maven-pmd-plugin 禁用一个模块

Question

我正在尝试为 maven 项目模块之一禁用 maven-pmd-plugin 的执行，但找不到有效的解决方案。
现在我在模块中有下一个:

    <properties>
      <cpd.skip>true</cpd.skip>
      <pmd.skip>true</pmd.skip>
      <maven.pmd.enable>false</maven.pmd.enable>
      <maven.pmd.cpd.enable>false</maven.pmd.cpd.enable>
    </properties>

并在调试输出中有下一个:

我想知道如果skip=true为什么会执行
据官方 FAQ我需要“简单地将 maven.pmd.enable=false 放入该子项目的项目属性中。”可能我没有正确地将它放入 pom.xml 中。它只是模块 pom 文件中的 吗？
-Dpmd.skip=true -Dcpd.skip=true 给出相同的结果

如果你想禁用一个 Maven 模块，你已经在那个模块中配置了 pmd。然后全部排除。
像这样:

			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-pmd-plugin</artifactId>
				<configuration>
					<analysisCache>true</analysisCache>
					<!-- enable incremental analysis -->
					<excludes>
						<exclude>**/**</exclude>
					</excludes>
				</configuration>
			</plugin>

Maven 多模块文档 ;hier
描述，子模块中的配置会覆盖顶级 pom 定义。
