Once I provided some gradle scripts for building a runnable jar here, and now I tried to change them to gradle script kotlin and the following are the different versions of themCustom build(Building a runnable jar by the way "Copy required libraries into a sub-folder next to the generated Jar" in eclipse)
//Builing a runnable jar by the way "Copy required libraries into a sub-folder next to the generated Jar"
import org.gradle.jvm.tasks.Jar
plugins {
java
eclipse
}
//profile configuration
configure<JavaPluginConvention> {
setSourceCompatibility(1.7)
setTargetCompatibility(1.7)
if(project.hasProperty("env")){
var env = project.property("env");
sourceSets.getByName("main").resources.srcDirs("src/main/profile/" + env)
}
}
dependencies {
compile("junit:junit:4.12")
}
repositories {
jcenter()
}
//copy dependencies jars to a folder
val copyDependencies = task<Copy>("copyDependencies") {
from(configurations.compile)
into("libs/lib")
}
//the jar tasks for building a runnable jar,
//and the denpendcies jars are in a folder next to the generated jar
val jar: Jar by tasks
jar.apply {
dependsOn(copyDependencies)
manifest.attributes.apply {
put("Main-Class", "samples.HelloWorld")
if (!configurations.runtime.isEmpty()) {
put("Class-Path
","./ lib/" + configurations.runtime.map{ it.name }.joinToString(" lib/"))
}
}
} The following are differents ways of building runnable jar with spring boot gradle plugin and kotlin-dsl, and most of them I make the change according to the internet resources on stackoverflow and github.
