (at least, for a local repo with default maven2 layout).

Therefore we didnt need to call calculateMetadata via REST api at all - it seems to be automatic whenever you upload a pom.
