[jira] Updated: (MNG-1465) Maven not able to find setter for

[ http://jira.codehaus.org/browse/MNG-1465?page=all ]
Jason van Zyl updated MNG-1465:
-------------------------------

> Project: Maven 2
> Type: Bug

> This might really be a plexus issue (I don't know enough about the code to know for sure).
> I have a Mojo class with a field of type MavenProjectHelper. For all other field, I've followed the pattern of using a private member field with a prefix of "m_", then using the property parameter to indicate a setter method for that field that Maven should use. This seems to work find for most of my properties, but the one that takes a MavenProjectHelper won't work that way. For some reason, it looks for a field of that name and not a setter method for that property.
> Here's the field definition and the setter method:
> /**
> * @parameter expression="${component.org.apache.maven.project.MavenProjectHelper}" property="projectHelper"
> */
> private MavenProjectHelper m_projectHelper;
> /**
> * Sets the project helper.
> *
> * @param projectHelper the project helper to use.
> */
> public void setProjectHelper(MavenProjectHelper projectHelper)
> {
> this.m_projectHelper = projectHelper;
> }
> And the error I get back when attempting to use the Mojo looks like this:
> [INFO] Internal error in the plugin manager executing goal 'no.fast.buildprocess:docextractor:1.0-SNAPSHOT:configdocjar': Unable to find the mojo 'no.fast.buildprocess:docextractor:1.0-SNAPSHOT:configdocjar' in the plugin 'no.fast.buildprocess:docextractor'
