Hi~
I try to use the kotlin settings for a gradle project, but there is no semantic completion at all. The stderr log file output as below:

After some analysis, I finally found that this error is caused by the missing of .ycm_extra_conf.py file, YCM treats the path of conf file as workspace of the project and send it to kotlin-language-server, but the server does not set properly try-catch block for file parsing. After put .ycm_extra_conf.py into the root path of gradle project, everything work fine now ;)

Thus for an easy start for new users, I think it's better to add this notice in README file. And I provide a pr for it ;)
