Running a Java program created in IntelliJ on Windows Command Line

Question

I have seen many people ask this question but none of the answers have solved my problem.

I have written a Java project in Intellij which runs fine in Intellij. I need it to run on the command line however.

Intellij automatically builds the .class files in the following directories which is outlined as follows:

C:\git\myProject\out\production\myProject\main
C:\git\myProject\out\production\myProject\openNlpTools
C:\git\myProject\out\production\myProject\sentimentAnalysisTools

I have three sub directories here. The file with the main method is in the \main folder.

To run the program I thought I used the following:

java main.FileMonitor

When I run this however I get the following error:

Error: Could not find or load main class main.FileMonitor

Does anyone have any tips as to why this isn't running? Intellij runs the program fine, is there anyway I can see the command IntelliJ uses to run the program?

Thanks!

What is the command You are using, and in what directory do You launch it?. Why don't You just export jar file and run it? — maslan
I am using the command: "java main.FileMonitor" to try run my program. I don't mind which directory I launch it in. — illwalkwithyou

If you can't file a class it usually means you didn't include it in your class path. Some ways to run in the command line

Copy from IntelliJ

Run the program in InetlliJ.
Copy the first line as this will contain full command line
Edit the command line to remove bits you don't need.

Using Maven/Gradle

Set the Main-Class in the assembly plugin
build the program with assembly:single
this will create a Jar you can run on the command line.
