Java

IntelliJ Compiler/Executor is broken, and I get the same Error: Cannot find or load main class Main.

IntelliJ IDE has been said to be one of the most useful and user-friendly Development Software Applications for Java. It ain't working out too well right now...

I'm trying to create a simple "Hello World" project just to see how this keeps happening, but regardless of what I do, I get the same error every time.

Error: Could not find or load main class sample.Main I've been researching for a fix for this for days and hours today, and I'm VERY mad that I can't find anything on how to fix it. I've already tried reinstalling the JDK and IntelliJ, and I'm not using any external software. I simply want to make a program and test it using IntelliJ's VM, but it keeps throwing the same error every time. I've tried remaking the Manifest file, exporting it to a JAR works perfectly and I am able to run the JAR file, I am able to compile the project externally using my local Terminal, but IntelliJ refuses to be cooperative. Please help me fix this; it's VERY frustrating.

Hi Nick

I fully understand you, I also had a lot of problems with IntelliJ in the beginning an used the BlueJ IDE for a quite long time. But as soon as it's running its super awesome.

Have you already selected the main class?

I have referenced the main class in multiple occasions. Like I said above, creating a JAR file runs completely fine, and compiling using my local Terminal does the same. I've edited run configurations and set the path to the Main class, and have even created a manifest that does the same. Unfortunately, none of these methods are working in my liking, or at all.
