Maven Dependencies can't be resolved

Question

I'm using Apache Maven3 and since two or three days some dependencies can't be resolved any more, which first have not had a problem. To be more specific its:

1. maven-findbgs-plugin:plugin:1.3.1
2. maven-cobertura-plugin:plugin:1.3

Shouldn't they be included by maven itself?

My pom.xml file:

Any help is highly apprechiated.

Answer 1

For those who try to fix it with Ivy. This one worked for me:

<dependency org="jaxen" name="jaxen" rev="1.1.4"/>
<dependency org="net.sourceforge.cobertura" name="cobertura" rev="1.9.4.1"/>
<dependency org="com.google.code.findbugs" name="findbugs" rev="2.0.1"/>
<dependency org="org.jdom" name="jdom" rev="2.0.2">
  <exclude module="jaxen"/>
  <exclude name="maven-cobertura-plugin"/>
  <exclude name="maven-findbugs-plugin"/>
</dependency>

Answer 2

You can use the POM editor in Eclipse to see the dependency graph. It quickly showed my that jaxen-1.1.3 includes old maven1 dependencies. Eclipse even offers excluding them on the spot. Nice.

Answer 3

Look in your local repository (normaly in <home>/.m2), where the artifacts should be. You'll find <artifactname>.lastUpdated files there. delete those and try again.

Possibly the artifacts failed to load due to network problems and now aren't even checked.

Answer 4

You should add those two plugins to your pom.

For cobertura, see this page.

For findbugs, see this page.

----- UPDATED -----

OK, I found the problem. It appears that you depend on jdom 1.1.2, which depends on jaxen 1.1.3 of which artifact is broken.

You can either try another jdom version or add to your pom the snapshot described in this site. Worked for me when I ran your pom on my PC. I copied the snapshot:

<dependency>
  <groupId>jaxen</groupId>
  <artifactId>jaxen</artifactId>
  <version>1.1.3</version>
  <!-- http://jira.codehaus.org/browse/JAXEN-217 -->
  <exclusions>
    <exclusion>
      <groupId>maven-plugins</groupId>
      <artifactId>maven-cobertura-plugin</artifactId>
    </exclusion>
    <exclusion>
      <groupId>maven-plugins</groupId>
      <artifactId>maven-findbugs-plugin</artifactId>
    </exclusion>
  </exclusions>
</dependency>
