Whether to enable https://projects.eclipse.org/projects/eclipse.jdt.ls

Language server for Java.

IMPORTANT: If you want all the features jdtls has to offer, 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 and ensure that the PATH variable contains the bin directory of the extracted archive.

  -- init.lua
  require'lspconfig'.jdtls.setup{}

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:

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 (Includes lombok support by default)

  -- init.lua
  require'lspconfig'.jdtls.setup{ cmd = { 'jdtls' } }
