Is there a plugin like shadow for gradle 4.4 (fatJar) - gradle

Question

I am trying to make a fatJar and then move it. The shadow plug fails on me saying it cannot find the plugin. I am trying to create a fatjar.
I have this which moves the file just fine but it includes EVERY single jar file, I just want one big one and then move it:
task copyJarIntoDockerDirectory(type: Copy) {
dependsOn jar
from configurations.runtime
from jar
into '../docker/ekomi-import'
rename '(.*)-[0-9]+\\..*.jar', '$1.jar'
doFirst { println 'before copy' }
doLast { println 'after copy' }
}

You can use com.github.jengelman.gradle.plugins:shadow:2.0.2 plugin with Gradle 3.0+. Your minimal build.gradle file could look like this:
buildscript {
repositories {
jcenter()
maven {
url "https://plugins.gradle.org/m2/"
}
}
dependencies {
classpath "com.github.jengelman.gradle.plugins:shadow:2.0.2"
}
}
apply plugin: "com.github.johnrengelman.shadow"
task copyJarIntoDockerDirectory(type: Copy) {
dependsOn shadowJar
from 'build/libs/'
into 'docker/ekomi-import'
}
In my case final JAR is called products-service-all.jar. When I run:
gradle clean copyJarIntoDockerDirectory && tree docker
I get following output in bash console:
products-service [master●●●] % gradle clean copyJarIntoDockerDirectory && tree docker
BUILD SUCCESSFUL in 3s

└── ekomi-import
└── products-service-all.jar
1 directory, 1 file
Hope it helps.
