You don't have to manually install JDTLS, it is included with the plugin. Is there a reason you're using the latest snapshot of JDTLS?

My coc-java instalation is using jdtls version 0.29.0.201811280615 while the lastest version is 0.35.0.201903050055. As I did not figured out how to upgrade coc-java's jdtls, I was trying to keep jdtls up-to-date myself.
I don't know if :CocUpdateSync would upgrade jdtls but in my machine this command gives the following messages:
Error detected while processing function coc#rpc#request[2]..35_request:
line 7: connect ETIMEDOUT 192.30.253.117:443

It only upgrade itself.

You have JDTLS_CLIENT_PORT in your environment variable, which is used for local language server, but it can't connect to server by use that port.

My config is just as #11 (comment) described.

The error means connection to server is closed, but I don't know why.
Could you try get the output from language server https://github.com/neoclide/coc.nvim/wiki/Debug-language-server#using-output-channel?
Or try to use language server downloaded by coc-java instead of use java.jdt.ls.home

It's no problem using jdtls downloaded by coc-java. But I found it can't complete third-party libraries. I've no idea whether the problem is jdtls's or coc-java's. I use eclipse plugin of gradle to manage dependences.

If I don't understand wrongly, it only supports basic Java gradle applications? My project is just java-application with groovy build script DSL, not Android project.

I've tested it with sample gradle based project https://github.com/web3j/sample-project-gradle, it works as expected for me, although it takes some time to build the project the first time.

I think the problem is latest jdt.ls doesn't have support for gradle version <= 2.4, you have to upgrade gradle.
Run :CocList diagnostics to get the error message.
