Question

所以我目前正在为maven / java项目实现checkstyle。由于我公司的项目复杂而又庞大，我从一个较小的项目开始，只是为了测试它是否有效。到目前为止，执行情况很好。我设置好我的checkstyle.xml并将其连接到pom.xml，全部完成了。同样在报告部分，因为我之后需要一些输出。问题是，正如您从标题中可以看出的那样，它想以某种方式解析某些内容，但是我什至无法访问这些文件。

CheckStyle.xml :
    <!DOCTYPE module PUBLIC
      "-//Puppy Crawl//DTD Check Configuration 1.3//EN"
      "http://www.puppycrawl.com/dtds/configuration_1_3.dtd">
    <module name="Checker">
        <module name="TreeWalker">
            <module name="AvoidStaticImport">
                <property name="excludes" 
    value="java.lang.System.out,java.lang.Math.*" />
            </module>
        </module>
    </module>
     <module name="ImportOrder">
       <property name="groups" value="*,javax,java"/>
       <property name="ordered" value="true"/>
       <property name="separated" value="false"/>
       <property name="option" value="top"/>
       <property name="sortStaticImportsAlphabetically" value="true"/>
 </module>
 <module name="SuppressionXpathSingleFilter">
   <property name="checks" value="ImportOrder"/>
   <property name="message" value="^'java\..*'.*"/>
 </module>

pom.xml :
<build>

I really dont know what else to do, thanks in advance for any help.


I get the checkstyle-result.xml but its empty. before i got a empty xml template back (so it worked, without any todos) 
But i still expected a checkstyle.html file for the report.

您的checkstyle.xml格式不正确。格式正确的XML文档只有一个根元素。您应该像这样将ImportOrder和SuppressionXpathSingleFilter模块放在TreeWalker下：

<!DOCTYPE module PUBLIC
    "-//Puppy Crawl//DTD Check Configuration 1.3//EN"
    "http://www.puppycrawl.com/dtds/configuration_1_3.dtd">
<module name="Checker">
  <module name="TreeWalker">
    <module name="AvoidStaticImport">
      <property name="excludes" value="java.lang.System.out,java.lang.Math.*"/>
    </module>
    <module name="ImportOrder">
      <property name="groups" value="*,javax,java"/>
      <property name="ordered" value="true"/>
      <property name="separated" value="false"/>
      <property name="option" value="top"/>
      <property name="sortStaticImportsAlphabetically" value="true"/>
    </module>
    <module name="SuppressionXpathSingleFilter">
      <property name="checks" value="ImportOrder"/>
      <property name="message" value="^'java\..*'.*"/>
    </module>
  </module>
</module>
