java-deps.nvim

A Neovim plugin for viewing Java project dependencies, inspired by vscode-java-dependency.

Features

• View project dependencies in a tree structure.
• Expand and collapse dependency nodes.
• Use jdtls to get dependency information.
• Use snacks.nvim to build the UI.

Installation

jdtls

Ensure that the com.microsoft.jdtls.ext.core extension jar from vscode-java-dependency is loaded into your jdtls.

• If you have vscode-java-dependency installed in VS Code, it is located at .vscode/extensions/vscjava.vscode-java-dependency-{{version}}-universal/server/com.microsoft.jdtls.ext.core-{{version}}.jar
• Install the vscode-java-dependency package via mason.

local java_deps_path = require("mason-registry")
    .get_package("vscode-java-dependency")
    :get_install_path() .. "/extension/server/com.microsoft.jdtls.ext.core-*.jar"
-- or
local java_deps_path = ".vscode/extensions/vscjava.vscode-java-dependency-{{version}}-universal/server/com.microsoft.jdtls.ext.core-{{version}}.jar"

nvim-jdtls example configuration

-- Add the vscode-java-dependency jdtls extension jar
local jdtls_config = {
  bundles = { java_deps_path }
}

nvim-lspconfig example configuration

-- Add the vscode-java-dependency jdtls extension jar
require("lspconfig").jdtls.setup {
  init_options = {
    bundles = { java_deps_path },
  },
}

lazy.nvim

{
  {
    "g0ne150/java-deps.nvim",
    dependencies = {
      "folke/snacks.nvim",
      {
        "mason-org/mason.nvim",
        opts = { ensure_installed = { "vscode-java-dependency" } },
      },
    },
    config = function()
    end,
  },
}

Usage

• Run :JavaDepsView to open the dependency view.
• Run :JavaDepsViewRefresh to clear the cache and refresh the dependency view. This is useful when you have updated your dependencies in pom.xml or build.gradle.

Keybindings

• h: Collapse the current node. If the current node is already collapsed or cannot be expanded, collapse the parent node.
• l/o/<CR>: Expand the current node.

Acknowledgements

• vscode-java-dependency: Provided the initial idea and the jdtls extension.
• snacks.nvim: Provided the powerful picker UI framework.
