Code Quality with Eclipse Plugins

Tech leads are continually challenged with identifying and governing code quality. The common response is to look to test coverage as a measure of quality. Previously I was challenged to monitor code and architectural quality for over 50 developers both on and offshore. The shear amount of code made manual reviews a nightmare. While had reports on coverage it became apparent that the quality of the tests themselves  was also in question. It was time for a more automated review of quality.

After reviewing a series of tools and working through various industry best practices, here is the list of tools I ended up relying on regularly.

Automatically Format on Save

• FormatOnSave (http://ejp.sourceforge.net/formatonsave/update/)

The standard fare

• PMD (http://pmd.sf.net/eclipse/)
• Checkstyle (http://eclipse-cs.sourceforge.net/update)

Often Overlooked

• Find Bugs (http://findbugs.cs.umd.edu/eclipse)
• Enerjy (http://update.enerjy.com/eclipse)

Code Coverage

• Coverclipse (http://coverlipse.sourceforge.net/update)
• EclEmma (http://update.eclemma.org)

Focus on the important code

• JDepend (http://andrei.gmxhome.de/eclipse/)
• Metrics Plugin (http://metrics.sourceforge.net/update)

There are a few really good articles to help you get up and running with these
