Crowd-In CLI hangs when trying to report an error

Crowd-In hangs when trying to report an error If the crowd-in CLI cannot find translation files when trying to upload translations and encounters an error, the threads of the CLI block each other because they are all trying to print output and the CLI process hangs

To Reproduce Steps to reproduce the behavior:

1. Start crowdin cli sync with it expecting a file say bundle_hi_IN.properties which does not exist
2. Crowdin CLI hangs

Expected behavior Crowdin CLI exits with an error

Environment:

• python:3.7-stretch docker image

Additional context Here is a threaddump illustrating the deadlock

@andrii-bodnar sorry for the radio silence - it looks like this has been cleared up now through a combination of better stderr handling / updating the cli version! thanks!

i looked a little further into the heap dump of the JVM and found that multiple threads are somehow running into FileNotFound exceptions for different files - and they then seem to block each other. i’m also not sure why the files are not getting these errors as the files seem to be there on the file system
