`groovyls` can be installed by following the instructions [here](https://github.com/prominic/groovy-language-server.git#build).

If you have installed groovy language server, you can set the `cmd` custom path as follow:

```lua
require'lspconfig'.groovyls.setup{
    -- Unix
    cmd = { "java", "-jar", "path/to/groovyls/groovy-language-server-all.jar" },
    ...
}
```
]],
  },
}
