FindBugs

Work in progress

As an alternative to FindBugs, it can be easier and more powerful to use Sonar for more code quality analysis. Sonar provides FindBugs reports.

FindBugs is installed on the build server:

• /shared/common/findbugs-1.3.9/

Using FindBugs from Ant

An example of running FindBugs from Sapphire build.

ant findbugs -Dfindbugs.location=/shared/common/findbugs-1.3.9/
