In fact, the IDE is also the bottom of the call command-line tools, but to ordinary developers to present a more friendly development interface. This is not to let everyone give up the IDE to change the command line, but every thing has his reason for existence, whether it is a programming language or tools are a principle of "no best, only the most suitable."</span></p></p><p><p><span style="font-size: 15px; font-family: arial, helvetica, sans-serif;">A period of time to do a person product, release products in order to count the flow of all channels to build a channel package, you know hundreds of domestic channels, by the IDE compiled packaging non-vomiting.
