Why am I getting a “401 Unauthorized” error in Maven?

Question

Why am I getting a \"401 Unauthorized\" error in Maven?

Here\'s the error I\'m getting when calling mvn deploy (full logs at the bottom):

Answer 1

just change in settings.xml these as aliteralmind says:

  <server>
      <id>nexus-snapshots</id>
      <username>MY_SONATYPE_DOT_COM_USERNAME</username>
      <password>MY_SONATYPE_DOT_COM_PASSWORD</password>    
 </server>

you probably need to get the username / password from sonatype dot com.

Answer 2

In Nexus version 3.13.0-01, the id in the POM's distributionManagement/repository section MUST match the servers/server/id and mirrors/mirror/id in your maven settings.xml. I just replaced nexus v3.10.4 (with 3.13.0-01) and it wasn't needed to match for 3.10.4.

Answer 3

It could be caused by wrong version, you can double check the parent's version and lib's version, to make sure they're correct and not duplicated, I've experienced same problem

Answer 4

Had similar issue. Had to pin the maven deploy plugin to specific version in pom.xml:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-deploy-plugin</artifactId>
     <version>2.8.2</version>
</plugin>

This version is what broke my builds:

[INFO] --- maven-deploy-plugin:3.0.0-M1:deploy (default-cli) @ dbl ---

Answer 5

I've had similar errors when trying to deploy a Gradle artefact to a Nexus Sonatype repository. You will get a 401 Unauthorized error if you supply the wrong credentials (password etc). You also get an error (and off the top of my head is also a 401) if you try to publish something to a releases repository and that version already exists in the repository. So you might find that by publishing from the command line it works, but then when you do it from a script it fails (because it didn't exist in the repository the first time around). Either publish using a different version number, or delete the old artefact on the server and republish.

The SNAPSHOTS repository (as opposed to the releases repository) allows you to overwrite a similarly numbered version, but your version number should have "-SNAPSHOT" at the end of it.

Answer 6

I had put a not encrypted password in the settings.xml .

I tested the call with curl

curl -u username:password http://url/artifactory/libs-snapshot-local/com/myproject/api/1.0-SNAPSHOT/api-1.0-20160128.114425-1.jar --request PUT --data target/api-1.0-SNAPSHOT.jar 

and I got the error:

{
  "errors" : [ {
    "status" : 401,
    "message" : "Artifactory configured to accept only encrypted passwords but received a clear text password."
  } ]
}

I retrieved my encrypted password clicking on my artifactory profile and unlocking it.
