Google is looking to one day replace Unify and build on all the functionality of Eclipse ADT and Ant build systems. Currently the company is working on a tool called "New Build System", pretty unique name right? The New Build System is still in very early stages of beta, in fact it just hit version 0.1 today, it's already looking to be very useful.
It seems as if you can build both dev and production versions of apps simultaneously, as well as the ability to utilize the same build process between Linux and ADT. Looks like this new project for Google is showing some potential already.
1. I wanted to use Eclipse to build 2 versions of the app - 1 dev and 1 production. There's no easy way to do that with ADT.
2. I wanted to use the same build procedure with ADT and Linux - same thing, no way.
The new build system looks like it'll solve these problems.
This new build system is built on gradle, which is "build automation evolved", and able to combine "the power and flexibility of Ant with the dependency management and conventions of Maven into a more effective way to build." Currently Google is encouraging any developers that are willing to try out the New Build System to send lots of feedback to them, so they can make it even better. The project is entirely done in AOSP, so in theory developers can grab the code and make their own contributions to the project. Now that's big!
You can get all the information from the source links below. If any developers out there do decide to try out this New Build System, be sure to leave your comments below.
