Emacs配置LSP-Metals时semgrep-ls启动失败问题求助

配置背景 #

我在Emacs中配置lsp-metals时，直接使用官方页面提供的配置代码：

(use-package lsp-metals
  :ensure t
  :custom
  ;; You might set metals server options via -J arguments. This might not always work, for instance when
  ;; metals is installed using nix. In this case you can use JAVA_TOOL_OPTIONS environment variable.
  (lsp-metals-server-args '(;; Metals claims to support range formatting by default but it supports range
                            ;; formatting of multiline strings only. You might want to disable it so that
                            ;; emacs can use indentation provided by scala-mode.
                            "-J-Dmetals.allow-multiline-string-formatting=off"
                            ;; Enable unicode icons. But be warned that emacs might not render unicode
                            ;; correctly in all cases.
                            "-J-Dmetals.icons=unicode"))
  ;; In case you want semantic highlighting. This also has to be enabled in lsp-mode using
  ;; `lsp-semantic-tokens-enable' variable. Also you might want to disable highlighting of modifiers
  ;; setting `lsp-semantic-tokens-apply-modifiers' to `nil' because metals sends `abstract' modifier
  ;; which is mapped to `keyword' face.
  (lsp-metals-enable-semantic-highlighting t)
  :hook (scala-mode . lsp))

错误现象 #

打开Scala文件或启动scala-mode时，迷你缓冲区弹出错误：

Server semgrep-ls:1389372 exited (check corresponding stderr buffer for details). Do you want to restart it? (y or n) 

对应的*semgrep-ls:stderr*缓冲区内容：

Process semgrep-ls stderr finished
Fatal error: exception Git_wrapper.Error("run ['git' '-C' '/home/jake/src/helloworld' 'rev-parse'
     '--is-inside-work-tree']: No such file or directory")
Raised at Yojson__Safe.__ocaml_lex_read_object_sep_rec in file "lib/read.mll", line 698, characters 13-43
Called from Yojson__Safe.__ocaml_lex_read_json_rec in file "lib/read.mll", line 226, characters 23-47

注：报错中提到的/home/jake/src/helloworld路径实际存在，且我手动执行semgrep lsp --debug能正常启动服务，但Emacs无法复用该服务。

临时解决方法 #

禁用semgrep-ls客户端后问题消失：

(setq lsp-disabled-clients '(semgrep-ls))
