I am really tired of struggling with Maven 2 all the time. Build tools should not be in the way. Recently I have been looking at Buildr and Gradle. Maven 3 seems to fix some of the struggles. So, what should I go for now? Buildr? Gradle? Or wait a year for Maven 3?

Gradle is between 7 and 85 times faster than Maven when building incremental changes; benefits increase with number of subprojects. Gradle builds are 3 to 30 times faster than Maven builds when task outputs can be resolved Gradle's build cache.
The publishToMavenLocal is a built-in task of the maven-publish plugin of Gradle, and it will not publish anything into the remote Artifactory (JCenter / Maven) at all. Make sure mavenLocal() is in the first position of the list. Make sure you are using the correct version of your library.
Gradle is based on a graph of task dependencies – in which tasks are the things that do the work – while Maven is based on a fixed and linear model of phases. With Maven, goals are attached to project phases, and goals serve a similar function to Gradle's tasks, being the “things that do the work.”
You can't use a Maven plugin as-is in Gradle; you'll have to port it to a Gradle plugin. How difficult this is depends on how many Maven APIs the plugin is using. Another strategy might be to call into Maven via Gradle's Exec task.
I wouldn't expect too much from Maven 3. The people behind the Maven pedigree of build tools have always held the assumption that project builds are homogeneous, that is: all build problems fundamentally boil down to the same problem. This view of the world can be held fairly consistently in the face of opposing views but comes at a cost. The absence of scripting logic in Maven ("when you want to script you know you're doing something wrong"), the cumbersome plugin API ("no ordinary Maven user should want to write a plugin") and the central repository ("we all have the same dependencies") are all testaments of this overarching assumption.
In the real world build problems are heterogeneous because people build software for a wide variety of reasons. They all 'develop' like we all 'drill holes' once in a while for solving unique problems. Regardless of your level of abstraction you'll always find similarities when comparing arbitrary build problems. It is the reveration of these similarities and the condemnation of differences that is the downfall for Maven's design and the reason why it draws so much flak. Basically, Maven is authoritarian and utopian in its outlook.
PS: Maven has good features, like convention-over-configuration and the idea of using repositories (the Maven implementation of this idea is troublesome).
