Maven: apply plugin only to one of several modules

Question

I'm building my project using the following POM:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"&gt;
<modelVersion>4.0.0</modelVersion>
<groupId>build.local</groupId>
<artifactId>build-local</artifactId>
<packaging>pom</packaging>
<name>${project.artifactId}</name>
<version>0-SNAPSHOT</version>
<description></description>
<inceptionYear>2009</inceptionYear>
<modules>
 <module>module1</module>
 <module>module2</module>
</modules>
<build>
    <pluginManagement>
     <plugins>
      <plugin>
       <groupId>org.codehaus.mojo</groupId>
       <artifactId>buildnumber-maven-plugin</artifactId>
       <version>1.0-beta-2</version>
      </plugin>
     </plugins>
    </pluginManagement>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>exec-maven-plugin</artifactId>
            <version>1.1.1</version>
            <configuration>
                <executable>deploy.bat</executable>
            <configuration>
        </plugin>
    </plugins>
</build>
</project>

The build works fine. The deployment using the plugin works as well. The only problem I have: maven calls deploy.bat twice, once for every module. However, I only need it executed once. How can I do that?

Answer 1

You can just put the plugin in one of your modules.

Answer 2

Move the < plugin >...< /plugin > directive in to the module1/pom.xml file.

Answer 3

Referencing this http://maven.apache.org/ref/2.2.1/maven-model/maven.html ... ... set inherited value to false (default is true) and childs projects will not inherit the plugin.
