The following Ant-build sample runs the five tools Findbugs, Checkstyle, PMD, JUnit and Cobertura. Ant-builds have the big advantage over Maven-builds that you have everything under control and a minimal foot print of the build result. This justifies the overhead of writing the build.xml file. The sometimes huge number of non needed libraries and difficult control of the used libraries is the main reason why I don't like Maven for real projects. Maven is better than Ant for quick hacks.
