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 3.0.1.
FindBugs requires JRE (or JDK) 1.7.0 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 3.0.1, released on 13:05:33 EST, 06 March, 2015. We are very interested in getting feedback on how to improve FindBugs. File bug reports on our sourceforge bug tracker

FindBugs 2.0.3 is intended to be a minor bug fix release over FindBugs 2.0.2. Although than some improvements to existing bug detectors and analysis engines, and a few new bug patterns, and some important bug fixes to the Eclipse plugin, no significant changes should be observed. Consult the Change log for more details.

Here are various ways to run FindBugs. For plugins not supported by the FindBugs team, check to see what version of FindBugs they provide; it might take a little while for the plugins to update to FindBugs 2.0.
In 2009, Google held a global fixit for UMD's FindBugs tool a static analysis tool for finding coding mistakes in Java software. The focus of the fixit was to get feedback on the 4,000 highest confidence issues found by FindBugs at Google, and let Google engineers decide which issues, if any, needed fixing.
More than 700 engineers ran FindBugs from dozens of offices. More than 250 of them entered more than 8,000 reviews of the issues. A review is a classification of an issue as must-fix, should-fix, mostly-harmless, not-a-bug, and several other categories. More than 75% of the reviews classified issues as must fix, should fix or I will fix. Many of the scariest issues received more than 10 reviews each.
Engineers have already submitted changes that made more than 1,100 of the 3,800 issues go away. Engineers filed more than 1,700 bug reports, of which 600 have already been marked as fixed Work continues on addressing the issues raised by the fixit, and on supporting the integration of FindBugs into the software development process at Google.
The fixit at Google showcased new capabilities of FindBugs that provide a cloud computing / social networking backdrop. Reviews of issues are immediately persisted into a central store, where they can be seen by other developers, and FindBugs is integrated into the internal Google tools for filing and viewing bug reports and for viewing the version control history of source files. For the Fixit, FindBugs was configured in a mode where engineers could not see reviews from other engineers until they had entered their own; after the fixit, the configuration will be changed to a more open configuration where engineers can see reviews from others without having to provide their own review first. These capabilities have all been contributed to UMD's open source FindBugs tool, although a fair bit of engineering remains to prepare the capabilities for general release and make sure they can integrate into systems outside of Google. The new capabilities are expected to be ready for general release in Fall 2009.
The current development team consists of Bill Pugh and Andrey Loskutov.
The most recent funding for FindBugs comes from a Google Faculty Research Awards.
