Solution 1:

I had same problem with Eclipse 3.7.2 (Indigo) and maven 3.0.4.

In my case, the problem was caused by missing maven-resources-plugin-2.4.3.jar in {user.home}\.m2\repository\org\apache\maven\plugins\maven-resources-plugin\2.4.3 folder. (no idea why maven didn't update it)

Solution:

1.) add dependency to pom.xml

<dependency>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>2.4.3</version>
</dependency>

2.) run mvn install from Eclipse or from command line

3.) refresh the project in eclipse (F5)

4.) run Maven > Update Project Configuration... on project (right click)

JAR file is downloaded to local repository and there are no errors in WS.

Solution 2:

I also had same problem with Eclipse 3.7.2 (Indigo) and maven 3.0.4.

Eclipse wasn't picking up my maven settings, so this is what I did to fix the problem:

  1. Window - Preferences - Maven - Installations

    • Add (Maven 3.0.4 instead of using Embedded)
    • Click Apply & OK
  2. Maven > Update Project Configuration... on project (right click)

  3. Shutdown Eclipse

  4. Run mvn install from the command line.

  5. Open Eclipse

Those steps worked for me, but the problem isn't consistent. I've only had with issue on one computer.
