Feature request from kanduvisla, posted on GitHub Dec 23, 2016 
 So I recently 'discovered' that you can set the proper urn's for your IDE with the command  bin/magento dev:urn:generate , but if you're running your Magento development environment in a VM (like I am) the paths generated do not match with the path on your development machine. 
 For example, in my VM, Magento 2 is installed in  /var/www/magento , and  /var/www  is mounted on my local directory  /Users/giel/PhpStormProjects/ProjectName . 
 So when I run  bin/magento dev:urn:generate ../misc.xml  it generates all mappings to  /var/www/magento  instead of  /Users/giel/PhpStormProjects/ProjectName , rendering this feature useless if you're running it in a VM. 
 So there are 2 options here: 
 
 I can edit  misc.xml  and find and replace all the paths. Or: 
 We can add an extra option to the CLI command,  --prefix  for example. 
 
 If we go for option 2, we can do something like: 
  bin/magento dev:urn:generate --prefix="/Users/giel/PhpStormProjects/ProjectName/" ../misc.xml  
 Would this be a nice attribution to this function? If so, I wouldn't mind spending some time creating it and sending a PR.
