Autocomplete parameters

[cshjsc]

Hi, I'm not sure if this is a problem with nvim-jdtls or not but when I select a method with autocomplete (nvim-cmp) I don't get the parameters filled automatically like in other languages.
Instead of for example myMethod(a,b,c). I just get mymethod . I don't know if its a problem with nvim-cmp or with the lsp that doesn't provide the information to cmp.

You have to setup snippet support for your completion plugin.

I have the same problem and I am pretty confused. using jdtls without this plugin gives me the wanted autocompletion (with a '~' in the completion pop up/drop down).

at what point do I need to include nvim-jdtls into cmp? Is there any .lua example for that?

@mfussenegger I am having the same issue... Could you please clarify again? The video you sent is marked as corrupted.

Got it working

How to enable autocomplete for parameters (arguments are autofilled with placeholders, you are able to use TAB to navigate / jump to next argument && ENTER to change placeholder value)

You have to add snippentSupport in your nvim/ftplugin/java.lua

local config = {
  ...
  capabilities = {
    workspace = {
      configuration = true,
    },
    textDocument = {
      completion = {
        completionItem = {
          snippentSupport = true,
        },
      },
    },
  },
}
config.capabilities = require("cmp_nvim_lsp").default_capabilities(vim.lsp.protocol.make_client_capabilities())
require("jdtls").start_or_attach(config)

Working great thanks!

Hello!

I faced the same problem, and implementing the suggested config made it work, but I just needed to add the following line:

config.capabilities = require("cmp_nvim_lsp").default_capabilities(vim.lsp.protocol.make_client_capabilities())

Is the "capability" section in the config really needed?

local config = {
  ...
  capabilities = {
    workspace = {
      configuration = true,
    },
    textDocument = {
      completion = {
        completionItem = {
          snippentSupport = true,
        },
      },
    },
  },
}
config.capabilities = require("cmp_nvim_lsp").default_capabilities(vim.lsp.protocol.make_client_capabilities())
require("jdtls").start_or_attach(config)
