How do you properly execute "mvn clean" inside a project?

Question

I'm trying to clean, build, and package my project, but I keep getting this error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-clean-plugin:2.6.1:clean (auto-clean) on project Presentation: Unable to parse configuration of mojo org.apache.maven.plugins:maven-clean-plugin:2.6.1:clean for parameter retryOnError: Cannot find 'retryOnError' in class org.apache.maven.plugin.clean.CleanMojo -> [Help 1]

I've been trying to figure this out for myself for a while now. I have the project set up to auto clean, and it's exactly how Apache instructed to do so in the pom file(s), but I'll include that as well.

<project>
    <build>
        ...
        <plugin>
            <artifactId>maven-clean-plugin</artifactId>
            <version>2.6.1</version>
            <configuration>
                <failOnError>false</failOnError>
            </configuration>
            <executions>
                <execution>
                    <id>auto-clean</id>
                    <phase>initialize</phase>
                    <goals>
                        <goal>clean</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
        ...
    </build>
<project>

I am lost here. Obviously, it has something to do with 'retryOnError', but that's not something I added myself. Where would I find that?

Also, I'm using Maven 3.2.5 if that helps.

@ɐuıɥɔɐɯ is right.

I would also try removing the auto-clean plugin configuration in your pom.xml, as it may be more work to figure out why it is causing problems than it is worth. For now on, I would simply run the following command in the root folder of your project:

mvn clean package

That should run your goals listed in your pom.xml, and clean your "target" subdirectory, replacing it with the newest code.
