Downloading the jar file appears to be blocking

Great plugin. Thanks.

When I run the check the first time, it goes to download the jar file, which is fine. But that operation seems to be blocking. I can't do anything inside of vim. There is just the Downloading jar file from ... in the status bar. Once the download is done, everything is back to normal. This isn't a big deal on a fast internet connection, but on a slow one, this can take a while.

Hi, I have the same issue too. I solved it by download it manually.

1. Download LanguageTool-stable.zip from here.
2. unzip the zip file, then copy the whole unzipped file to ~/your/grammous-vim/root/misc/
3. try :GrammousCheck again, everything will be fine.

PS: I don't know why the download in the vim is blocked, however, in safari is pretty well (1.4m/s for me)
