How to setup CHelper and configure on IntelliJ?

Question

I tried for last two days. But I always draw a blank. I have trouble in setting up the project, and adding dependencies - and creating tasks - it always shows some error or the other.

I followed instructions from here Created a tusk and when I tried to run it, ended up with this exceptions

So I will appreciate if there is someone who is using it currently and give me a step by step full instruction form first to last, not only setup but also how to configure properly.

Answer 1

I have installed chelper and now its working properly. I am on ubuntu 16.04 and using intelliJ IDEA 16.2.2

Steps:

Select menu item File->Settings... , select Plugins in IDE Settings , push Browse repositories... button, right click on CHelper and select Download and Install (dont install the beta version). Click Yes , OK , Apply and Restart .

Right click on main toolbar, select Customize Menus and Toolbars... , select location where you want actions to be listed (probably end of Main Toolbar is good), click Add After... , select Plug-ins->CHelper and add actions you are interested in(probably all but Task )

After that open or create project that you want to use with plugin and click on Edit Project Settings from toolbar to set-up project directories.

This is the simplest project settings that works fine for me.

now for testing you can parse a contest or problem form Parse Contest from toolbar. parse a problem. you will find the problem(task) in you src/code folder and and after compiling the source will be create in test directory under project. and the name of the file will be Main.java , You can also copy source form the menu.
