java - 想法 : what is the difference between Build and Build Project?

Question

在 Intellij IDEA 中，在运行配置(应用程序类型，在 Java 项目中)中，您可以配置任务以在启动前执行。如下图所示，您可以选择“构建”和“构建项目”等。它们有什么区别？

阅读关于 compilation types 后在 IDEA 中，我知道这里的构建做了一个make，它编译自上次以来更改的类并链接它们。所以我猜测 Build Project 在整个项目的范围内这样做，但是我无法弄清楚 Build 在什么范围内运行。

来自 Intellij help > Run/Debug Configurations Dialog > Before Launch

Build: select to compile the specified module. The Build Module command will be executed. If an error occurs during compilation, IntelliJ IDEA won't attempt to start the run/debug configuration.

Build Project: select to compile the entire project. The Build Project command will be executed. If an error occurs during compilation, IntelliJ IDEA won't attempt to start the run/debug configuration.
