maven-checkstyle-plugin - checkstyle 不获取 src/test 文件夹

Question

我在 maven 构建中添加了 checkstyle 但由于某种原因它只检查 src/main 文件夹并忽略 src/test 文件夹，这是我的项目结构:

Proj
 - Module A
   - src
     - main
       - java
       - resources
     - test
       - java
       - resources
 - Module B
   - src
     - main
       - java
       - resources
     - test
       - java
       - resources
 pom.xml
 checkstyle.xml

和我的 pom.xml

     <properties>
        <checkstyle.version>3.0.0</checkstyle.version>
        <checkstyle.config.location>checkstyle.xml</checkstyle.config.location>
        <checkstyle.consoleOutput>true</checkstyle.consoleOutput>
        <checkstyle.failOnViolation>true</checkstyle.failOnViolation>
        <encoding>UTF-8</encoding>
    </properties>

         <includeTestSourceDirectory>true</includeTestSourceDirectory>

                            </goals>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </pluginManagement>
    </build>

在<plugin>下方设置配置标签，像这样:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-checkstyle-plugin</artifactId>
    <version>3.1.0</version>
    <dependencies>
        <dependency>
            <groupId>com.puppycrawl.tools</groupId>
            <artifactId>checkstyle</artifactId>
            <version>8.27</version>
        </dependency>
    </dependencies>
    <configuration>
        <configLocation>checkstyle.xml</configLocation>
        <includeTestSourceDirectory>true</includeTestSourceDirectory>
    </configuration>
</plugin>
