Unable to access to jar file

[windrg]

Summary

Hi,
Whenever opening a plantuml file, it shows "Error : Unable to access to jar file ..."

I didn't change anything except this

(use-package plantuml-mode
     :ensure t
      :init
       (setq plantuml-jar-path "~/.emacs.d/orgtools/plantuml.jar")
      :config
      (add-to-list 'auto-mode-alist '("\\.uml\\'" . plantuml-mode))
      (add-to-list 'auto-mode-alist '("\\.plantuml\\'" . plantuml-mode))
  )

However I could launch it without any problem in a terminal.
Could you let me know what could be the problem on opening uml files in Emacs, please??

[windrg]

I've added this config but it still complains like the above.

(setq plantuml-java-args '("-jar"))

That error message is displayed when plantuml-mode cannot find the PlantUML jar file specified at plantuml-jar-path. Could you please specify:

• what environment are you running (OS / Emacs version)
• the rest of the error message (i.e. after Unable to access jar file..)

Of course, make sure that the file at ~/.emacs.d/orgtools/plantuml.jar actually exists and is the version of PlantUML that you want to use.

Hi,
After updating this package to the recent one, I've tested it again.
And here are my environment and test result

• OS : Ubuntu 16.04 / Emacs 25.1

• Error Messages
  . message buffer
  error in process sentinel: PLANTUML Preview failed: exited abnormally with code 1

  . plantuml message buffer
  Command is [-jar|~/.emacs.d/orgtools/plantuml.jar|-charset|UTF-8|-language]

I've double-checked that it exists in ~/.emacs.d/orgtools/plantuml.jar.

[windrg]

I've found somethig new in Plantuml Preview which could be a clue for this problem.

Error: Unable to access jarfile \~/.emacs.d/orgtools/plantuml.jar

Could you figure out why it has the prefix / in that path, please?

[skuro]

Mhhh that might be because of shell-quote-argument. Can you try with the full /home/<user>/.emacs.d/orgtools/plantuml.jar path?

[windrg]

Yes, it was the culprit. and after doing some tests, I've figured out the below syntax is more appropirate.

(setq plantuml-jar-path (expand-file-name "~/.emacs.d/orgtools/plantuml.jar"))

Thanks for helping me.

[skuro]

Glad to hear that you found a solution, but I'd like to keep the issue open: it would be best for plantuml-mode to actually support ~/path/to/plantuml.jar styles of configurations.

[skuro]

As of ba7420b paths with ~ should be properly expanded, and version v1.2.1was just released to include the change.

Thanks for all the testing!
