How to rename a method/field from Eclipse when not declared

Question

I'm not a newbie of Java and Eclipse, this question is not as easy as Alt + Shift + R or Refactor > Rename

Assume there is a method in utils.jar .

public class A {
    public void taste() {} 
}

Then I used it in current project.

public class taste {
    public static void taste() {
        A taste = new A();
        return taste.taste(); 
    }
}

OK, now I found taste in utils.jar is not the word I want, then I changed the utils.jar to test :

public class A {
    public void test() {} 
}

So, after that, how could I change A.taste() to A.test() precisely just like use Alt + Shift + R ?

public class taste {
    public static void taste() {
        A taste = new A();
        return taste.test();  // only change function A.taste to test
    }
}

I found that Search > Java can find the A.taste function precisely, but I have no idea how to replace all of it to test .

Answer 1

在这种情况下， Alt + Shift + R可能很有用。

1. Put the old source code of A in your project. Eg src/some_package/A.java

   This overrides the class from the library utils.jar

2. Use the refactoring tool to rename the method.

   You can do this now, because the source code of A is available

3. remove the source code of A from your project
4. add the updated lib utils.jar to your project
