How do I run the scala project?

My gradle build script:

    apply plugin: 'scala'
    repositories {
        mavenLocal()
        maven {
            url "http://maven.aliyun.com/nexus/content/groups/public/"
        }
        mavenCentral()
    }
    dependencies {
        compile group: 'org.scala-lang', name: 'scala-library', version: '2.13.1'
    }

You need to provide the classpath as well. Change run task declaration to:

task run(type: JavaExec, dependsOn: classes) {
   main = 'Demo'
   classpath = sourceSets.main.runtimeClasspath
}

And it will work fine. Demo .
