在阶段定义插件目标答案

【问题标题】：Defining plugin goal at phase在阶段定义插件目标
【发布时间】：2021-12-25 20:08:17
【问题描述】：

我正在尝试定义一个插件目标，以便它可以在特定阶段自动执行；比如说测试阶段。但我无法做到这一点。例如，我编写了以下 pom.xml。请注意，在我的 XML 元素中，我有一个子元素，它是“test”。我可以使用命令“mvn antrun:run@ant-echo”执行我的目标；但是“mvn test”并没有执行那个目标。我使用的是 Maven 版本 3.8.3，我的 JDK 版本是 16。

【问题讨论】：

您必须将 antrun 插件包括执行块移出 pluginManagement...
谢谢@khmarbaise。那行得通。

为了让您的插件在配置的生命周期阶段执行，您必须在 <plugin> 部分中指定插件目标绑定和配置：
