无法为规则'NPathComplexity'找到资源'rulesets / plsql / codesize.xml'

标签： java eclipse maven pmd

请为以下错误提供一些帮助。

我正在 Maven项目中设置 PMD插件，但是会返回一些我无法确定原因的错误。

我目前正在使用以下设置：

  • Eclipse Mars 4.5.1
  • Maven 3.3.3
  • maven-pmd-plugin 3.5

我通过在工作区根目录中名为ruleset.xml的文件中设置规则来定义我的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>

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>

当我跑pmd:pmd时 我收到以下错误：

即使添加plexus-classworlds依赖，它仍然会失败。

1 个答案:

答案 0 :(得分：1)

通过添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>

在<build>

中的插件上 
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-pmd-plugin</artifactId>
    <version>3.5</version>
    <dependencies>
        <dependency>
            <groupId>net.sourceforge.pmd</groupId>
            <artifactId>pmd-plsql</artifactId>
            <version>5.4.1</version>
        </dependency>
    </dependencies>
    <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>
