Hi Srinath, As of my observations, whenever something is reported as a WARNING by maven, it takes some time, as warning indicates a bad practice. For example, when the start-up warnings were fixed, we noticed an improvement in the build.
Similarly, I feel, if we fix the issues that are reported in the middle of the build, that will further improve the build time. Just taking two examples. 1) Invalid POMs. [1]. 2) No matching referrals [2]. By fixing these warnings at component levels, we can improve the build-time further. Though, as a whole it looks a considerable effort, if we take care of our own components, it should be an-easy-to fix to make the build WARNING-free. I will look more into this.
