Maven failure to find codehaus artifact org.codehaus:codehaus-parent

Question

So codehaus shut down (over the weekend, apparently): https://www.codehaus.org/

Now it says here that "Maven: All repositories are mirrored into Central, and our Nexus is hosted by Sonatype". If I am reading this correctly, this means that it should continue to work (and because Central is the default repository, I shouldn't even have any changes to make).

Yet I am having trouble with a Maven project that used to compile (before the shutdown), but now fails:

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

Project ID: org.codehaus.groovy:groovy-eclipse-compiler:maven-plugin:2.9.1-01
Reason: Cannot find parent: org.codehaus:codehaus-parent for project: org.codehaus.groovy:groovy-eclipse-compiler:maven-plugin:2.9.1-01 for project org.codehaus.groovy:groovy-eclipse-compiler:maven-plugin:2.9.1-01

Here's a trimmed-down version of my pom.xml:

Now, in my .m2 directory I find for the groovy-all project a pom/sha1, and a jar file. But for groovy-eclipse-compiler , I see the pom/sha1, but no jar file .

Am I doing something wrong? Did something in the Codehaus migration itself get screwed up somehow? Or (worse) both?

Answer 1

The maven artifacts are in central for a long time already, there is no migration that could have been screwed up for those.

Since I am no maven expert I can give you only what I assume is the cause. Looking at the pom for version 2.9.1-01 of the groovy-eclipse-compiler I see

<repositories>
    <repository>
        <id>codehaus.org</id>
        <url>http://repository.codehaus.org</url>
    </repository>
</repositories>

ans my assumption is, that this will cause maven to look in that repository, which does not exist anymore. If that is true, then my suggestion for a solution would be to manually install the artifacts (they are all on maven central) or to use a different tool like gradle (though that might be out of scope for you) to do the build.

EDIT: I have been told that you could change your settings.xml to fix repository configurations with a pattern like this:

<repositories>
    <repository>
        <id>codehaus.org</id>
        <url>http://nexus.codehaus.org/<some suburl></url>
    </repository>
</repositories>

Using http://mvnrepository.com/artifact for example might then work, but I have not tested this.

Answer 2

The artifact you are referencing to:

org.codehaus.groovy:groovy-eclipse-compiler:maven-plugin:2.9.1-01

if this isn't being found by your build than simply your configuration is wrong. Either network/proxy issues etc. (see your settings.xml) You can search this artifact in Maven central via: http://search.maven.org/#search%7Cgav%7C1%7Cg%3A%22org.codehaus.groovy%22%20AND%20a%3A%22groovy-eclipse-compiler%22

Apart from that adding supplemental repositories this does not help. Furthermore adding default's in a Maven pom like this:

  <resources>
    <resource>
      <directory>src/main/resources</directory>
    </resource>
  </resources>
  <testResources>
    <testResource>
      <directory>src/test/resources</directory>
    </testResource>
  </testResources>

does not make sense either, cause these are the defaults. What i stumbled over as well is that you are defining things like the encoding:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-resources-plugin</artifactId>
  <version>2.6</version>
  <configuration>
    <encoding>UTF-8</encoding>
  </configuration>
</plugin>

First it is good to define the version of plugins like this (but you should use uptodate versions ) but you should not define the encoding in every plugin. For such purposes a property exist:

<project>
  ...
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>
  ...
</project>

by using the above you don't need to give the encoding for every plugin, cause the plugins like maven-resources-plugin , maven-compiler-plugin etc. define a default.

A word about the codehaus migration . This means only the services they have offered for developers are shutting down but not the content which already is part for Maven central.

I would recommend to install a repository manager in your own infrastructure.
