The goal of quality-check is to provide a small Java library for basic runtime code quality checks. It provides similar features to org.springframework.util.Assert or com.google.common.base.Preconditions without the need to include big libraries or frameworks such as Spring or Guava. The package quality-check tries to replace these libraries and provide all the basic code quality checks you need. The checks provided here are typically used to validate method parameters and detect errors during runtime. To ...

Clirr is a tool that checks Java libraries for binary compatibility with older releases. Basically you give it two sets of jar files and Clirr dumps out a list of changes in the public api. Clirr provides an Ant task that can be configured to break the build if it detects incompatible api changes. In a continuous integration process Clirr can automatically prevent accidental introduction of binary compatibility problems in Java libraries.
