            </plugin>
        </plugins>

    </build>
</project>

I've tried following things so far to eliminate this error, havent got any success yet.

1.DownGraded the JDK from  Version 1.7 to jdk1.6.0_18

2.Added the **main class** in the **plugin for org.codehaus.mojo**

          <configuration>
            <mainClass>C:\apache-camel-2.11.0\examples\camel-example-smooks-integration\src\main\java\example\Main</mainClass>
        </configuration>

Answer 1

I had a similar problem with 'org.codehaus.mojo'-'jaxws-maven-plugin': could not resolve dependencies. Fortunately, I was able to do a Project > Clean in Eclipse, which resolved the issue.

Answer 2

I had a similar problem.

As it turned out, I ran mvn clean package install.

Correct way is mvn clean install

Answer 3

Your problem is that you have declare twice the exec-maven-plugin :

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.2.1</version>
    <executions>
        <execution>
            <goals>
                <goal>java</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <mainClass>C:\apache-camel-2.11.0\examples\camel-example-smooks-  
      integration\src\main\java\example\Main< /mainClass>
    </configuration>
</plugin>

...

< plugin>
    < groupId>org.codehaus.mojo</groupId>
    < artifactId>exec-maven-plugin</artifactId>
    < version>1.2</version>
< /plugin>

Answer 4

I had the same problem but after deleting the old plugin for org.codehaus.mojo it worked.

I use this

        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>exec-maven-plugin</artifactId>
            <version>1.2</version>
        </plugin>
