Maven构建可以清除并验证阶段

Question

我正在使用IntelliJ IDE.我的项目是maven project.困扰我的是,例如从Maven Toolbar中选择"Install"阶段并单击"Run Maven Build",

在clean不执行相:

所以,正如你所看到的那样,第一步是maven-resources-plugin:2.6:resources.从我对maven文档的理解是,当我们指定一个阶段时,所有先前阶段都会执行到所选阶段.每个maven doc:

This command executes each default life cycle phase in order (validate, compile, package, etc.), before executing install. You only need to call the last build phase to be executed, in this case, install

为什么要跳过clean和validate阶段？

编辑:

我也有该部分的clean阶段Run Configuration,但结果是相同的:

Answer 1

Maven有3种不同的内置生命周期

有三个内置的构建生命周期:默认,清理和站点.

install是默认生命周期的一部分,没有理由clean在执行时执行install.

至于validate它没有内置绑定,你可以在这里看到,这意味着它不会执行:

此外,构建阶段也可以具有零个或多个绑定目标.如果构建阶段没有绑定目标,则不会执行该构建阶段.
