Get the base package in Java project

How do I programmatically get the base package of a Java project?

For example I have the following:

my-app
- src
 - main
  - java
   - hello
    - world
     - util
     - exception
     - misc

I want to get: hello.world.

Thank you.

There is a class - Class , that can do this:

Class c = Class.forName("MyClass"); // if you want to specify a class
Class c = this.getClass();          // if you want to use the current class

System.out.println("Package: "+c.getPackage()+"\nClass: "+c.getSimpleName()+"\nFull Identifier: "+c.getName());

c represented the class MyClass in the package mypackage, the above code would print:

Package: mypackage

Class: MyClass

Full Identifier: mypackage.MyClass

You can take this information and modify it in your way.

Suppose we have a class called HelloWorld and packaged under:

package hello.world.test;

then

HelloWorld.class.getPackage().getName()

will give you hello.world.test as package name.

In your case, probably you need to remove the last level as:

basePackageName = packageName.substring(0, packageName.lastIndexOf("."));

and have hello.world.
