Error: Application Server not specified - IntelliJ IDEA

Question

When I configure the Tomcat in the IntelliJ IDEA, there have a issue I don't understand.

Error: Application Server not specified

Before asking the question, I have searched the SO, found the related post: How to configure correctly the JBoss in the Intellij IDEA? I get Error:server instance not specified

But it is not fit me.

Attention

I did not Configure the Application Server, because I can not choose the hidden directory path.

Answer 1

On the top where it says:
Application server: [ text box ] configure

You need to specify the location of your local tomcat installation.

UPDATE

Per comments and updates, intelliJ somehow cannot locate tomcat installed under hidden folder.
Simply typing out the absolute path should work.

7. Click "+"
