• prettyjson -l response.json

• default behavior is to print pretty JSON which is indented and colorized.
• General Command prettyjson [-r] [-l] [-h] [-v] [-nc] <file>
• Options:
  • h: Show this help message.
  • v: Show version info.
  • r: Show raw Json file (as-is un-indented).
  • l: Print Line numbers in the output.
  • nc: Turn colorizing off.

• To create project Eclipse Project files, run gradle -b build9.gradle eclipse
• To create project Idea Project files, run gradle -b build9.gradle idea
• To build the project execute gradle -b build9.gradle
• To run the project execute gradle -b build9.gradle run

Once the project is created, you need to add the following to configure it for using Java9:

• Please refer to the link https://wiki.eclipse.org/Configure_Eclipse_for_Java_9
• Add the following lines in your eclipse.ini file. --add-modules=ALL-SYSTEM after the vm property. Refer to www.journaldev.com/10882/eclipse-ini-vm-arguments-file-location-mac-windows for setting it up.
• Start Eclipse
• Next, we need to add the dependent jars (in our case, JSON jar, JCDP and Commons CLI) on the module path. So, go to Project properties, then go to Java Build Path, and under Classpath, expand the twisty for each jar that you want to be a module. You should see a new entry called "Is not modular". Click on it and click the Edit button. Under the Modular properties dialog that opens, check the box "Defines one or more modules". Click OK and it should now say "Is modular" and it will be moved up to Modulepath.

• First delete the module-info.java present in the folder src/main/java
• To create project Eclipse Project files, run gradle eclipse
• To create project Idea Project files, run gradle idea
• To build the project execute gradle
• To run the project execute gradle run

• You can appropriately add the gradle plugins as per your choice of language in the build.gradle.
• Do not forget to delete ```java`` plugin found therein.

When you run this, it invokes, application main class, which just prints Json Viewer - Lets Begin Implementing!

Stories to be implemented are found on the Slideshare - Json Viewer

• JSON Java - We will be using Java JSON library. If you need a primer on how to use this library, please refer to a short tutorial on http://www.baeldung.com/java-org-json. It can parse JSON text, produce JSON from Map, List and Java Objects (bean style) and can pretty print JSON as well. If you are comfortable with any other Java JSON library, please feel free to use it, but make sure, you update the project dependencies in build.gradle
• Java Colored Debug Printer (JCDP) - has an easy syntax to print messages with a colored font/background on console (Win, MacOS and Linux based systems). Look here https://github.com/dialex/JCDP for the short primer and the documentation on ReadMe.md is quite sufficient for this project.
• Optionally (though not required) you may want to use Apache Commons command line parsing library - Commons CLI. Here is how you can use it https://commons.apache.org/proper/commons-cli/usage.html

• Make sure, all your tests run, before releasing your solution.
• It should not happen, that they run only on your machine ;)
• A batch file prettyjson.bat for Windows and prettyjson for Linux based platforms must be included. By default, the gradle build produces these scripts. This will call Java and pass command line args to it.
• NOTE: If you are using Java9, you need not do this, instead simply use JLink and produce a custom executable with the name prettyjson.
