Maven fails with tomcat-maven-plugin since this morning

Question

Since this morning Maven can not build any project that requires tomcat-maven-plugin. I tried with the minimalistic pom.xml, with just that one dependency, but in all cases I get the following:

[INFO] Error building POM (may not be this project's POM).

Project ID: org.codehaus.mojo:tomcat-maven-plugin

Reason: Error getting POM for 'org.codehaus.mojo:tomcat-maven-plugin' from the repository: Unable to read local copy of metadata: Cannot read metadata from 'C:\Users\*\.m2\repository\org\codehaus\mojo\tomcat-maven-plugin\maven-metadata-codehaus releases.xml': end tag name must match start tag name

from line 7 (position: TEXT seen ...\n... @9:8)
org.codehaus.mojo:tomcat-maven-plugin:pom:LATEST

for project org.codehaus.mojo:tomcat-maven-plugin

First, I tried deleting the local data and redownloading, but I just got checksum failures. I opened maven-metadata-codehaus releases.xml just to see this inside:

301 Moved Permanently

Moved Permanently

The document has moved https://nexus.codehaus.org/content/repositories/releases/org/codehaus/mojo/tomcat-maven-plugin/maven-metadata.xml here.

I tired changing versions and repositories, but nothing helped. Any ideas anyone?

P.S. Here's the minimal pom I tried with:

<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd"&gt;
<modelVersion>4.0.0</modelVersion>

<groupId>org.codehaus.mojo</groupId>
<artifactId>my-project</artifactId>
<version>1.0</version>

<pluginRepositories>
<pluginRepository>
<id>Codehaus Snapshots</id>
<url>http://snapshots.repository.codehaus.org/&lt;/url&gt;
<snapshots>
<enabled>true</enabled>
</snapshots>
<releases>
<enabled>true</enabled>
</releases>
</pluginRepository>
</pluginRepositories>

<build>
<finalName>my-webapp</finalName>
<plugins>

<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>tomcat-maven-plugin</artifactId>
<version>1.0-SNAPSHOT</version>
</plugin>

</plugins>

</build>
</project>

Answer 1

It looks like the redirection is incorrect, Codehaus Snapshots are proxied by: https://nexus.codehaus.org/content/repositories/codehaus-snapshots/.

So declare the following pluginRepository to use SNAPSHOT versions of the tomcat-maven-plugin:

<pluginRepositories>
  <pluginRepository>
    <id>Codehaus Snapshots</id>
    <url>https://nexus.codehaus.org/content/repositories/codehaus-snapshots&lt;/url&gt;
  </pluginRepository>
</pluginRepositories>
