|
|
---
|
|
--- Language server for Java.
|
|
---
|
|
--- IMPORTANT: If you want all the features jdtls has to offer, [nvim-jdtls](https://github.com/mfussenegger/nvim-jdtls)
|
|
--- is highly recommended. If all you need is diagnostics, completion, imports, gotos and formatting and some code actions
|
|
--- you can keep reading here.
|
|
---
|
|
--- For manual installation you can download precompiled binaries from the
|
|
--- [official downloads site](http://download.eclipse.org/jdtls/snapshots/?d)
|
|
--- and ensure that the `PATH` variable contains the `bin` directory of the extracted archive.
|
|
---
|
|
--- ```lua
|
|
--- -- init.lua
|
|
--- vim.lsp.enable('jdtls')
|
|
--- ```
|
|
---
|
|
--- You can also pass extra custom jvm arguments with the JDTLS_JVM_ARGS environment variable as a space separated list of arguments,
|
|
--- that will be converted to multiple --jvm-arg=<param> args when passed to the jdtls script. This will allow for example tweaking
|
|
--- the jvm arguments or integration with external tools like lombok:
|
|
---
|
|
--- ```sh
|
|
--- export JDTLS_JVM_ARGS="-javaagent:$HOME/.local/share/java/lombok.jar"
|
|
--- ```
|
|
---
|
|
--- For automatic installation you can use the following unofficial installers/launchers under your own risk:
|
|
--- - [jdtls-launcher](https://github.com/eruizc-dev/jdtls-launcher) (Includes lombok support by default)
|
|
--- ```lua
|
|
--- -- init.lua
|
|
--- vim.lsp.config('jdtls', { cmd = { 'jdtls' } })
|
|
--- ```
