php - 在phpmd中为规则设置异常(exception)

我试图在phpmd中为一个规则设置一个异常，允许一个特定的函数名只有两个字符的长度
前一个phpmd.xml.dist文件工作得非常愉快：

<?xml version="1.0" encoding="UTF-8" ?>
<ruleset name="Complex PHP Mess Detector Rule Set"
    xmlns="http://pmd.sf.net/ruleset/1.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://pmd.sf.net/ruleset/1.0.0 http://pmd.sf.net/ruleset_xml_schema.xsd"
    xsi:noNamespaceSchemaLocation="http://pmd.sf.net/ruleset_xml_schema.xsd">
    <rule ref="rulesets/naming.xml">
        <exclude name="LongVariable" />
    </rule>
    <rule ref="rulesets/naming.xml/LongVariable">
        <properties>
            <property name="maximum" value="32" />
        </properties>
    </rule>
    <rule ref="rulesets/design.xml/ExitExpression" />
    <rule ref="rulesets/design.xml/EvalExpression" />
    <rule ref="rulesets/design.xml/GotoStatement" />
    <rule ref="rulesets/design.xml/DepthOfInheritance" />
    <rule ref="rulesets/design.xml/CouplingBetweenObjects" />
    <rule ref="rulesets/design.xml/NumberOfChildren" />
    <rule ref="rulesets/unusedcode.xml" />
    <rule ref="rulesets/controversial.xml" />
</ruleset>

我为rulesets/naming.xml/ShortMethod添加了一个条目，所以现在看起来：

<?xml version="1.0" encoding="UTF-8" ?>
<ruleset name="Complex PHP Mess Detector Rule Set"
    xmlns="http://pmd.sf.net/ruleset/1.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://pmd.sf.net/ruleset/1.0.0 http://pmd.sf.net/ruleset_xml_schema.xsd"
    xsi:noNamespaceSchemaLocation="http://pmd.sf.net/ruleset_xml_schema.xsd">
    <rule ref="rulesets/naming.xml">
        <exclude name="LongVariable,ShortMethod" />
    </rule>
    <rule ref="rulesets/naming.xml/LongVariable">
        <properties>
            <property name="maximum" value="32" />
        </properties>
    </rule>
    <rule ref="rulesets/naming.xml/ShortMethod">
        <properties>
            <property name="minimum" value="3" />
            <property name="exceptions" value="ln" />
        </properties>
    </rule>
    <rule ref="rulesets/design.xml/ExitExpression" />
    <rule ref="rulesets/design.xml/EvalExpression" />
    <rule ref="rulesets/design.xml/GotoStatement" />
    <rule ref="rulesets/design.xml/DepthOfInheritance" />
    <rule ref="rulesets/design.xml/CouplingBetweenObjects" />
    <rule ref="rulesets/design.xml/NumberOfChildren" />
    <rule ref="rulesets/unusedcode.xml" />
    <rule ref="rulesets/controversial.xml" />
</ruleset>

但现在当我尝试运行它时，出现了以下错误：

Catchable fatal error: Argument 1 passed to PHPMD\RuleSetFactory::parsePropertiesNode() must implement interface PHPMD\Rule, null given,
called in phar://Utilities/PHP/phpmd.phar/src/main/php/PHPMD/RuleSetFactory.php on line 462
and defined in phar://Utilities/PHP/phpmd.phar/src/main/php/PHPMD/RuleSetFactory.php on line 489

phpmd是2.6.0版

最佳答案

我们还可以创建phpmd自定义规则集，而无需添加其他规则集

<?xml version="1.0"?>
<ruleset name="My first PHPMD rule set">

    <description>
       My custom rule set that checks my code...
    </description>
    <pmd version="@project.version@" timestamp="2017-09-29T20:00:17+00:00">
     <!-- Import the entire unused code rule set -->
         <rule ref="PHPMD/Rule/CyclomaticComplexity" />
         <rule ref="PHPMD/Rule/Design/NPathComplexity"/>
   </pmd>

无论您想设置什么规则，都可以在usr/share/phpmd/rule上找到，然后您可以在终端上启动命令

phpmd sourcefile.php xml codesize,phpmdruleset.xml
