Thread-topic: [m2e-users] m2e fails to download artifacts - Error 401 Unauthorized

Thanks for the quick reply! I just found a solution to the problem:

I was using http:// urls to access the repository. The proxy before the repo does http-to-https redirection (302 Moved, I think). After switching to https:// in settings.xml, downloading artefacts from m2e works again.

It's a bit strange that the same config worked with Eclipse Luna, however.

Mit freundlichem Gruß / Best regards

Betreff: Re: [m2e-users] m2e fails to download artifacts - Error 401 Unauthorized

I am not aware of any problems with http auth in m2e 1.6, so this must be new bug/limitation. To help you troubleshoot this further, I will need tcp dump or similar of a failed authentication attempt (make sure you don't reveal passwords or any sensitive info!). m2e uses aether-connector-okhttp [1] for http/https support, so you can debug this yourself if you prefer.

Hi,

since upgrading to Eclipse Mars, m2e fails to download any artifact from our internal Artifactory. The download works fine when building with Maven 3.3.3 from the command line, so I assume my settings.xml is correct.

I always get "Error code 401, Unauthorized"

In Eclipse Luna, everything worked as expected. I'm using a fresh workspace for Eclipse Mars, so maybe there's something I have to configure in Eclipse to get it to work again?

Here's a stacktrace from Eclipse's .log with the exception:
