Customer is running a java maven application internally but any command they execute like build, run , test by clicking the task on the right they are getting this error.
 
Error launching task 'build': Request runTask failed with message: Failed to execute Che command: Protocol "http:" not supported. Expected "https:"
 
But when they run maven clean install from terminal it works.  Googling this is the closest link I can find but it is not the exact same scenario.
