maven - 无法在 maven-pmd-plugin 5.0.2 中使用自定义规则集

Question

我希望 maven-pmd-plugin 包含我指定的规则集并排除一些规则(特别是 UselessParentheses)

就像 documentation 中描述的一样，我将以下内容放在所有模块的父级 pmd.xml 中:

  <reporting>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-pmd-plugin</artifactId>
        <version>3.0</version>
        <configuration>
          <rulesets>
            <ruleset>/home/ubuntu/ruleset.xml</ruleset>
          </rulesets>
        </configuration>
      </plugin>
    </plugins>
  </reporting>

并准备了一个这样的自定义规则集:

  <!-- We'll use the entire rulesets -->
  <rule ref="rulesets/java/basic.xml"/>
  <rule ref="rulesets/java/imports.xml"/>
  <rule ref="rulesets/java/codesize.xml"/>
  <rule ref="rulesets/java/design.xml"/>
  <rule ref="rulesets/java/strings.xml"/>
  <rule ref="rulesets/java/unusedcode.xml"/>

  <!-- We want everything from this except some -->
  <rule ref="rulesets/java/unnecessary.xml">
    <exclude name="UselessParentheses"/>
  </rule>

作为主要部分。

然而，当我运行 mvn clean jxr:jxr pmd:check我在报告中有“无用括号”。此外，使用 -X 运行它节目

[DEBUG] Preparing ruleset: java-basic
[DEBUG] Before: java-basic After: java-basic.xml
[DEBUG] The resource 'rulesets/java/basic.xml' was found as jar:file:/home/ubuntu/.m2/repository/net/sourceforge/pmd/pmd/5.0.2/pmd-5.0.2.jar!/rulesets/java/basic.xml.
[DEBUG] Preparing ruleset: java-unusedcode
[DEBUG] Before: java-unusedcode After: java-unusedcode.xml
[DEBUG] The resource 'rulesets/java/unusedcode.xml' was found as jar:file:/home/ubuntu/.m2/repository/net/sourceforge/pmd/pmd/5.0.2/pmd-5.0.2.jar!/rulesets/java/unusedcode.xml.
[DEBUG] Preparing ruleset: java-imports
[DEBUG] Before: java-imports After: java-imports.xml
[DEBUG] The resource 'rulesets/java/imports.xml' was found as jar:file:/home/ubuntu/.m2/repository/net/sourceforge/pmd/pmd/5.0.2/pmd-5.0.2.jar!/rulesets/java/imports.xml.

所以看起来 pmd 忽略了我的自定义规则集。

我希望自定义规则集起作用。我究竟做错了什么？

您已配置 maven-pmd-插件 作为 reporting这是

Reporting contains the elements that correspond specifically for the site generation phase. Certain Maven plugins can generate reports defined and configured under the reporting element.

这意味着您应该使用以下命令执行:-

mvn clean site

如果您想执行您提到的，请将您的配置复制到 builds ，例如

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-pmd-plugin</artifactId>
            <version>3.0</version>
            <configuration>
                <rulesets>
                    <ruleset>/home/ubuntu/ruleset.xml</ruleset>
                </rulesets>
            </configuration>
        </plugin>
    </plugins>
</build>

然后当你执行

mvn clean jxr:jxr pmd:check

结果应该如你所料。您可以进一步了解 Maven Pom， here .

我希望这可能会有所帮助。

问候，
