Subject [jira] Created: (MNG-5022) Unable to use a Mojo with a setter
Date Tue, 22 Feb 2011 13:31:23 GMT
Unable to use a Mojo with a setter
----------------------------------

                 Key: MNG-5022
                 URL: http://jira.codehaus.org/browse/MNG-5022
             Project: Maven 2 & 3
          Issue Type: Bug
          Components: Documentation:  General, Plugin API, Plugin Requests, Plugins and Lifecycle
    Affects Versions: 2.2.1
         Environment: $ mvn -version
Apache Maven 2.2.1 (r801777; 2009-08-06 21:16:01+0200)
Java version: 1.6.0_22
Java home: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
Default locale: en_US, platform encoding: MacRoman
OS name: "mac os x" version: "10.6.4" arch: "x86_64" Family: "mac"

            Reporter: wolfgang häfelinger
            Priority: Critical


According to documentation (Maven Book, p405), the following example should work ("You can
also use these annotations on public setter methods, [..]").

/**
 * @goal echo
 * @requiresProject false
 */
public class EchoMojo extends AbstractMojo {
	private String msg;
	
	/**
	 * @parameter expression="${echo.message}" 
	 */
	public void setMessage(String message) {
		this.msg = message;
	}
	
	public void execute() throws MojoExecutionException,MojoFailureException {
		getLog().info("what now??");
		getLog().info(msg);
		getLog().info("<>");
	}
}

It does not work.

The generated plugin.xml states, that there are *no* parameters for this Mojo:
== plugin.xml ==
..
    <mojo>
      <goal>echo</goal>
      <description></description>
      <requiresDirectInvocation>false</requiresDirectInvocation>
      <requiresProject>false</requiresProject>
      <requiresReports>false</requiresReports>
      <aggregator>false</aggregator>
      <requiresOnline>false</requiresOnline>
      <inheritedByDefault>true</inheritedByDefault>
      <implementation>org.epo.common.maven.plugins.epo.EchoMojo</implementation>
      <language>java</language>
      <instantiationStrategy>per-lookup</instantiationStrategy>
      <executionStrategy>once-per-session</executionStrategy>
      <threadSafe>false</threadSafe>
      <parameters/>
    </mojo>
..
