java.io.IOException: Error writing to server

    "Allow Anonymous Access" general setting causes maven to NOT send user credentials when uploading artifacts. This is a problem because we would like to allow anonymous users read access to our repo but only allow authenticated users to upload artifacts. Everything works fine if I remove anonymous access to just our single repo, but this is not a feasible solution in our environment. settings.xml: <server> <id>repo-release</id> <username>...</username> <password>...</password> <configuration> <timeout>600000</timeout> <!-- milliseconds --> </configuration> </server> <server> <id>repo-snapshot</id> <username>...</username> <password>...</password> <configuration> <timeout>600000</timeout> <!-- milliseconds --> </configuration> </server> Error message: Using Wagon implementation lightweight from default mapping for protocol https [DEBUG] Checking for pre-existing User-Agent configuration.
