Quickstart Guide

Configuring the plugin

Add the following in the <plugins> list of your project's pom.xml file:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-enforcer-plugin</artifactId>
    <dependencies>
        <dependency>
            <groupId>com.github.mikkoi</groupId>
            <artifactId>maven-enforcer-rule-depend-on-all-projects</artifactId>
            <version>0.0.15</version>
        </dependency>
    </dependencies>
    <executions>
        <execution>
            <id>depend-on-all-projects</id>
            <phase>validate</phase>
            <goals>
                <goal>enforce</goal>
            </goals>
            <configuration>
                <rules>
                    <dependOnAllProjects/>
                </rules>
            </configuration>
        </execution>
    </executions>
</plugin>

Another configuration example with separate <pluginManagement> definition:

<project>
    <build>
        <pluginManagement>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-enforcer-plugin</artifactId>
                    <version>3.6.1</version>
                    <dependencies>
                        <dependency>
                            <groupId>com.github.mikkoi</groupId>
                            <artifactId>maven-enforcer-rule-depend-on-all-projects</artifactId>
                            <version>@project.version@</version>
                        </dependency>
                    </dependencies>
                </plugin>
            </plugins>
        </pluginManagement>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-enforcer-plugin</artifactId>
                <configuration>
                    <rules>
                        <dependOnAllProjects>
                            <!-- Include all projects with same groupId -->
                            <!-- except pom projects and one web application -->
                            <includes>
                                <include>com.github.mikkoi:*</include>
                            </includes>
                            <excludes>
                                <exclude>com.github.mikkoi:*:pom</exclude>
                                <exclude>com.github.mikkoi:not-me:war</exclude>
                            </excludes>
                        </dependOnAllProjects>
                    </rules>
                </configuration>
            </plugin>
        </plugins>
    </build>

</project>
