Description

When an offline build fails because a SNPSHOT was not available locally, the SNAPSHOT can not be downloaded during a subsequent online build. During the offline build a file maven-metadata-apache-snpshots.xml (with the following contents in this example) is created in .m2 repo:
<?xml version="1.0" encoding="UTF-8"?><metadata>
<groupId>org.apache.geronimo.genesis</groupId>
<artifactId>genesis</artifactId>
<version>1.2-SNAPSHOT</version>
</metadata>
All subsequent online builds fail to download this artifact from the repository with error message given below. After deleting the metadata file corresponding to the repository in which this artifact is available (maven-metadata-apache-snpshots.xml file in this example) , the artifact can be downloaded successfully.

This trace can be produced by any SNAPSHOT in any project, the following steps are for geronimo:
1. Delete the above SNAPSHOT from the local repo.
2. Build geronimo offlne, the build will fail.
3. Build online, the following message will be generated.
4. Delete the above metadata file, and build online, the SNAPSHOT will get downloaded successfully.

The default update policy is 'daily', so I think the behavior is as described.

http://maven.apache.org/ref/2.0.4/maven-model/maven.html#class_pluginRepository

You can change the update policy to 'always' or 'interval:###' for the snapshot repos, or use -U on the command line to force updates.

It will be nice if maven could distinguish between a non-existent SNAPSHOT and an 'updated' SNAPSHOT. In a project like geronimo being able to
download a single new SNAPSHOT without updating all the other existing SNAPSHOTs is very useful.

Perhaps this problem is related to MNG-4142.
The build tries to download : http://people.apache.org/repo/m2-snapshot-repository/org/apache/geronimo/genesis/genesis/1.2-SNAPSHOT/genesis-1.2-SNAPSHOT.pom
It shouldn't because it have to read metadata from the remote repo to download the timestamped version and not the -SNAPSHOT.
