Lombok + javac: cannot find symbol

Question

I'm trying to get started with Lombok. As the official demo and the documentation state one should be able to compile a class with lombok annotation with following simple steps:

Create a class and include @Data annotation in the code. Should be something like this

public @Data class Test {
    private final String name;

    public static void main(String[] args) {
        System.out.println(new Test("name"));
    }
}

Compile with javac and lombok.jar put into classpath:
```
javac -cp lombok.jar Test.java -verbose  
```

Doing so unfortunately I'm running into an error:

Round 1:
        input files: {test.Test}
        annotations: [Data]
        last round: false
Processor lombok.launch.AnnotationProcessorHider$AnnotationProcessor matches [Data] and returns false.

public @Data class Test {
        ^
  symbol: class Data

I have javac 1.8.0_144, lombok 1.18.0 and running it on Windows 8.1 Pro.

Any ideas would be very helpful!

@SzymonStepniak Yes, I've already tried this option but got the same error. — Pavel Smirnov, Jul 09 '18 at 09:19
Check if `import lombok.Data` is present in your class. `annotations: [Data]` suggests like there is an import missing. — Szymon Stepniak, Jul 09 '18 at 09:23
@SzymonStepniak annotations are modifiers and the order of the modifiers is not relevant, so you can write `public @Data` or `@Data public`, as you like. — Holger, Jul 09 '18 at 14:28

The cause of compilation error was missed import:

import lombok.Data

Thanks to @SzymonStepniak who caught the problem.
