Michael Osipov commented on MSITE-663:
--------------------------------------
In general, omitting the relative path and not being present local, Maven
should try to download from remote. Did you try that?
> Build fails with message "Unable to read local module-POM"

> parent-pom is successfully deployed to NEXUS repository before the execution
> of {{mvn clean site}} with following command:
> {{mvn deploy
> -DaltDeploymentRepository=snapshots::default::http://MyServer:8081/nexus/content/repositories/snapshots}}
> And finally the problem itself:
> When I run {{mvn clean site}} right after the deployment of parent-pom site
> is built successfully. If I delete the folder (with its content) "my" (it
> contains the parent-pom) from the local repository (~/.m2/repository) and
> then try to build the site with {{mvn clean site}} I am getting the error
> described at the beginning. Actually Maven downloads the parent-pom from the
> NEXUS. I have compared the downloaded files and files which have been
> generated after the deployment and have realized that few are missing, for
> instance maven-metadata-local.xml near to "0.1-SNAPSHOT" folder.
> So when I am trying to run the site building job from Jenkins I am getting
> the error described above, because the parent-pom is not deployed from the
> machine where Jenkins run.
