Generic Trend or preferred mode of developing plugins

Hi All,

What is the generic trend of plugin development for NetBeans, do you prefer
creating a Maven based plugin or still working on Ant based plugin for
netbeans.

I am asking with the consideration that a plugin developer has to
1) Keep the plugin on Github and may want to use the TravisCI type of build
some day
2) Have to submit the plugin to the Plugin portal for verification by
signing it
3) Maintain the plugin for all the upcoming versions of the NetBeans IDE
Platform.

with regards
Tushar
