I've just started using the new(ish) eclipse-tapestry5-plugin and I must say it's great!!
The killer feature for me is the '+' button to create a .tml, .css, .js file from a java class in a maven friendly location pre-filled with useful templates. Kudos to Dmitry Gusev for a great plugin. If you haven't tried it yet... go get it!! https://github.com/anjlab/eclipse-tapestry5-plugin
