No error for missing import

[anthonyvdotbe]

As a follow-up to #1265: sometimes there's no error reported for a missing import

Environment

• Operating System: Windows 10
• JDK version: JDK 13
• Visual Studio Code version: VS Code 1.42.0
• Java extension version: 0.55.1

Steps To Reproduce

Copy-paste the code below in a Java file. Note that there's no error reported for the missing import of java.util.List

import java.util.Map;

class Test {

    static class Employee {

        final String name;

        Employee(String name) {
            this.name = name;
        }

        String name() {
            return name;
        }

    }

    public static void main(String... args) {
        var totals = Map.of(new Employee("John"), 0);
        Employee e = new Employee("Jane");
        //totals.put(e., 0);
        List.of("foo").forEach(item -> {
            totals.put(null, 0);
        });
    }

}

Current Result

Expected Result

An error is reported on the usage of List.of

I can't reproduce the issue.

Could you attach a project example?

Most likely it's because I was using a stand-alone file, and so had an "incomplete classpath", isn't it? If so, you can close this issue.

@anthonyvdotbe When you open an external Java (aka stand-alone) file in VS Code, we only show syntax errors. The quickfix for missing import won't be enabled. If you want to import all missing types quickly, you can use the global Organize imports command (Shift + Alt + O) for that.

@testforstephen Thanks for the tip. While I know about the command, because there are no visual clues that doing Organize imports might help, I simply don't think of doing it. I filed #1270 as a follow-up issue to improve support for standalone files.
