• How to use nvim-jdtls for Java and nvim-lspconfig for everything else?
  2 projects | /r/neovim | 8 Apr 2023

  I installed eclipse jdtls which worked for Java, but I was not able to go to definitions for methods/classes outside of my project (ie, libraries and such, something like in IntelliJ where you can go to the definition or implementation for the library code), so I thought it may be a limitation of nvim-lspconfig

• Minecraft modding without the use of intellij

  You can absolutely just use Gradle on the command line, and use a language server to get code intelligence in pretty much any editor you like. IntelliJ is very nice, especially for refactoring, but it doesn't have a giant advantage over any other editor, as long as you're sticking to mostly Java.

• Where does the dislike/hate for Java come from?

  Try neovim. Builtin support for language servers which provide the basis for IDE functionality, autocomplete, auto import, code actions, refactoring, etc. I believe VSCode uses jdtls on the backend and you can use the same thing with neovim.

• java 19 in latest eclipse IDE

  Is seems like valid manual to start language server here https://github.com/eclipse/eclipse.jdt.ls. Not sure what you mean by "starting it with other editors" though. It should be covered by editor own integration with the given LS.

• What do you tells VSCode and Jetbrains naysayers
  1 project | /r/emacs | 7 Oct 2022

  But all of the above to say that Emacs can have the ability to some of if not more than VSCode. As others have said, the Jetbrains IDEs are a different story. They're built to actually understand the code you're writing. It's quite possible, with features like auto-insert and skeletons, to replicate some of the functionality that, say, IntelliJ does. For example, say you find-file into a new file for some Java project. When you first enter the buffer, you could setup a prompt to create a class, enum, interface etc. and then upon a selection, you have the basic relevant code for whatever the selection was made auto-inserted. Or you could just quit the prompt with C-g. Granted that takes some time to set up as well as recreating other smaller features that IntelliJ has. JDTLS can do some of this, but at the end of the day it's not a replacement for IntelliJ and I don't think JDTLS intends to be such.

  Just the other day I tested VS Code Java again and apparently the Red Hat team that did the Java language support has gotten some level of null analysis turned on now. Thus I assume the Eclipse LSP https://github.com/eclipse/eclipse.jdt.ls has that support now.
