Main does not see other classes. What to add?

Question

Java

I ran into a problem while writing the program.

I created the Main class, set the actions I needed, created the Jsoner class, did everything the same way, vscode does not swear.


I ran the command: java -cp "$(printf %s: lib/*.jar)" ./src/don't care/Main.java
And got a response from java:
./src/don't care/Main.java:19: error: cannot find symbol
import whatever.Jsoner;
^
symbol: class Jsoner
location: package don't care ./src/don't care
/Main.java:27: error: cannot find symbol
Jsoner jsoner = new Jsoner();
^
symbol: class Jsoner
location: class Main
./src/don't care/Main.java:27: error: cannot find symbol
Jsoner jsoner = new Jsoner();
^
symbol: class Jsoner
location: class Main
3 errors
error: compilation failed

Contents Main:
import don't care.Jsoner;
public class Main {
public static void main(String[] string) {
Jsoner jsoner = new Jsoner();
jsoner.sendMsg();
}
}

Jsoner content:
public class Jsoner {
public static void sendMsg() {
System.out.println("ok");
}
}

truncated the extra code in Main intentionally, I think you are not particularly interested in the rest of the code, it should not cause this error.

Answer 1

It is very interesting how you are going to run the source code? They must first be compiled into classes with the javac command . In order not to compile everything manually, use the Gradle build system .

Answer 2

Good afternoon.
Well, first of all, why call a static method sendMsg()through an instance of the Jsoner class? You can access the method directly via Jsoner.sendMsg()
Second,
location: package неважно
Important. Since the package name must comply with the naming convention. I recommend opening this project in Intellij IDEA and most likely it will swear. It is possible that the directory name contains invalid characters (such as dashes or hyphens).
Thirdly,

java -cp "$(printf %s: lib/*.jar)" ./src/неважно/Main.java
