我想在我的父pom的pluginManagement中为插件定义不同的执行，然后将特定的执行绑定到子poms中的阶段。 我看到不一致的行为取决于使用的插件和pluginManagement部分的位置。
在第一个例子中，pluginManagement位于父pom中，为编译器插件定义了2个执行，为antrun插件定义了2个执行。

在子pom上运行'mvn clean install'将运行编译器插件的两次执行，并且只运行antrun插件的第一次执行，尽管只有第一次执行才绑定到一个阶段。
现在将pluginManagement移动到子pom：

这个pom提供了所需的行为，它只运行每个插件的第一次执行。 编译器插件（以及大多数其他插件）仅在pluginManagement位于同一个pom并且每个执行都绑定到phase = none的情况下才能正常工作（可能因为它将执行绑定到默认阶段）。 无论如何，antrun插件都能正常工作。
如何在父pom中使用pluginManagement部分并且不必在child poms中将不需要的执行绑定到phase = none时如何实现？ 这是Maven中的一个错误，还是这种行为在某种程度上是合理的？ 我在Maven 3.0.4和Maven 2.2.1上尝试过这个结果。
答案 0 :(得分：8)
提供的示例正常工作。在包含修复程序后，我没有重新部署父级。
大多数插件会将执行绑定到默认阶段。因此，当触发一个插件执行时，所有未绑定的执行都将绑定到默认阶段，并且也将运行。
为避免此行为，父pom的pluginManagement部分中插件的所有执行都应绑定到phase = none（如提供的示例中所示）。这样，除非在子poms中显式覆盖阶段，否则不会执行任何执行。
