Pasting the additional key mappings leads to errors

[fjbaldon]

nnoremap <A-o> <Cmd>lua require'jdtls'.organize_imports()<CR>
nnoremap crv <Cmd>lua require('jdtls').extract_variable()<CR>
vnoremap crv <Esc><Cmd>lua require('jdtls').extract_variable(true)<CR>
nnoremap crc <Cmd>lua require('jdtls').extract_constant()<CR>
vnoremap crc <Esc><Cmd>lua require('jdtls').extract_constant(true)<CR>
vnoremap crm <Esc><Cmd>lua require('jdtls').extract_method(true)<CR>

Need some helping setting this up.

The keymap examples are in vimscript, not lua. You'll either have to translate them to use vim.keymap.set or wrap it in vim.cmd:

vim.cmd [[
nnoremap <A-o> <Cmd>lua require'jdtls'.organize_imports()<CR>
nnoremap crv <Cmd>lua require('jdtls').extract_variable()<CR>
vnoremap crv <Esc><Cmd>lua require('jdtls').extract_variable(true)<CR>
nnoremap crc <Cmd>lua require('jdtls').extract_constant()<CR>
vnoremap crc <Esc><Cmd>lua require('jdtls').extract_constant(true)<CR>
vnoremap crm <Esc><Cmd>lua require('jdtls').extract_method(true)<CR>
]]
