Java still used for many digital product companies even today. Currently, Java is on version 13. Today I want to show how to use JDK13 with Gradle6 . JDK13 has some improvements on GC(as usual), minor new methods for Strings and IO and there are 2 interesting new Experimental Features. So let's get started.

Gradle right now is the standard tool for Java builds. Before gradle, pretty much everybody was using maven . Working with cloud computing very often we need do remote debugging. In this blog post, I will show how to configure remote debugging for all your gradle projects.  The nice thing about the approach I will show is that you don't need to change your build.gradle files since we will do it as a global config this will be valid for all. We also will setup configs for Eclipse and IntelliJ IDE support in the same file. Since we will configure remote debug you need to keep in mind that debug port need to be open in all security groups and firewalls in order to work.  Keep in mind remote debug is slow especially with Amazon. We will open port 9009, but you can change the port if you like. This config works with Jetty and also with Java main classes as well.

Gradle Dynamic Resolution strategy a.k.a use a + on the dependency is a usable feature.  This is handy because you can do something like spring:spring-core:4.0.+ and gradle will always get the latest snapshop for you -  but them to make this work fine you need people have discipline to do proper major/minor versioning. 

On the previous posts i show how to use docker , docker-compose and nodejs with vagrant now let`s do a full jvm env :-) This setup is pretty easy and straightforward for you however it could take some time depending of your internet bandwidth because we gonna download several components. Remember you need to have Vagrant installed already, this time we gonna need more than just the Vagrant file because java, scala, clojure for instance require we setup environment variables so we gonna need change some files for clojure and sbt  in order to make everything work smoothly.
