java - Maven 构建跳过清理和验证阶段

Question

我正在使用 IntelliJ IDE。我的项目是 maven 项目。令我困扰的是，例如，从 Maven 工具栏选择“安装”阶段并单击“运行 Maven 构建” ,

不执行clean阶段:

因此，正如您所看到的，第一步是 maven-resources-plugin:2.6:resources。据我了解maven docs就是当我们指定一个阶段时，所有先前的阶段都会执行到所选的阶段。每个 Maven 文档:

此命令在执行安装之前按顺序执行每个默认生命周期阶段(验证、编译、打包等)。您只需要调用要执行的最后一个构建阶段，在本例中为 install

为什么它跳过clean和validate阶段？

编辑:

我在运行配置部分也有clean阶段，但结果是相同的:

Answer 1

Maven 有 3 个不同的内置 lifecycles

There are three built-in build lifecycles: default, clean and site.

install 是默认生命周期的一部分，当您执行 install 时，没有理由执行 clean。

至于validate，它没有内置绑定(bind)，如您所见 here这意味着它不会 execute :

Furthermore, a build phase can also have zero or more goals bound to it. If a build phase has no goals bound to it, that build phase will not execute.
