Quickly Create a Scala Project Using Gradle in Intellij IDEA

Easy Way¶

1. Create a directory (e.g., demo_proj) for your project.

2. Run gradle init --type scala-library in terminal in the above directory.

3. Import the directory as a Gradle project in IntelliJ IDEA. Alternatively, you can add apply plugin: 'idea' into build.gradle and then run the command ./gradlew openIdea to import the directory as a Gradle project in Intellij IDEA.

Hard Way¶

1. Create a Gradle project in IntelliJ IDEA.

2. Create a directory named scala under src/main.

3. Mark the directory src/main/scala as source root directory.

4. Open build.gradle and change its content to the following.

    plugins {
        id 'scala'
    }
    apply plugin: 'idea'
   
    group 'net.legendu'
    version '1.0-SNAPSHOT'
   
    sourceCompatibility = 1.8
   
    dependencies {
        // Use Scala 2.12 in our library project
        implementation 'org.scala-lang:scala-library:2.12.7'
   
        // Use Scalatest for testing our library
        testImplementation 'junit:junit:4.12'
        testImplementation 'org.scalatest:scalatest_2.12:3.0.5'
   
        // Need scala-xml at test runtime
        testRuntimeOnly 'org.scala-lang.modules:scala-xml_2.12:1.1.1'
    }
