I tried to delete repositories and install again. I got this error always. It looks like I need help. I think my mojo plugin is broken but i re installed it several times. Any suggestions?

Answer 1

Try to delete the maven folder at ~/.m2/repository/org/apache/maven and build your project again to force the maven libraries be downloaded. This worked for me the last time I faced this java.lang.NoClassDefFoundError: org/apache/maven/shared/filtering/MavenFilteringException.

Answer 2

This should fix the error

<plugin>
     <groupId>org.apache.maven.plugins</groupId>
     <artifactId>maven-resources-plugin</artifactId>
     <version>2.7</version>
     <dependencies>
         <dependency>
             <groupId>org.apache.maven.shared</groupId>
             <artifactId>maven-filtering</artifactId>
             <version>1.3</version>
          </dependency>
      </dependencies>
</plugin>

Answer 3

You should add maven-resources-plugin in your pom.xml file. Deleting ~/.m2/repository does not work always.

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

Now build your project again. It should be successful!

Answer 4

Does the class org.apache.maven.shared.filtering.MavenFilteringException exist in file:/C:/Users/utopcu/.m2/repository/org/apache/maven/shared/maven-filtering/1.0-beta-2/maven-filtering-1.0-beta-2.jar?

The error message suggests that it doesn't. Maybe the JAR was corrupted somehow.

I'm also wondering where the version 1.0-beta-2 comes from; I have 1.0 on my disk. Try version 2.3 of the WAR plugin.

Answer 5

Faced the same issue and resolved by upgrading my Maven from 3.0.4 to 3.1.1. Please try with v3.1.1 or any higher version if available

Answer 6

this happened to me too after adding the version tag, that was missing, to the maven-war-plugin (not sure what version was using by default, i changed to the latest, 2.6 in my case). I had to wipe .m2/repository to have the build succeed again.

I tried first to clean the maven-filtering folder (in the repo) but then instead of a MavenFilterException i was getting an ArchiverException. So i concluded the local repository was corrupted (for a version upgrade?) and i deleted everything.

That fixed it for me. Just clean your local repo.
