Build the server locally

[XiaowenHu96]

I want to use the language server with vim, is there any way I can build the project locally?

I have no experience with Gradle-based projects and had no luck with gradle build or gradlew wrapper.

* What went wrong:
Could not open settings generic class cache for settings file '/home/xiaowen/souffle-lsp-plugin/settings.gradle' (/home/xiaowen/.gradle/caches/7.5.1/scripts/1lepdxfcl23lx79rdpsew90n).
> BUG! exception in phase 'semantic analysis' in source unit '_BuildScript_' Unsupported class file major version 63

* Try:
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.

* Get more help at https://help.gradle.org

There is no need to build the server yourself. The process is already complete, but I had the resulting jar under .gitignore, oops. Now it is visible.

To integrate the server with a client you need to set up a script running .jar file as I do for the VS code extension in https://github.com/jdaridis/souffle-lsp-plugin/blob/master/src/main/vs-code/extension.ts line 74-79.
For Vim I imagine there is a similar process, you have to write a script for vim to know when it detects a .dl file to run the .jar file. From a quick Google search, I see that the Vim team has good documentation on how to implement the client side

Thanks for the clear instruction, I'll give it a try and get back to you next week.

I added the jar file as a release to make it easier to find.

Also for completeness, to build the java source code run ./gradlew jar on the top level.
I updated the README file with more instructions on how to build and run the standalone server.
