Maven and Gradle

What a session covers

The tutor works through these with you, in conversation and code. A session ends when you have shown them, not when a video does.

1. Explain what the build tool does from dependencies to packaging
2. Add a dependency and run the tests through the wrapper
3. Spot the build run with a global install instead of the wrapper

In practice

A few lines that show Maven and Gradle doing its job.

<dependencies>
  <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
  </dependency>
  <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
  </dependency>
</dependencies>
<!-- ./mvnw verify  -> compiles, tests, packages target/app.jar -->

The common mistake

How it stays learned

Once a session shows you understand Maven and Gradle, it comes back for review. Each review takes a minute and tells the memory model how well you still know it.

1. Day 3First recall, while it is fresh
2. Day 7Second, a week on
3. Day 18Last, when it has settled
