Maven Bintray distribution in Eclipse is not uploading jar files. Error code 401 (Unauthorized) but only for jar packaging?

I'm trying to deploy a project to Maven to bintray which is successfully uploads the pom file but returns an Error code 401 when uploading jar files.

I have gone through the bintray tutorial, set my settings.xml up properly, added the correct distributionManagement etc fields to my pom file, made sure the project is not a snapshot etc. but cannot seem to get the uploading of jar files working? I've been trying to figure out what might be going on but with no success.

Details on the stack trace pom.xml, settings.xml and eclipse configuration are below. The entire project can be found on github

Am I missing something obvious here? Any help much appreciated.

The configuration I am using in eclipse to deploy the project.

Update: Solution

The solution to this problem is to install maven externally and use that installation instead of the embedded version that comes with Eclipse. This completely solves the problem. Go to preferences->Maven->Installation to add a new Maven installation then make sure that version is selected in the run configuration.

Try to use an external Maven installation. I think maven embedded in eclipse (3.6.3 version of Maven) has an issue with big files (pom.xml is deployed correctly).

We tried with maven 3.5.1, 3.6.1 and 3.6.3 external installation and deploys correctly, but give us a 401 error with big files (jar or war) with embedded one (3.6.3). Same config and user.

There is a bug reported, related with this: https://bugs.eclipse.org/bugs/show_bug.cgi?id=566513

And more StackOverflow problems reported: https://stackoverflow.com/questions/61536737/eclipse-maven-deploy-war-to-nexus-oss-access-denied-error-code-401-unauthorized

Edit: Some news about the bug reported. It seems to be related with okhttp component added to eclipse, and this library has this bug:

https://github.com/takari/aether-connector-okhttp/issues/29

These 2 workarounds are proposed until the bug will be fixed:

• Use an external Maven runtime in the Launch Configuration instead of embedded one (so aether is not included)
• Set -Daether.connector.basic.threads=1 in the launch configuration.

(you can see that in: https://bugs.eclipse.org/bugs/show_bug.cgi?id=562847#c7)

Regards,

The error indicates an access issue based upon the HTTP 401 code message:

Error code 401, Unauthorized

Double check your username and password is correct.

Better yet do not put your password into plaintext and instead use a password hash.
