Liking Gradle

Last week I have spend a lot of time getting Maven 2 the way I wanted. In most cases Maven is doable, but in case Multiverse, I have some very specific requirements. I need to run the same tests again using different configurations (javaagent vs static instrumentation) and I also need to fabricate a very special jar that integrates all dependent libraries (using jarjar) and does some pre-compilation.

The big problem with Maven is that defining complex builds using the plug-in system is not that great. I have spend a lot of time on configuring the plugins because they were not working like expected or not working at all.

A long time ago I took a look at Gant, but ANT (even if you do it in groovy) still is ANT; meaning a lot of manual labor. So I wanted to give Gradle a try; the power of Groovy combined with a plugin system and predefined build system from Maven. And after 1 day of playing with the scripts, I have got most stuff up and running exactly like the current Maven system (even the artifacts being deployed to the local maven repository!). And I guess that during this week I can make the switch final.

One of the things I really need to get started on, is creating an elaborate set of benchmarks. Using Maven it is fighting the framework, but with the complete freedom you have in Gradle, but still all the facilities provided by plugins, it think it is going to a joy to begin with.

We’ll see what Maven 3 is going to bring, but I’m glad that there is a usable alternative available.
