Hi everyone,

I am trying to solve problems by JAVA so I want to use Chelper. Here is what I have done:

1. Install IntelliJ IDEA 2016.2.4

2. Install CHelper plugin

3. Create an empty project named "Competitive programming"

4. Change some project settings like the image below:

However, it does not work. When I click on "New task", it says "defaultDirectory should be under source and in non-default package."

Could anyone show me the way to setup CHelper? I am new to Java and IntelliJ so many things may be unclear with me.

Thank you very much for your help
