Here is a version that does not use a plugin, more like the Groovy version.
import org.gradle.jvm.tasks.Jar
val fatJar = task("fatJar", type = Jar::class) {
baseName = "${project.name}-fat"
manifest {
attributes["Implementation-Title"] = "Gradle Jar File Example"
attributes["Implementation-Version"] = version
attributes["Main-Class"] = "com.mkyong.DateUtils"
}
from(configurations.runtime.map({ if (it.isDirectory) it else zipTree(it) }))
with(tasks["jar"] as CopySpec)
}
tasks {
"build" {
dependsOn(fatJar)
}
}
Some commenters pointed out that this does not work anymore with newer Gradle versions.
Update tested with Gradle 5.4.1:
import org.gradle.jvm.tasks.Jar
val fatJar = task("fatJar", type = Jar::class) {
baseName = "${project.name}-fat"
manifest {
attributes["Implementation-Title"] = "Gradle Jar File Example"
attributes["Implementation-Version"] = version
attributes["Main-Class"] = "com.mkyong.DateUtils"
}
from(configurations.runtimeClasspath.get().map({ if (it.isDirectory) it else zipTree(it) }))
with(tasks.jar.get() as CopySpec)
}
tasks {
"build" {
dependsOn(fatJar)
}
}
Note the difference in configurations.runtimeClasspath.get()
and with(tasks.jar.get() as CopySpec)
.
