Maven checkstyle插件。 CheckstyleException：模塊Para​​meterName中的屬性'accessModifiers'不存在

Question

我試圖將checkstyle插件與名爲checkstyle.xml的自定義checkstyle文件一起使用。 I have followed the guide。這是我的POM：

... 
<reporting> 
    <plugins> 
     <plugin> 
      <groupId>org.apache.maven.plugins</groupId> 
      <artifactId>maven-checkstyle-plugin</artifactId> 
      <version>2.17</version> 
      <configuration> 
       <configLocation>src/main/resources/checkstyle.xml</configLocation> 
      </configuration> 
      <reportSets> 
       <reportSet> 
        <reports> 
         <report>checkstyle</report> 
        </reports> 
       </reportSet> 
      </reportSets> 
     </plugin> 
    </plugins> 
</reporting> 
... 

和checksyle.xml是the google checkstyle file（我只重命名的文件）。問題是，當我運行mvn -X site，我得到了以下錯誤：

我檢查了CheckStyle的文件，我已經定義了accessModifiers屬性。

.... 
<module name="ParameterName"> 
    <property name="id" value="ParameterNameNonPublic"/> 
    <property name="format" value="^[a-z]([a-z0-9][a-zA-Z0-9]*)?$"/> 
    <property name="accessModifiers" value="protected, package, private"/> 
    <message key="name.invalidPattern" value="Parameter name ''{0}'' must match pattern ''{1}''."/> 
</module> 
<module name="ParameterName"> 
    <property name="id" value="ParameterNamePublic"/> 
    <property name="format" value="^[a-z][a-z0-9][a-zA-Z0-9]*$"/> 
    <property name="accessModifiers" value="public"/> 
    <message key="name.invalidPattern" value="Parameter name ''{0}'' must match pattern ''{1}''."/> 
</module> 

所以，我不知道我在做什麼錯。

Answer 1

accessModifiers僅在checkstyle版本7.5中引入。請參閱下面的發行說明。 http://checkstyle.sourceforge.net/releasenotes.html

1. 可以使模塊定義由 與舊版本兼容去除accessModifiers和添加範圍來代替。
2. 您可以（通過defualt其6.11.2）
