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

So I created an empty project, but when I create a new directory in the Project window, it does not show up. The directory is actually created, and if I navigate to the Project Files list I can see it there, but as far as I can tell there is no way to make even my src folder part of the actual project. This creates all kinds of problems when I have to move/refactor files, and I'm amazed that something so common and simple is so difficult.
You've created a folder, not a package. If ur using maven or grade, can I suggest u use them to generate an intelij project for you. The command escapes me but a quick Google should tell you
You can manually mark your directory as a sources root:
I'm working on a kotlin project that I want to execute as a jar. This is all done in IntelliJ Idea and I went about making the jar using the artifacts.
The process I followed was (as illustrated by an Idea guide):
Add artifact (as jar) from project structure
Build jar
Run jar
After this, I get a
'no main manifest attribute, in ____.jar'
What I have tried after reading several stack overflow questions:
Checking that the manifest file is in the correct folder and has the correct path in the artifact
Adding code to the build.gradle file for the jar->manifest portion
Trying the method of moving the manifest stuff into a resources folder
Checking that the jar exists
Moving the manifest stuff into a different folder (java,kotlin,out folders)
Making sure that the manifest file is in the correct format
All of the above has not worked.
Something that is confusing to me is that, even when I alter the manifest file to be in "incorrect" format, it still gives the same error. The path stated in the artifact's details is correct yet there is no difference even when I purposely input incorrect items in the manifest file. Not sure if that is the"real" problem but I'm also not sure how to fix that as well
None of the solutions worked for me.
I solved it in this way:
When setting up the artifact, change:
Meta-inf: (...)\src\main\ (you must remove "java")
Also, there was a problem with resources, solved this way:
When setting up the artifact:
Output Layout > Add copy of > Directory content > resources.
That's all!
For anyone that may have encountered this problem in intellij and did not find a solution in any other posts, what helped me was
Navigating to Project Structure
Going to the Artifacts tab
Explicitly adding a new META-INF/ directory in my jar
Adding the created MANIFEST.MF file to the META-INF/ in the jar FROM THE ARTIFACTS TAB
Rearranging the order for the META-INF/ to be at the top
Building and running
The end result looked like this
while creating the exeutable jar file explicitly create a mainfest.txt file
that should be in order of the directory structure and mainfest.txt file should contain only one line (Main-Class:name of the class containg main method)then run the jar tool
When starting SBT I see
Loading project definition from /Users/shruti/.sbt/0.13/staging/0156a9e3df5385400375/xyz/project
which is not where my project is located. (I wouldn't care, but the changes I make are not being reflected in this copy.) I searched my entire project but this path is not defined or written anywhere, neither in scalaopts. A grep over all files doesn't work either.
Does anybody know where this path is defined or how to change it?
Thanks!
sbt uses the staging area when the folder containing the project is not read/write. Making the project folder read/write should fix this.
Is there a way to set a default path when opening a project?
(File -> Open) . It's always pointing out to X:\Users\\Username.
I've been googling and looking inside X:\Users\Username\.IdeaIC15\config\options for configuration file which could be the case, but found nothing so far. Anyone know where i can change it?
I searched for a solution, but there is no easy one in IDEA/Webstorm UI.
You have to edit the webstorm64.vmoptions/ idea64.vmoptions file (or webstorm.vmoptions/ idea.vmoptions if you are on a 32bit system).
Add the line
-Duser.home=YOUR_NEW_DEFAULT_PATH
The IDE settings folder (e.g. .WebStorm11) must be either copied to your new path or imported on first start of IntelliJ/WebStorm.
I checked quite a few similar questions, but so far I am unsatisfied with the solutions.
Ever use the Minecraft Server? At initial launch, it creates all the files and folders it needs, and allows you to make changes to files like Server.properties and ops.txt by making them external of the executable jar file.
I'm working on a similar project, and I want to duplicate that behavior. Everything works great when I run it in eclipse. When I export to a jar file though, things get funky. The external files and folders are created without a hitch, but afterword, it would appear as though they cannot be read from or written to. Any ideas how Notch made his server?
--edit--
Scratch that, it doesn't even appear to reliably create the files and folders. Maybe it only creates them the very first run after creation?
--edit again--
It creates them in the root directory. When I tested it in eclipse, the root directory was limited to the folder containing the project, and therefore looked fine. The solution was to make the class aware of it's location, and include it in all file operations.
Have the main class in your executable jar file look up where it is, then have it store that information in a global String or something. Prefix your filenames with that string in your file operations, and voila! It's writing to the correct directory.
