Building Scala projects

Following the last section, most of this section would be very predictable from the application build's standpoint. So let's quickly go through the gist of it. The directory structure is as follows:

qotd-scala
├── build.gradle
└── src
    ├── main
    │   ├── java
    │   │   └── com/packtpub/ge/qotd
    │   │                       └── QotdService.java
    │   └── scala
    │       └── com/packtpub/ge/qotd
    │                           └── ScalaQotdService.scala
    └── test
        └── scala
            └── com/packtpub/ge/qotd
                                └── ScalaQotdServiceTest.scala

All Scala source files are read from src/main/scala and src/test/scala, unless configured using sourceSets. This time, the only plugin that we need to apply is the scala plugin, which just like the groovy plugin, implicitly applies the java plugin to our project. Let's write the build.gradle file for this project:

apply plugin: 'scala'

repositories {
  mavenCentral()
}

dependencies...
