Maven Exec Plugin not reading configuration

maven-2, maven-plugin

Solution

I see one issue with your code. You need to put -jar into its own `argument` element. You will get an error if you don't. The rest of your code is dead on acurate. Here is a working example from one of my projects. This executes a jar that is packaged in the target directory after executing `mvn package`. If you still get the same error I would try deleting the plugin from your local repository to get a fresh copy. Also ensure that the plugin is not in the `pluginsManagement` element. If that fails, post your entire POM.

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.1.1</version>
    <executions>
        <execution>
            <goals>
                <goal>exec</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <executable>java</executable>
        <workingDirectory>/target</workingDirectory>            
        <arguments>
            <argument>-jar</argument>
            <argument>${project.build.directory}/${project.build.finalName}.jar</argument>
        </arguments>          
    </configuration>
</plugin>

Problem

I'm trying to execute my project using the Maven exec:exec goal and I've tried to configure it with this snippet: ``` <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>exec-maven-plugin</artifactId> <version>1.1.1</version> <configuration> <executable>java</executable> <arguments> <argument>-jar ${staging.dir}/project.jar</argument> </arguments> </configuration> <executions> <execution> <goals> <goal>exec</goal> </goals> </execution> </executions> </plugin> ``` When I run `mvn exec:exec` I get the output: ``` ------------------------------------------------------------------------ [ERROR]BUILD ERROR ------------------------------------------------------------------------ One or more required plugin parameters are invalid/missing for 'exec:exec' [0] Inside the definition for plugin 'exec-maven-plugin' specify the following: <configuration> ... <executable>VALUE</executable> </configuration> -OR- on the command line, specify: '-Dexec.executable=VALUE' ``` I've tried reorganising the `<plugin>` everyway I can think of but nothing makes any difference? The project is a POM not a jar. Any ideas?
