Hi @yixuan004,
I can only provide you with the answer to a previous question which is mostly overlapping:
Third-party analyzers are not supported in SonarLint
I could not phrase it any better than this and even though the post is two years old, nothing has changed on that policy.
The plugins you developed, do they extend the official Sonar analyzers? If not they won’t work in SonarLint and if they do (like the extension to the Java analyzer you mention), they will only work in connected mode.
Best,
Tobias
