我想在父POM的插件管理中为插件定义不同的执行,并将特定的执行绑定到子POM中的阶段。
我发现插件的使用和插件管理部分的位置会导致不一致的行为。
在这个第一个例子中,插件管理位于父POM中,为编译器插件定义了2个执行和antrun插件的2个执行。

还有子POM:

在子模块上运行“mvn clean install”将运行编译器插件的两个执行和antrun插件的第一个执行,尽管每个插件的第一个执行都只绑定到了一个阶段。现在将插件管理移动到子模块:<?xml version="1.0" encoding="UTF-8"?>

这个 POM 文件提供了所需的行为,即只运行每个插件的第一个 execution。编译器插件(以及大多数其他插件)只在 pluginManagement 部分位于同一 POM 中,并且每个 execution 绑定到 phase=none 的情况下才能正常工作(可能是因为它将 executions 绑定到默认阶段)。antrun 插件在任何情况下都能正常工作。
如何在父 POM 中具有 pluginManagement 部分并且不必在子 POM 中特别绑定不需要的 executions 到 phase=none 的情况下实现此目标?这是 Maven 中的一个 bug 还是某种程度上合理的行为?我已经在 Maven 3.0.4 和 Maven 2.2.1 上尝试过,并获得了相同的结果。
execution-1
。你说编译器插件同时运行了execution-1
和execution-2
。但是,像我所说的那样,这并没有发生在我身上。 - maba
