Requirements:

• Linux, MacOS or WSL

Installation:

Automatic installation:

Important: uninstall any previous installation.

• Script will be installed to ~/.local/opt/jdtls-launcher
• A symlink called jdtls will be created in ~/.local/bin/jdtls

Linux / MacOS / WSL:

1. Run the installation script:

   curl https://raw.githubusercontent.com/eruizc-dev/jdtls-launcher/master/install.sh | bash
   

2. Add ~/.local/bin to your path

   # .bashrc, .zshrc or whatever shell you use
   export PATH=$PATH:$HOME/.local/bin

Custom install location:

Append -s /path/to/dir to the installation command

• A directory called jdtls-launcher will be created inside that directory
• A symlink will still be created to the same location

Manual Installation:

1. Download source code from releases or directly from the master branch
2. Unzip it and place jdtls-launcher.sh script in your desired install location
3. Run the script with --install option to install jdtls and lombook alongside the script in a directory called jdtls (user must have write permissions)
4. Run the script jdtls-launcher.sh without arguments to start the language server

Update

To update jdtls and lombook it's as simple as jdtls --update

You can always check what version you have installed with jdtls --version command.

To update jdtls-launcher you have to manually uninstall and reinstall

Uninstall

Remove symlink and jdtls-launcher directory with rm -rf.

• Symlink locations can be found using where jdtls or which jdtls
• Install location can be found using dirname $(realpath jdtls)

Editor configuration:

Neovim with lspconfig

Add the following to your init.vim

lua require'lspconfig'.jdtls.setup{
\   cmd = { 'jdtls' },
\   root_dir = function(fname)
\      return require'lspconfig'.util.root_pattern('pom.xml', 'gradle.build', '.git')(fname) or vim.fn.getcwd()
\   end
