> We're using Artifactory on the server side, and ivy / sbt to publish
> artifacts upstream.
> After publishing several -SNAPSHOT versions of a project, trying to use it
> from Maven, resulted in a warning and ultimately a build failure because it
> cannot determine the dependencies:
> {code}[WARNING] The POM for com.foo:bar:jar:0.4.0-20130404.093655-3 is
> missing, no dependency information available{code}
> This is the corresponding maven-metadata-snapshots.xml:
> {code:xml}
> <metadata>
> <groupId>com.foo</groupId>
> <artifactId>bar</artifactId>
> <version>0.4.0-SNAPSHOT</version>
> <versioning>
> <snapshot>
> <timestamp>20130404.090532</timestamp>
> <buildNumber>2</buildNumber>
> </snapshot>
> <lastUpdated>20130404093657</lastUpdated>
> <snapshotVersions>
> <snapshotVersion>
> <extension>pom</extension>
> <value>0.4.0-20130404.090532-2</value>
> <updated>20130404090532</updated>
> </snapshotVersion>
> <snapshotVersion>
> <extension>jar</extension>
> <value>0.4.0-20130404.093655-3</value>
> <updated>20130404093655</updated>
> </snapshotVersion>
> </snapshotVersions>
> </versioning>
> </metadata>
> {code}
> As you can see, the <value> for the jar artifact and the pom artifact differ:
> 0.4.0-20130404.093655-3
> 0.4.0-20130404.090532-2
> Apparently, artifactory optimizes the case when an artifact doesn't change;
> it does not create a new file, but just links to the existing one.
> Maven, however, takes a shortcut and makes the erroneous assumption that the
> values for pom and jar artifact always match up.
> The attached patch fixes this.
