error MSB6006: “cmd.exe” exited with code 2

问题

I had been compiling on my Visual Studio making small changes from the morning and it was running fine. I made a small change and I started getting this error,

error MSB6006: "cmd.exe" exited with code 2

I removed that small change I had done. The last change I had made was adding a line to a help text.

I have absolutely no clue what this means. Can somebody please help?

TIA
