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，但找不到可行的解决方案。 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：

我想知道为什么如果skip = true它会执行 根据官方FAQ，我需要“简单地将maven.pmd.enable = false放入您的项目属性中，用于该子项目。”可能我没有正确地将它放入pom。它只是 在模块pom文件中？ -Dpmd.skip = true -Dcpd.skip = true给出相同的结果

Answer 1

如果要禁用maven模块，则在该模块中配置pmd。然后排除所有。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 multimodul文档;hier描述，子模块中的配置会覆盖顶级pom定义。

Answer 2

我找到了一个更好的解决方案，看看Disable a Maven plugin defined in a parent POM。

这样你就可以禁用插件，因此它根本不会运行模块，因此不会生成任何内容，因此这样构建时间也会减少。
