The Maven-Grester plugin is a Maven2 plugin for Jester, the JUnit tester tool. It enables Jester to be executed at any valid Maven lifecycle phase in a Maven Project. It saves developers from constructing cumbersome Java classpath entries on the commandline every time they need Jester to run against JUnit Tests in the project. It can also help to dispense with a suite of scripts that may have been written to handle complex Java classpath executions for Maven projects.
Gnasher alleviates developers from having to execute maven builds with the "-o" option (offline) to avoid accessing external repositories' metadata files. The SHA1 hash files and the missing pom metadata files for dependencies are created if they are missing. The next time the build is run, external repositories are not accessed and the build runs faster.
GreenMail is a suite of email servers for testing purposes and sandbox development. It supports SMTP, POP3, and IMAP (including SSL) and can be embedded into any Java application or unit test. The GreenMail Service (SAR) extension runs as a JBoss embedded developer mail server sandbox, manageable via JMX.
Kundo provides a structured, convention based approach for Java builds. Kundo has a pluggable, extensible architecture; it harnesses the power and flexibility of Groovy and Ant to provide a highly configurable Java build framework. Kundo achieves this flexibility with a plug-in architecture that attaches behaviors (provided by Kundo plug-ins) to build lifecycle phases. Kundo consists of a kernel and a set of foundation plug-ins. The kernel is responsible for the orchestration of the multiple collaborators within the build system.
