Gradle Jar It hasn't found the main class

Hi @ggeliso,

I am not sure what the concrete problem is, but here are some pointers that should help you:

• Consider using the application instead of the plain java plugin. Then Gradle will do all the work of creating the manifest and packaging the application for you - https://docs.gradle.org/current/userguide/application_plugin.html
• If you absolutely need to do something manually, you should use configurations.runtimeClasspath instead of configurations.runtime (runtime is deprecated and might not always be complete).
