Sometime SNAPSHOTs can not be downloaded in an an online build
--------------------------------------------------------------
Key: MNG-2941
URL: http://jira.codehaus.org/browse/MNG-2941
Project: Maven 2
Issue Type: Bug
Affects Versions: 2.0.5
Environment: All
Reporter: Anita Kulshreshtha
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.
