Hi all,
I'm looking for some help to solve an issue related apparently with m2e plugin in Eclipse.
I need to access to some artifacts located in a remote repository that needs authentication. After configure the settings.xml as explained in the Maven docs the command "mvn compile" works just fine and the artifacts are downloaded to local repository. But when using Eclipse to do the same a "Could not transfer artifact [...] Error code 401, Unauthorized" error is thrown and the jars are obviously not downloaded.
I have tried with different versions of Eclipse (Luna and Mars) and with updated version of the m2e plugin but the result is always the same.

Has anyone experienced a similar issue?

I have found some related posts where people seems to have similar issues but the few solutions proposed don't work for me.

Regards

Hi Pablo,
Are you behind any proxy or firewall? In case then change your eclipse proxy settings.

Finally seems that the problem was related to the credentials of the user. The remote repository was an Artifactory repository and using the password encryption of the Artifactory web (in the user profile section) instead of the Maven encryption solved the problem.
