The Build Tool Report: Turnaround Times using Ant, Maven, Eclipse, IntelliJ, and NetBeans

Some time ago we ran a survey asking a few questions about the build process, specifically the tools that are used to do incremental builds and how much time those builds take. We had over 600 responses, so now it’s time to count the results.

This is the first time that we’ve published results on the incremental build process, so the information is more likely to serve as a guide than an authoritative information source. That being said, the information is still quite interesting, and if it serves to start a conversation that improves the process of even one team, then we’re proud to have helped out. If you haven’t answered the 3-question survey yet, take two minutes and go for it – and do let your community know about it – as more answers trickle in we’ll update this post with the new data. If you’d like to play with the results on your own we‘ve provided all the data and our calculations in a handy Excel sheet that you can download here.

Survey Results: The Java EE Container Redeploy & Restart Report – measuring Turnaround Time

Since we’ve had more time to analyze them we also hope to provide a few insights into the data including a more detailed container breakdown.

JavaRebel 2.0.2b or ‘no plan survives contact with the enemy’

When we released 2.0.2 we had put it through every test suite in our arsenal to ensure that it would thrive and grow up strong (especially after a month of testing in the nightly builds). As the gods would have it, reports started coming in that not everything was as blissful as we like it with the Spring plugin, so we quickly fixed it up and released 2.0.2a. Now, a week later, we’ve released a followup release — 2.0.2b.

DNArebel — Improve Yourself, Today

We at ZeroTurnaround believe that all bugs must be corrected as soon as possible. However often it just doesn’t seem possible to do that immediately (if ever). Usually in such cases the bugs are not so much in the code of the program as in the DNA of the engineer.
