Currently trying to add H2 Database support with my mod. I've shaded the h2 database engine in my build.gradle like so:

shadowJar {
    dependencies {
        include dependency("org.json:json:20180813"),
        include dependency("com.h2database:h2:1.0.60")
    }
    relocate("org.json", "shaded.org.json")
    relocate("com.h2database","shaded.com.h2database")
}

...
  
reobf {
    shadowJar {
        mappingType = 'SEARGE'
    }
}

 

Issue is, everytime I attempt to establish a connection using my H2Connection class like so:

H2Connection db = new H2Connection("jdbc:h2:D:/H2db/test/test", "admin", "password");

 

I get an error saying: java.sql.SQLException: No suitable driver found for jdbc:h2:D:/H2db/test/test

Anyone know whats up? Am I doing this right?

 

This is my H2Connectionclass:

public class H2Connection {
    private Connection conn;

    public H2Connection() {}
    public H2Connection(String url, String user, String pass) throws SQLException, ClassNotFoundException {
        connect(url, user, pass);
    }
    public void connect(String url, String user, String pass) throws SQLException, ClassNotFoundException {
        conn = DriverManager.getConnection(url,user,pass);
    }
    public ResultSet query(String query) throws SQLException {
        return conn.createStatement().executeQuery(query);
    }
}

This file will no longer be correct after your relocation.

What does that mean then? Do I have to reference the driver using Class.forName() and include the "shaded" part?

Realised my build.gradle was missing some things that lead to it not properly shading. It's fixed now!
