FindBugs™ - Find Bugs in Java Programs

This is the web page for FindBugs, a program which uses static analysis to look for bugs in Java code.  It is free software, distributed under the terms of the Lesser GNU Public License. The name FindBugs™ and the FindBugs logo are trademarked by The University of Maryland. FindBugs has been downloaded more than a million times.

The current version of FindBugs is 2.0.1.

FindBugs requires JRE (or JDK) 1.5.0 or later to run.  However, it can analyze programs compiled for any version of Java, from 1.0 to 1.8. The current version of FindBugs is 2.0.1, released on 20:25:22 EDT, 12 July, 2012. We are very interested in getting feedback on how to improve FindBugs.

FindBugs 2.0 Release

After many delays, we have released FindBugs 2.0. We are pretty happy and confident about the functionality, although we know the documentation of the changes in 2.0 is lacking. We decided that releasing 2.0 took precedence over fixing the documentation. Anyone currently using FindBugs 1.3.9 should find FindBugs 2.0 to largely be a drop-in replacement that offers better accuracy and performance.

Also check out http://code.google.com/p/findbugs/w/list for more information about some recent features/changes in FindBugs.

Major changes in FindBugs 2.0

• FindBugs Communal cloud
• checks for updated versions of FindBugs
• Powerful plugin capabilities
• new bug patterns, including new/improved support for Guava and JSR-305
• improved performance
