Micronaut - shadow fat-jar plugin not working with corporate repo

Question

I am using Micronaut framework for a project and Micronaut CLI generates project with com.github.johnrengelman.shadow gradle plugin which works fine when I run the jar using-

$ java -Dmicronaut.environments=E1 -jar build/appBundle/app.jar

build.gradle-

plugins {
  id "com.github.johnrengelman.shadow" version "5.0.0"
}

...

shadowJar {
    mergeServiceFiles()
}

The issue is that com.github.johnrengelman.shadow plugin is not working with Jenkins for some reason and I am suspecting that it's not available in our corporate repo(and can't be added). While I am able to create an executable fat-jar using jar task of java plugin, it fails with following error-

$ java -Dmicronaut.environments=E1 -jar build/appBundle/app.jar
16:12:22.662 [main] INFO  i.m.context.env.DefaultEnvironment - Established active environments: [E1]
16:12:22.863 [main] INFO  io.micronaut.runtime.Micronaut - No embedded container found. Running as CLI application

build.gradle-

plugins {
  id "java"
}

...

jar {
  manifest {
    attributes "Main-Class": "axp.payments.pci.dss.PaymentsPciDssDispatcher"
  }

  from {
    configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
    configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
  }
}

Primary ask is why wouldn't com.github.johnrengelman.shadow plugin work with a corporate repository?

Answer 1

Solved

The issue was that plugin{...} block doesn't access private/corporate repo.

Solved it by reverting plugin definition from plugins{...} to older way of definition which is apply plugin...

Added older way of applying plugin (which is the only way to make it work with private repo)-

apply plugin: "com.github.johnrengelman.shadow"

Removed (doesn't access private/corporate repo)-

plugins {
  id "com.github.johnrengelman.shadow"
}
