After saving a file for the fisrt time, syntax errors will not be highlight omitted till the next save. also autocompleteing will not work.

[masalkhi]

Everything is working perfectly, until saving a file for the first time, the syntax errors will not be highlight or omitted until typing C-x C-s . also the auto-completion will not work after the first save. any any suggestions how I to solve this.

before the first save, everything is good:

now saving for the fist time and after that removing the text, the highlighting will not be omitted:

typing C-x C-s and after that the highlighted syntax errors will be omitted:

writing some text (no syntax error will show)

typing C-x C-s again and all the syntax errors will be highlighted

The workspace directory of the jdtls is the same for the eclipse IDE installed on my PC.

and if there is a way to import an already existed maven project to lsp-java I would appreciate.

is it reproducible after M-x lsp-start-plain?

after typing the the command, a new frame was opened:

I got the following in the *Compile-Log* buffer:

Press c - you can ignore that error

[yyoncho]

@ericdallo seems like lsp-dart does not work on 26.3

[ericdallo]

CI seems to compile it properly, why do you think this @yyoncho ?

Debugger entered--Lisp error: (void-function rx-let)

Ah, it is dart-mode actually causing the trouble.

[masalkhi]

I have installed 26.1 from the source code, I have typed the the command, no errors was shown and it opened a new frame. I had to specify my lisp file with the command load-file because it did not load my init.el file. then I have entered the command lsp-mode, it tells me that it Disconnected. and in the other frame is just the same.

and I have installed the 27.1 too I got the following in the *ERROR* buffer, when typing lsp-start-plain
