Howto get rid of [WARNING] Deprecated API called in maven site

I like to get rid of the following warning while calling mvn site:site on a project

[INFO] Generating "About" report. 
[WARNING] Deprecated API called - not org.apache.maven.doxia.sink.Sink instance and no SinkFactory available. Please update this plugin.

The part of my pom looks like this:

  <reporting>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-project-info-reports-plugin</artifactId>
        <version>2.4</version>
        <reportSets>
          <reportSet>
            <reports>
              <report>index</report>
              <report>cim</report>
              <report>issue-tracking</report>
              <report>license</report>
              <report>scm</report>
            </reports>
          </reportSet>
        </reportSets>
      </plugin>

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-site-plugin</artifactId>
        <version>2.4</version>
      </plugin>            
    </plugins>
  </reporting>

My mvn --version returns the following output:

Apache Maven 2.2.1 (r801777; 2009-08-06 21:16:01+0200)
Java version: 1.6.0_10
Java home: /opt/jdk1.6.0_10/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux" version: "2.6.32-41-generic" arch: "i386" Family: "unix"

Unluckily I'm unable to find the correct plugin that cries for an update. Updating/Migrating to maven-3.x is not an option at the moment.

Solution

  • I had the same problem last week. The problem its on the maven-site plugin which is not using the correct version. This is what I did:

    pom.xml:

    <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-project-info-reports-plugin</artifactId>
    <version>2.1.1</version>
</plugin>
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-site-plugin</artifactId>
    <version>3.1</version>
</plugin>

    Finally to select the reports, I use the <reports> section:

    <project>
...
<plugins>
<reporting>
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-project-info-reports-plugin</artifactId>
    <version>2.5</version>
    <reportSets>
      <reportSet>
         <reports>
       <report>index</report>
       <report>project-team</report>
           <report>issue-tracking</report>
       <report>summary</report>
     </reports>
      </reportSet>
    </reportSets>
</plugin>
</plugins>
</reporting>
...
</project>
