如何在Maven构建中使用较旧的Checkstyle版本？

我将Maven项目与现有的自定义Checkstyle规则集合在一起，编译为jar并在Nexus存储库中提供。规则集对Checkstyle 5.0有依赖性，并且与新版本不兼容。如何在Maven构建中使用较旧的Checkstyle版本？

我在配置Maven时使用这个较旧的Checkstyle版本和我的规则时遇到了问题。

这里是我的项目布局：

root/ 
    pom.xml 
    buildsupport/ 
    pom.xml 
    src/main/resources/checkstyle 
     mycompany-coding-rules.xml 
    src/main/java/com.mycompany.checkstyletest/ 
     CheckstyleViolator.java 
    [other projects with pom.xml and java source...]

这是我的父母pom.xml：

<project> 
... 
<build> 
    <pluginManagement> 
     <plugins> 
      <plugin> 
       <groupId>org.apache.maven.plugins</groupId> 
       <artifactId>maven-checkstyle-plugin</artifactId> 
       <version>2.5</version> 
      </plugin> 
     </plugins> 
    </pluginManagement> 
<plugins> 
    ... 
    <plugin> 
     <groupId>org.apache.maven.plugins</groupId> 
     <artifactId>maven-site-plugin</artifactId> 
     <version>3.0</version> 
     <dependencies> 
      <dependency> 
       <groupId>com.mycompany</groupId> 
       <artifactId>buildsupport</artifactId> 
       <version>X.Y.Z</version> 
      </dependency> 
      <dependency> 
       <groupId>checkstyle</groupId> 
       <artifactId>checkstyle</artifactId> 
       <version>5.0</version> 
      </dependency> 
      <dependency> 
       <groupId>com.mycompany.checkstyle</groupId> 
       <artifactId>mycompany-checkstyle</artifactId> 
       <version>1.1</version> 
      </dependency> 
     </dependencies> 
    </plugin> 
</plugins> 
</build> 

<reporting> 
    <plugins> 
     <plugin> 
      <groupId>org.apache.maven.plugins</groupId> 
      <artifactId>maven-checkstyle-plugin</artifactId> 
      <version>2.5</version> 
      <configuration> 
       <configLocation>checkstyle/mycompany-coding-rules.xml</configLocation> 
       <packageNamesLocation>checkstyle_packages.xml</packageNamesLocation> 
      </configuration> 
     </plugin> 
    </plugins> 
</reporting> 
...

如果我忽略从Maven的的CheckStyle-插件<version>2.5</version>在<reporting><plugins><plugin>...和<build><pluginManagement><plugins><plugin>，并运行mvn site在根目录中，我得到顶级项目的失败：

... 
[INFO] Generating "Checkstyle" report --- maven-checkstyle-plugin:2.8 
... 
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-site-plugin:3.0:site (default-site) on project mytoplevel-project: 
Error during page generation: Error rendering Maven report: Failed during checkstyle configuration: 
cannot initialize module TreeWalker - TreeWalker is not allowed as a parent of com.mycompany.checkstyle.checks.coding.ImportOrderCheck -> [Help 1]

添加<version>2.5</version>在上面的XML允许顶级项目成功，但同样的错误是出现在第一个孩子的项目：

... 
[INFO] Generating "Checkstyle" report --- maven-checkstyle-plugin:2.5 
... 
[INFO] mytoplevel-project ................................ SUCCESS [4.528s] 
[INFO] buildsupport ...................................... FAILURE [0.489s] 
... 
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-site-plugin:3.0:site (default-site) on project buildsupport: 
Error during page generation: Error rendering Maven report: Failed during checkstyle configuration: 
cannot initialize module TreeWalker - TreeWalker is not allowed as a parent of com.mycompany.checkstyle.checks.coding.ImportOrderCheck -> [Help 1]

我敢肯定这个错误是由于最新当使用规则集作为针对Checkstyle 5.5的Eclipse插件时，我看到了同样的错误 - 它通过将Checkstyle插件版本回滚到5.0来修复。

我不明白的是孩子项目如何挑选错误的Checkstyle版本。

的问题是，TeamCity XML Reporting无法解析之前的Checkstyle报告给CHECKSTYLE 5.1，所以没有这种帮助我！
