[FIXED] VSCode | Basic compiling issues with Maven

Issue

This is my first Java project using Maven (Jakarta and PostgreSQL dependencies) in which I am struggling with many basic compiling issues. I am also using the newest VSCode as an editor.

First issue

The terminal tries to find Main.java at '...\Projeto-POO-2022.2' when it should actually access '...\Projeto-POO-2022.2\javarental\src\main\java\poo' where the file currently lies.

I have already tried manually setting up terminal.integrated.cwd to access the right path with no success.

Second issue

Even using 'cd javarental\src\main\java\poo' to access the right path and then running the project with 'javac Main.java' the following errors come up:

Main.java:3: error: package jakarta.persistence does not exist
import jakarta.persistence.EntityManager;
                          ^
Main.java:4: error: package jakarta.persistence does not exist
import jakarta.persistence.EntityManagerFactory;
                          ^
Main.java:5: error: package jakarta.persistence does not exist
import jakarta.persistence.Persistence;
                          ^
Main.java:7: error: package poo.models does not exist
import poo.models.Usuario;
                 ^
Main.java:11: error: cannot find symbol
        Usuario user = new Usuario();
        ^
  symbol:   class Usuario
  location: class Main
Main.java:11: error: cannot find symbol
        Usuario user = new Usuario();
                           ^
  symbol:   class Usuario
  location: class Main
Main.java:19: error: cannot find symbol
        EntityManagerFactory emf = Persistence.createEntityManagerFactory("default");
        ^
  symbol:   class EntityManagerFactory
  location: class Main
Main.java:19: error: cannot find symbol
        EntityManagerFactory emf = Persistence.createEntityManagerFactory("default");
                                   ^
  symbol:   variable Persistence
  location: class Main
Main.java:20: error: cannot find symbol
        EntityManager em = emf.createEntityManager();
        ^
  symbol:   class EntityManager
  location: class Main
9 errors

For addition, this is the section of code Main.java:

package poo;

import jakarta.persistence.EntityManager;
import jakarta.persistence.EntityManagerFactory;
import jakarta.persistence.Persistence;
import poo.models.Usuario;

public class Main {
    public static void main(String[] args) {
        Usuario user = new Usuario();
        user.setEmail("[email protected]");
        user.setNomeUsuario("user_3");
        user.setNome("User");
        user.setSenha("senha");
        user.setCpf(123);


        EntityManagerFactory emf = Persistence.createEntityManagerFactory("default");
        EntityManager em = emf.createEntityManager();
    
        em.close();
    }
}

And this is my pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

</project>

Don't know if it has something to do with but I've imported and synced this project straight from GitHub. I've also tried rebuilding it a few times with no luck. Any help would be appreciated.

Solution

Somehow I got it working through the following steps:

1. Delete the project folder;
2. Remove any invalid characters from the new project folder path;
3. Create a new folder;
4. Clone once again the repository from GitHub into the new folder.
