The plugin properties are injected at runtime from the project they run on. The properties defined in the plugin's pom are used to build the plugin not run it. You could do this, just in a different way. Make a property file in your plugin project and filter the value into it. Then when your plugin runs you can read this property.

I am developing a custom plugin that contains a Mojo that doesn't requires a project. The Mojo is invoked from an empty working directory. What the Mojo does is get a parameter defined in the plugin's POM and print it to the log. The problem is that I don't know how to pass this parameter to the Mojo. Here is an example: In the Mojo class I define the member param to be injected with the value of a parameter called myParam. /** * @parameter expression="${myParam}" */ private String param; When the Mojo executes it suppose to print the parameter's value public void execute() throws MojoExecutionException, MojoFailureException { getLog().info("Param value is: " + param); } In the plugin's POM I define the parameter <project...> ... <properties> <myParam>Hello World!</myParam> </properties> ... </project> The plugin is installed in the local repository. When I invoke the Mojo I get the following message: [0] Inside the definition for plugin 'maven-myplugin-plugin' specify the following: <configuration> ... <myParam>VALUE</myParam> </configuration> -OR- on the command line, specify: '-DmyParam=VALUE' I tried to include my plugin in the plugins section in the POM of the plugin itself (some kind of crazy recursive inclusion) as follows: <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-myplugin-plugin</artifactId> <configuration> <myParam>Hello World!</myParam> </configuration> </plugin> but I still get the same message. If I invoke the plugin from a working directory that contains a pom.xml file the defines this parameter the Mojo executes successfully. Does anyone know how to define a parameter in a custom plugin and use the value of this parameter in the Mojos of the plugin?
