如何在maven中配置checkstyle？

Question

我正在使用Maven
我有一个父模块和一些其他模块.他们看着像是:

PARENT
??? pom.xml
??? ModulA
|   ??? pom.xml
??? ModulB
    ??? pom.xml
    ??? folder
        ??? checkstyle.xml

我试图用自己的规则替换规则.但它忽略了我的规则.我将插件添加到父pom.xml中

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-checkstyle-plugin</artifactId>
    <version>2.9.1</version>
    <configuration>
        <includeTestSourceDirectory>true</includeTestSourceDirectory>
        <configLocation>
            ${basedir}/../ModulB/folder/checkstyle.xml                  
        </configLocation>
    </configuration>
</plugin>

问题出在哪儿？

mvn checkstyle:checkstyle -X

      <cacheFile default-value="${project.build.directory}/checkstyle-cachefile"/>

      <xrefLocation default-value="${project.reporting.outputDirectory}/xref"/>
    </configuration>

要获取自定义配置,您需要将文件声明为属性:

<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/xsd/maven-4.0.0.xsd">
  ...

  <properties>
    <checkstyle.config.location><!-- file location --></checkstyle.config.location>
  </properties>

  <build>
    ...

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-checkstyle-plugin</artifactId>
        <version>2.9.1</version>
      </plugin>
    </plugins>
  </build>

</project>

为什么你不将 checkstyle 配置放在父项目的目录中，并像src/main/resources这样在父 pom.xml 中参数化插件

<!-- Checkstyle -->
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-checkstyle-plugin</artifactId>
    <version>RELEASE</version>
    <configuration>
        <configLocation>src/main/resources/checkstyle.xml</configLocation>                   
    </configuration>
</plugin>

子项目应该有权执行此配置
