Please support gradle plugin for [email protected]

[vpa1977]

What needs to get done

Add gradle plugin that will allow build gradle projects that are de-facto standard for modern Java.
Gradle contains breaking changes between major versions so the plugin should try to use gradle wrapper if present.
When the gradle wrapper is not present it should expect the user to install gradle in the build image manually.

Why it needs to get done

Gradle is a de-facto standard for the modern Java projects.
Is it required as a part of wider goal of supporting Spring Boot.
