如何选择Maven插件？为何未配置maven-install-plugin仍可执行clean install

Hey there! Great question—this is a super common point of confusion for new Maven users, so let’s unpack it step by step:

• Maven has built-in default plugin bindings
  Maven’s core design includes pre-configured links between lifecycle phases and plugin goals. For standard phases like install, compile, or deploy, Maven already knows which plugin goals to trigger by default—you don’t need to explicitly list them in your pom.xml at all. The install phase is automatically tied to the maven-install-plugin:install goal out of the box.

• You only need to configure plugins to override defaults
  The reason your project has maven-clean-plugin configured is probably because someone wanted to customize its behavior—maybe adjusting the directories it cleans, using a specific plugin version, or adding extra parameters. Even if you didn’t configure it, Maven would still use the default version and settings for maven-clean-plugin:clean when you run mvn clean.

• Let’s walk through the lifecycle flow
  When you run mvn clean install, Maven first executes the clean lifecycle (using either your configured clean plugin or the default one), then runs through the full default lifecycle all the way to the install phase. Since install has a pre-built plugin binding, it automatically invokes maven-install-plugin without you needing to declare it in your project’s config.

To put it simply: Maven handles the heavy lifting of connecting standard plugins to lifecycle phases by default. You only need to add plugin configurations to your pom.xml when you want to change how a plugin behaves from its out-of-the-box setup.
