Unknown symbols don't throw an error about lsp-java HOT 7 CLOSED

Doesn't work for me as well. Don't know how to setup :(

Errors:

user-error: No definitions found for: foo
Error from the Language Server: no identifier found (Unknown error)

from lsp-java.

Can you try adding this to your .emacs and see whether that fixes it?

(require 'flycheck)
(lsp-flycheck-add-mode 'java-mode)
(global-flycheck-mode 1)

from lsp-java.

Nop for me. I think it's not related to flycheck settings.
Waiting for @tepf 's feedback.

Do unknown symbols show errors in VSCode?

I digg out the root cause finnaly. I fount this message in *lsp-java stderr*.

Error: Unable to access jarfile Found more than one java language server entry points: (/home/vincent/.emacs.d/eclipse.jdt.ls/server/plugins/org.eclipse.equinox.launcher_1.4.0.v20161219-1356.jar /home/vincent/.emacs.d/eclipse.jdt.ls/server/plugins/org.eclipse.equinox.launcher_1.4.0.v20161219-1356.jar.pack.gz)

I deleted all *.pack.gz* in the plugins folder, and restart Emacs. It works well now.

Deleting *pack.gz files in the plugins directory made the plugin work. But now Emacs freezes sometimes when I try to tab complete. It's generally pretty slow as well. Furthermore it still doesn't detect simple semantic errors like the one in my first post.

Fixed with #21 . The warnings/errors are not displayed when the file that is currently open does not have classpath configured. In latest lsp-java you have to configure the projects roots:

(setq lsp-java--workspace-folders (list "/path/to/project1"
                                        "/path/to/project2"
                                        ...))
