将jar文件中的类导入IntelliJ

Question

I'm having difficulty importing a class and method from a jar file I've created into my .java file in IntelliJ. It's a simple method to print to the console and contains the following.

public class gazutils {
    public static print(Object text){
        System.out.println(text);
    }
}

Whenever I try to import this with

import gazutils.*

I get cannot resolve symbol 'gazutils'

I am creating the .jar file and importing it into the project structure as follows:

Project Structure > Artefacts > Add > Jar > From modules with Dependencies

Then

Build > Build Artefacts

I then copy the .jar file into the project structure I want to use the .jar file in and

Right Click the jar > Add as Library

This adds it as a dependency, but I still don't seem to be able to access or import the class or method

Answer 1

This is because gazutils is a class and not the name of a package

and import gazutils.* implies import all that is part of the package gazutils ; which doesn't exist , and hence the failure!

A good Idea is to put your class in a package and then import that packageName.yourClassName

So :

package somePackage;
//imports and other stuff...
public class gazutils {
public static print(Object text){
    System.out.println(text);
}
}

In your target where you put the Jar :

import somePackage.gazutils;
