Why does javac throw compile errors when my IDE does not?

Question

I'm using IntelliJ for java development. I want to run my application on another host which I only have shell access to.

When I run my application locally, it's all fine and dandy. When I attempt to compile the code on the remote host, I get:

usr@host1:~/mp1/src$ javac -cp ../ Control.java
Control.java:10: error: cannot find symbol
    private static Node genNode = null;
                   ^
  symbol:   class Node
  location: class Control
Control.java:25: error: cannot find symbol
            genNode = new Node(hostname);
                          ^
  symbol:   class Node
  location: class Control
2 errors

The file Node.java is in the same directory:

mp1
├── src
│   ├── ClientControl.java
│   ├── Control.java
│   ├── Node.java
│   ├── Registrar.java
│   ├── ServerControl.java
│   ├── UX.java
├── lib
│   └── kryonet-2.21-all.jar

I can't compile locally either, unless it's from within the IDE, so I assume I'm just not doing something right. What am I missing? I just want to be able to run my application from a shell, I don't really care how.

You have to correctly set the classpath when you compile.

There is a problem in your classpath. Since you have set only the parent directory as your classpath. You have to include src too, since it contains your other source files.

Try:

javac  -cp .:../lib/kryonet-2.21-all.jar Control.java
