请，我需要一些关于以下错误的帮助

我正在一个Maven项目中设置PMD插件，但是返回了一些我无法确定原因的错误

我当前正在使用以下设置：

  • 月食火星4.5.1
  • Maven 3.3.3
  • maven pmd插件3.5

我通过在工作区根目录下名为ruleset.xml的文件中设置规则来定义PMD规则

<?xml version="1.0" encoding="UTF-8"?>
<ruleset xmlns="http://pmd.sourceforge.net/ruleset/2.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="pmd-eclipse"
    xsi:schemaLocation="http://pmd.sourceforge.net/ruleset/2.0.0 http://pmd.sourceforge.net/ruleset_2_0_0.xsd">

    <description>PMD Plugin preferences rule set</description>

    <rule ref="rulesets/plsql/codesize.xml/NPathComplexity" />
    <rule ref="rulesets/plsql/codesize.xml/ExcessiveMethodLength" />
    <rule ref="rulesets/plsql/codesize.xml/ExcessiveParameterList" />
    <rule ref="rulesets/plsql/codesize.xml/ExcessiveObjectLength" />
    <rule ref="rulesets/plsql/codesize.xml/ExcessiveTypeLength" />
    <rule ref="rulesets/plsql/codesize.xml/ExcessivePackageBodyLength" />
    <rule ref="rulesets/plsql/codesize.xml/ExcessivePackageSpecificationLength" />
    <rule ref="rulesets/plsql/codesize.xml/CyclomaticComplexity" />
    <rule ref="rulesets/plsql/codesize.xml/TooManyFields" />
    <rule ref="rulesets/plsql/codesize.xml/NcssMethodCount" />
    <rule ref="rulesets/plsql/codesize.xml/NcssObjectCount" />
    <rule ref="rulesets/plsql/codesize.xml/TooManyMethods" />
    ...
</ruleset>

一旦我在pom.xml文件中配置了PMD插件

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-pmd-plugin</artifactId>
    <version>3.5</version>
    <configuration>
        <linkXRef>true</linkXRef>
        <verbose>true</verbose>
        <failOnViolation>false</failOnViolation>
        <rulesets>
            <ruleset>ruleset.xml</ruleset>
        </rulesets>
    </configuration>
    <executions>
        <execution>
            <goals>
                <goal>pmd</goal>
            </goals>
            <phase>package</phase>
        </execution>
    </executions>
</plugin>

当我运行pmd:pmd
我得到以下错误：

  • net.sourceforge.pmd.RuleSetNotFoundException: Can't find resource 'rulesets/plsql/codesize.xml' for rule 'NPathComplexity'. Make sure the resource is a valid file or URL and is on the CLASSPATH.

即使添加plexus-classworlds依赖项，它仍然失败

    通过增加这种依赖性，可以解决这个问题：

    <dependency>
    <groupId>net.sourceforge.pmd</groupId>
    <artifactId>pmd-plsql</artifactId>
    <version>5.4.1</version>
</dependency>
