In which dependcies the plugin in maven is placed

If you use MAVEN to manage your project, you'll find that you're relying on a lot of plugin, and that raises a question.

There may be two <dependcies> this tag in a project,

As follows

<dependcies>

A

</dependcies>

<build>

<dependcies>

B

</dependcies>

</build>

What is the difference between these two dependcies?

I found the answer on MAVEN's official web site:

Https://maven.apache.org/pom.html

On top I used a and B to represent two positions of dependcies,

Where A's role is to specify Who,what,where (what plug-in to do what)

The role of B is to specify when, how (configuration enable, and how the plug-in works, that is, the plug-in in build is to work with some other plug-in, or auxiliary build)
