Intellij Idea problem with text file impossible to read

Question

I have a problem using Intellij Idea.

I am absolutely unable to load text file as InputStream - it doesnt matter where do I put the file (main/java, main/resources...) it just can't find the file - in Eclipse everything works just fine.

I tried setings->compiler->resource patterns and added ?*.txt but that doesn't seem to work either.

Any help is appreciated.

new File("file.txt") or new File("/file.txt") - if they are in source roots. — Jarek, Aug 18 '11 at 12:01

If you load it as a File, make sure that Working Directory is properly set in IDEA Run/Debug Configuration, since it's the default directory where Java will look for a file when you try to access it like new File("file.txt"). Working directory should be set to the directory of your project containing .txt files.

If you load files as a classpath resource, then they should reside somewhere under Source root and will be copied to the classpath according to Settings | Compiler | Resource Patterns.

If you can't get it working, upload your project somewhere including IDEA project files so that we can point to your mistake.

For my multi-module project I needed to set it to $MODULE_DIR$ — Dan Alvizu, Feb 19 '15 at 17:46

Look at the image, notice that the txt files are in the project root, and not the source folders (in blue).

If this doesn't work, it means the directories upon the project/module creation, were screwed! – Paschalis Feb 26 '14 at 19:49

An easy way to figure out the same would be to try creating a file in the same fashion and see where it gets created in your project. You can put your input file at the same location and it should work just fine (if it doesn't, you should check your resource pattern which might be causing the file to be not copied over in the build output).

This method actually gives you the working directory of your intellij settings which is pointed out in the accepted answer. Just sharing as I had similar trouble and I figured out this way. :)

If you open the Project Structure dialog, and click on Modules and select your module - are the correct folders marked as Source Folders on the sources tab?

Also, if you print out the absolute path of that file you are trying to read, is that anywhere near where you expect it to be?
