Sonatype – 401 Content access is protected by token

Today I run into a maven problem during deployment of my snapshot releases to https://oss.sonatype.org. The upload was canceled with a message like this one:

[ERROR] Failed to execute goal org.sonatype.plugins:nexus-staging-maven-plugin:1.6.13:deploy (injected-nexus-deploy) on project imixs-workflow-index-solr: Failed to deploy artifacts: Could not transfer artifact org.imixs.workflow:imixs-workflow:pom:6.0.7-20240619.183701-1 from/to ossrh (https://oss.sonatype.org/content/repositories/snapshots): authentication failed for https://oss.sonatype.org/content/repositories/snapshots/org/imixs/workflow/imixs-workflow/6.0.7-SNAPSHOT/imixs-workflow-6.0.7-20240619.183701-1.pom, status: 401 Content access is protected by token -> [Help 1]

[ERROR]   mvn <args> -rf :imixs-workflow-index-solr

This may happen if you have overlooked the fact that Sonatype has introduced a new token-based authentication method.

Update your maven settings.xml file

What you need first, is to remove your hard coded userid/password from your maven settings.xml file (located in your home directory .m2/)

Your server config for ossrh should look like this:

<settings>
   <servers>
    <server>
     <id>ossrh</id>
     <username>token-username</username>
     <password>token-password</password>
    </server>
   </servers>
</settings>

For this you need to generate a token first. If you still use your plaintext userid/password this will no longer work. Find details here.

Login to https://oss.sonatype.org with your normal user account
Select under your login name the menu option “Profile”
Click on the ‘Profile’ tab
Generate a new access token

This will show you the token to be replaced with your old userid/password in your settings.xml file

That’s it. Now your deployment should work again.

Eclipse Maven Plugin – Could not handle artifact type Jar Module

When using Eclipse with the integrated Maven Plugin, I am for some time now around with the slightly annoying error message:

Eclipse Maven - Could not handle artifact type [JarModule]

This message appears whenever I update my maven project in eclipse with the command ‘Maven->Update Project’.

I figured out now, that the reason for this message is a JarModule configuration in the pom.xml file of my EAR project. The Eclipse Maven plugin is simply unable to handle such pom files.

The solution seems to be quite simple: Open the workspace preferences dialog and just disable the option “Maven -> Java EE Integration -> Enable Java EE configuration”.

It is also possible to disable this option not for the complete workspace but for the affected EAR project. In this case you can enable the Project Specific Settings, and disable the ‘Java EE configuration’.

So you can use the Maven Java EE Integration still for other modules (e.g. Web, JPA). I have tested this with the new Eclipse Neon release.

Building Websites with Markdown and Maven

If you want to setup a new web site, today there are a lot of frameworks and content management systems in the market. One of the most common is WordPress which can not only be used as a blog software but also to build pretty web pages. But WordPress has some disadvantages in my eyes. It is build with a lot of PHP code, you need a database and at least you will be attacked by masses of hackers. If you only plan to setup a small web site you can do this with pure HTML. But this isn’t an ideal solution if you want to separate content form design – which is a best practice in these days. Continue reading “Building Websites with Markdown and Maven”
