Installing OpenJDK 11 on macOS (again)

I have started to use SDKMan to simplify my life with installing and updating many software that I use regurlarly. Java is one of them. It is the simplest thing to install java with sdk man:

sdk i java 11.0.8.hs-adpt

As simple as that.

I can just use Java 11 from that point on. You can also install Java 8 and switch between both. Convenient when you have to maintain older software.

If I want to update to a new release, I simply have to type:

sdk ug java

Can it really get any easier?

I use the SDKMan on my linux laptop as well and it easily works on both.

I also manage gradle, spring-boot and spark with SDKMan so most of my coding tools are kept up to date with the same tool.

Learning Kotlin by building

It took longer than I want to admit to have a simple Koltin application build this morning. The build.gradle.kts needed a bit of tweaking to get a simple 3 class application with a single test to properly build.

Here is the content of the build.gradle.kts:

import org.jetbrains.kotlin.gradle.tasks.KotlinCompile

plugins {
kotlin("jvm") version "1.4.10"
}
dependencies {
implementation(kotlin("stdlib"))
implementation("org.jetbrains.kotlin:kotlin-test:1.4.10")
testImplementation("org.junit.jupiter:junit-jupiter-api:5.6.2")
testImplementation("org.assertj:assertj-core:3.17.2")
testRuntimeOnly("org.junit.jupiter:junit-jupiter-engine:5.6.2")
}
repositories {
mavenCentral()
}
val compileKotlin: KotlinCompile by tasks
compileKotlin.kotlinOptions {
jvmTarget = "11"
}
val compileTestKotlin: KotlinCompile by tasks
compileTestKotlin.kotlinOptions {
jvmTarget = "11"
}
