Auto-import was not triggered automatically in some cases

Environment

• Operating System: Win/Mac/Linux
• JDK version: 13/12/8
• Visual Studio Code version:1.39.2
• Java extension version:0.51.0

Steps To Reproduce

1. Make sure java.actionsOnPaste.organizeImports in settings is true.
2. New Foo.java with codes as below:

import java.io.File;
 
public class Foo {
 
     public static void main(String[] args) {
        File f =new File("A.txt");
    }
}

Result:

1. If copy the main method to another empty java file Auto-import was not triggered automatically.

2. If copy the all class to another empty java file Auto-import was triggered automatically.

The feature is expected to work when pasting into an empty file. It seems you’re trying to paste in a file that already has a class definition, so it’s not empty.

Triggering autoimport when pasting in non-empty files might cause some issues eventually, that’s why I’d prefer not to enable it at this time.
