How to Switch Projects and Update Filepaths Simultaneously in =dape=

[LuciusChen]

Hello,

I am currently using the =dape= package and have encountered an issue when switching projects. Despite changing the project, the =filepath= does not update accordingly. Here is a snippet of my configuration:

(defun jdtls-command-contact (&optional interactive)
  (let* ((jdtls-cache-dir (file-name-concat user-emacs-directory "cache" "lsp-cache"))
         (project-dir (file-name-nondirectory (directory-file-name (project-root (project-current)))))
         (data-dir (expand-file-name (file-name-concat jdtls-cache-dir (md5 project-dir))))
         (jvm-args `(,(concat "-javaagent:" (expand-file-name "~/.m2/repository/org/projectlombok/lombok/1.18.30/lombok-1.18.30.jar"))
                     "-Xmx8G"
                     ;; "-XX:+UseG1GC"
                     "-XX:+UseZGC"
                     "-XX:+UseStringDeduplication"
                     ;; "-XX:FreqInlineSize=325"
                     ;; "-XX:MaxInlineLevel=9"
                     "-XX:+UseCompressedOops"))
         (jvm-args (mapcar (lambda (arg) (concat "--jvm-arg=" arg)) jvm-args))
         ;; tell jdtls the data directory and jvm args
         (contact (append '("jdtls")
                          jvm-args
                          `("-data" ,data-dir)
                          `(:initializationOptions
                            (:bundles
                             [,(file-truename "~/.m2/repository/com/microsoft/java/com.microsoft.java.debug.plugin/0.53.0/com.microsoft.java.debug.plugin-0.53.0.jar")])))))
    contact))

I am using the built-in =project= package in Emacs.

Hi. I am not sure if I follow. Would it be possible for you to illustrate your issue with an screenshot?

[LuciusChen]

When I started dape in the demo project and then switched to the sky project to start dape again, the filepatch as well as :mainClass and :projectName still had the information from the demo project. I had to manually modify them to use dape for debugging in the sky project.

Dape tries to be ergonomic and displays the last "dape" command.

Delete everything except the adapter name jdtls which forces dapeto re-do lookup for :filePath, :mainClassand :projectName.

There is actually an undocumented keybind C-c C-k (in the minibuffer) which accomplishes this.

Nice looking Emacs btw!
