There is a pattern that I use for pushing mercurial changes to other SCMs (eg. subversion) that I will describe in another post. I intend to use <a href=\"http:\/\/ant.apache.org\/ivy\">Ivy<\/a> for my dependency management, so I install <a href=\"http:\/\/www.apache.org\/dist\/ant\/ivyde\/updatesite\">IvyDE<\/a>. I then install the code quality plugins that John mentions, as well as the Metrics plugin.

This is a new plugin from Kent Beck that runs your unit tests after every save. It&#8217;s currently on paid beta, and I highly recommend it. <a href=\"http:\/\/junitmax.org\/junitmax\/subscribe.html\">Subscribe here<\/a>, it&#8217;s only $2\/month <\/p>\n<p \/>\n<h2>Templates<\/h2>\n<p>I update the following templates in Java -&gt; Code Style -&gt; Code Templates <\/p>\n<p><strong><span style=\"text-decoration:underline;\">Method Body<\/span><\/strong><\/p>\n<pre class=\"prettyprint\">\r\n\/\/ ${todo} Auto-generated method stub\r\n${body_statement}\r\n<\/pre>\n<p>This evaluates to an empty (apart from the comment) method for void types, or <code class=\"prettyprint\">return null;<\/code>. I&#8217;ve already discussed <a href=\"http:\/\/andypalmer.com\/2008\/08\/returning-null-considered-dishonest\/\/\">my thoughts on returning null<\/a>, and I would rather my code failed if it hits an <abbr title=\"sometimes I get carried away and forget to implement things :-D\">unimplemented method<\/abbr> rather than continue in a potentially unsafe manner.
