How to solve java file mapped to not java file type text

Question

I wanted to add a java class to a project, but I did a mistake and added it as a text file. Then, I removed it and tried to add it again as a java class, but unfortunately it doesn't work anymore. And I get the following error:

Unable to parse template "Class" Error message: ABC.java mapped to not java file type text

As I searched, I faced some solutions like this one but I can't find File Type under Editor or anything similar that I can change as suggested in the solution.

Any help would be appreciated.

PS: I am using IntelliJ 2018.3.4.

Thanks in advance,

Answer 1

Go on File->Settings and a dialog will open. In that dialog navigate on the left part to Editor/File Types and then you need to choose from the section Recognized File Types Java Class and remove from bottom section the problematic extension (note you have a small minus button on the right)

Answer 2

Select required file type in top list (Recognized File Types) -- do it for "Text files" In bottom list (Registered Patterns) select undesired pattern -- "SomeFileName.java" Click on "-" (Minus) button to remove pattern from the list Repeat 1-2-3 for other undesired patterns

If desired, you can also do this manually by editing config file while IDE is closed. Because it's IDE-wide setting, it is not stored in .idea folder (which has project settinsg only) -- the file to look for is called filetypes.xml and shoudl be located in ~/Library/Preferences/IntelliJIdeaXX/options ( see http://devnet.jetbrains.net/docs/DOC-181 for other OS etc )

Answer 3

This is a variant of Markov's answer that worked in my scenario.

Try going to File->Settings->Editor->File Type and to the Recognized File Types tab. Click the "Auto-detect file type by content" choice, and delete the name of the file you are trying to create from the "File Name Patterns" section by using the minus button.
