Description

Environment
  • Operating System: windows 11
  • JDK version: "17.0.7" 2023-04-18 LTS
  • Visual Studio Code version: 1.84.0 user setup
  • Java extension version: v.0.25.15

When I create the following code I get a compilation error saying that certain packages do not exist. The steps I followed are:

1. create a project in java in my case it is called OCP JAVA 17

2. create a folder called 12. Modules (within this folder is the directory with program codes and modules written in Java 17)

3. create a folder called feeding

4. inside the feeding folder, create a module-info.java file with the following code
module zoo.animal.feeding {
    exports zoo.animal.feeding;
}
5. inside the feeding folder, create a package or folders in the following order zoo/animal/feeding and add the Task.java file with the following code
package zoo.animal.feeding;

public class Task {
    public static void main(String... args) {
        System.out.println("All fed!");
    }
}
6. compile Task.java class and module-info.java with following command in terminal opening from 12.Modules folder
   javac -p
   mods -d
   feeding
   feeding/zoo/animal/feeding/Task.java feeding/*.java

7. create a folder called mods and run the following command in the terminal to package our compiled code from the 12.Modules folder
   jar -cvf
   mods/zoo.animal.feeding.jar -C
   feeding/ .

8. run the program by entering the following command in the terminal from 12.Modules
   java -p
   mods
   -m
   zoo.animal.feeding/zoo.animal.feeding.Task
   must be printed in console All fed!

9. create a folder called care with the following file module-info.java with the code
module zoo.animal.care {
    exports zoo.animal.care.medical; //here is vsc supposed compilation error

    requires zoo.animal.feeding;
}
10. inside the care folder create 2 packages/folders in the following order zoo/animal/care/details and zoo/animal/care/medical

11. in the zoo/animal/care/details package add the following file HippoBirthday.java
// HippoBirthday.java
package zoo.animal.care.details;

import zoo.animal.feeding.*;

public class HippoBirthday {
    private Task task;
    public static void main(String... args) { //mio
        System.out.println("Feliz cumple"); //mio
    }
}
12. in the zoo/animal/care/medical package add the following Diet.java file
// Diet.java
package zoo.animal.care.medical;

public class Diet {
    public static void main(String... args) { //mio
        System.out.println("Diet"); //mio
    }
}
13. compile and package what is inside the care folder, in the terminal from 12.Modules with the following command
    javac -p
    mods
    -d
    care
    care/zoo/animal/care/details/_.java
    care/zoo/animal/care/medical/_.java
    care/module-info.
    java

jar -cvf mods/zoo.animal.care.jar -C care/ . 14) run the classes that are inside the zoo.animal.care.medical package (which vsc says does not exist) in terminal from 12.Modules java -p mods -m zoo.animal.care/zoo.animal.care.medical.Diet the word Diet should be printed in the console

If the program runs properly, there should be no reason for vsc to mark an error in red, such as in the module-info.java file in the care folder that says that the package zoo.animal.care.medical does not exist. Your help please

Piste de recherche

Reproduisez le rapport à l’aide des fichiers affichés module-info.java, Task.java, HippoBirthday.java et Diet.java, ainsi que des commandes javac, jar et java indiquées. Comparez la compilation réussie dans le terminal avec le diagnostic en rouge sur care/module-info.java, puis suivez la manière dont l’extension Java gère cette disposition de modules. C’est terminé lorsque le package valide n’est plus signalé comme manquant, ou lorsque le problème fait l’objet d’une explication documentée si le diagnostic est attendu.
