Maven not able to find setter for MavenProjectHelper property
-------------------------------------------------------------
Key: MNG-1465
URL: http://jira.codehaus.org/browse/MNG-1465
Project: Maven 2
Type: Bug
Reporter: David Jackman
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
