How to build jar file with gradle with dependencies
I'm building a jar file with Gradle. This jar file is being used as a library in another project. But when the project tries to use the jar file, a ClassNotFoundException is returned.
Caused by: java.lang.NoClassDefFoundError: com/auth0/jwt/JWT
I've included the jwt library in the gradle file building the jar:
compile group: 'com.auth0', name: 'java-jwt', version: '3.4.0'
The project using the jar can't seem to find this jar dependency in the jar.
I built the jar with the gradle command:
task fatJar(type: Jar) {
manifest {
attributes 'Implementation-Title': 'Jar File creation',
'Implementation-Version': version,
'Main-Class': 'com.group.me.name.MyJarClass'
}
baseName = project.name + '-all'
from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
with jar
exclude 'META-INF/*.RSA', 'META-INF/*.SF','META-INF/*.DSA'
}
How do I include the missing dependency in the jar?

You, generally, should not pack the dependencies inside a published JAR. It's better to declare them as dependencies in pom.xml and let the user of you JAR fetch them. It's just a good practice that should be enough.
If it's not enough, use Gradle Shadow:
plugins {
id 'com.github.johnrengelman.shadow' version '4.0.2'
}
Fat JAR is produced with shadowJar task in this case. Publishing is easy as well:
publishing {
publications {
shadow(MavenPublication) { publication ->
project.shadow.component(publication)
}
}
repositories {
maven {
url "http://your.repo"
}
}
}
