Couldn't run build using Maven because of an error in pom.xml

Question

I am trying to build a new Maven project in Eclipse. In my pom.xml, I got an error which says

Multiple annotations found at this line: - Missing artifact maven-plugins:maven-findbugs-plugin:plugin:1.3.1 - Missing artifact maven-plugins:maven-cobertura-plugin:plugin:1.3

Here is my dependency code for "cobertura" in pom.xml:

   <dependency>
        <groupId>maven-plugins</groupId>
        <artifactId>maven-cobertura-plugin</artifactId>
        <version>1.3</version>
        <type>plugin</type>
    </dependency>

I tried adding repositories as below, but still didn't work.

  <repositories>
    <repository>
        <id>repository.maven-plugins.sourceforge.net</id>
        <name>maven plug-in repository</name>
        <url>http://maven-plugins.sourceforge.net/repository</url>
    </repository>
    <repository>
        <id>repository.ibiblio.org-maven</id>
        <name>ibiblio repository</name>
        <url>http://www.ibiblio.org/maven</url>
    </repository>
</repositories>

Links to Maven plugins here
http://maven-plugins.sourceforge.net/maven-findbugs-plugin/announcements/announcement-1.3.1.txt

http://maven-plugins.sourceforge.net/maven-cobertura-plugin/announcements/announcement-1.3.txt

I don't want to do Manual installation for these plugins. I need to install them automatically by declaring them in pom.xml

Please help.

Thanks

Solution

As a related issue, I found that e.g. jaxen-1.1.3 references the above maven1 artifacts. The POM editor in Eclipse shows you the dependency hierarchy. It added the following for selecting explicit excludes:

    <dependency>
        <groupId>jaxen</groupId>
        <artifactId>jaxen</artifactId>
        <version>1.1.3</version>
        <exclusions>
            <exclusion>
                <artifactId>maven-cobertura-plugin</artifactId>
                <groupId>maven-plugins</groupId>
            </exclusion>
            <exclusion>
                <artifactId>maven-findbugs-plugin</artifactId>
                <groupId>maven-plugins</groupId>
            </exclusion>
        </exclusions>
    </dependency>

This does not work, because jaxen explicitly demands cobertura 1.3 and findbugs 1.3.1.

Also jdom 1.1.2 includes jaxen 1.1.3 which imports those artifacts. The same fix applies into jdom dependency. Thank you!
