[BUG] Syntax highlighting for lombok annotations is broken

[humphreygao]

Describe the bug
In Eclipse IDE, syntax coloring for some lombok annotations(such as @Data、@Slf4j、@ToString、@EqualsAndHashCode) are not correct.

To Reproduce

1. Install Eclipse lombok plug-in.
2. Via Window > Preferences > Java > Editor > Syntax Coloring, choose the Java > Annotations from preference page and change the color of annotations(for example, orange).

Version info (please complete the following information):

• Lombok version: 1.18.12
• Platform: Eclipse IDE 2020-06

I can not reproduce this issue.

Can you check if there is an error message? (Window > Show View > Error Log)

I have seen similar things, and I think it dates back to at least lombok 1.18.2 and older eclipse versions. However, I was unable to identify a common pattern or a way to reproduce.

Probably some of the positions of the generated AST nodes are off. We've also seen similar problems with @Cleanup, but have not yet put time in it to find the wrong positions yet

@Rawi01 There is no error.

My computer OS is Windows 10. The syntax coloring is correct before the plugin was installed. You can try annotations one by one to see which annotation's color is wrong. When there are several annotations, some annotation's color may be okay(in the picture, @Data and @ToString is okay but not okay when they are alone).

Sometimes move the annotations up and down(using Alt + Up/Down shortcut) may affect the annotation color.

Interesting, I know that this can happen if there are errors.

I just tried it using a new eclipse version + lombok 1.18.12 and it works as expected.

I'm going to guess that this is either fixed or at least got a lot bitter via @Rawi01's PR (#2984).

@rzwitserloot I think this has improved, but I'm still seeing issues with annotations like @Value, @With, and @Builder.

Here are some screenshots that could shed some light 🙂

I hope this helps!
