This is a great feature I was expecting as a developer. So exciting with sdkman. In the following example, I used Gradle version 3.4.1 to setup the multi-moudle project. Here the parent gradle.build file: task wrapper (type: Wrapper){ gradleVersion = '3.4.1' distributionType = Wrapper.DistributionType.ALL } subprojects{ apply plugin: 'java' dependencies { // https://mvnrepository.com/artifact/org.slf4j/slf4j-api compile group: 'org.slf4j', name: 'slf4j-api', version: '1.7.25' } repositories { mavenCentral() } jar { baseName = 'example1' version = '0.0.1-SNAPSHOT' } } As shown in the above, If you need to use wrapper (which

It is a best practice to separating common from varying in the Scala. Common parts are implemented as functions and the varying parts will be arguments: def createSeqOnCriteria(start:Int, end:Int, // createSeqOnCriteria: createSeqOnCriteria[](val start: Int,val end: Int,val criteria: Int => Boolean) => scala.collection.immutable.IndexedSeq[Int] criteria: Int => Boolean) = { // for (i <- start to end if criteria(i)) yield i // } //
