Eclipse maven plugin getting HTTP 416 on flask fetch

I am getting this error in eclipse logs when I use maven integration plugin for eclipse in my project:

Build errors for transport-data; org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:2.4.3:resources (default-resources) on project transport-data: Execution default-resources of goal org.apache.maven.plugins:maven-resources-plugin:2.4.3:resources failed: Plugin org.apache.maven.plugins:maven-resources-plugin:2.4.3 or one of its dependencies could not be resolved: The following artifacts could not be resolved: org.codehaus.plexus:plexus-interactivity-api:jar:1.0-alpha-4, org.apache.maven.shared:maven-filtering:jar:1.0-beta-4, org.codehaus.plexus:plexus-interpolation:jar:1.13: Failure to transfer org.codehaus.plexus:plexus-interactivity-api:jar:1.0-alpha-4 from http://repo1.maven.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.codehaus.plexus:plexus-interactivity-api:jar:1.0-alpha-4 from/to central (http://repo1.maven.org/maven2): Failed to transfer http://repo1.maven.org/maven2/org/codehaus/plexus/plexus-interactivity-api/1.0-alpha-4/plexus-interactivity-api-1.0-alpha-4.jar. Error code 416, Requested Range Not Satisfiable

From the browser I can access the jar, but how is it that the plugin gets a 416 status response?

I am using STS 2.7.2.RELEASE (Eclipse 3.6) with Maven integration plugin on Maven 2.2.1 and my OS is Ubuntu 10.10. If someone could help me explain this mystery, I would be very grateful.

Thank!
