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

There are two setting.xml in windows.

• %MAVEN_HOME%\conf\
• %userprofile%\.m2\

If %userprofile%\.m2\setting.xml takes effect, maven will not access %MAVEN_HOME%\conf\setting.xml.

Answer 2

As stated in @John's answer, the fact that there is already a 0.1.2-SNAPSHOT, interfered with my new non-SNAPSHOT version 0.1.2. Since the 401 Unauthorized error is nebulous and unhelpful--and is normally associated to user/pass problems--it's no surprise that I was unable to figure this out on my own.

Changing the version to 0.1.3 brings me back to my original error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-install-plugin:2.4:install (default-install) on project xbnjava: Failed to install artifact com.github.aliteralmind:xbnjava:jar:0.1.3: R:\jeffy\programming\build\xbnjava-0.1.3\download\xbnjava-0.1.3-all.jar (The system cannot find the path specified) -> [Help 1].

A sonatype support person also recommended that I remove the <parent> block from my POM (it's only there because it's in the one from ez-vcard, which is what I started with) and replace my <distributionManagement> block with

<distributionManagement>
  <snapshotRepository>
    <id>ossrh</id>
    <url>https://oss.sonatype.org/content/repositories/snapshots</url>
  </snapshotRepository>
  <repository>
    <id>ossrh</id>
    <url>https://oss.sonatype.org/service/local/staging/deploy/maven2/</url>
  </repository>
</distributionManagement>
and then make sure that lines up with what's in your settings.xml:
<settings>
  <servers>
    <server>
      <id>ossrh</id>
      <username>your-jira-id</username>
      <password>your-jira-pwd</password>
    </server>
  </servers>
</settings>

After doing this, running mvn deploy actually uploaded one of my jars for the very first time!!!

That's one big Maven problem out of the way. Only 627 more to go.

Some users may have entered the email address instead of the user name by mistake. This may happen unconsciously when the name in the email address is the same as the user name.
