ot-clean, Zero maintenance overhead

The amount of time I can spend on open source project is limited. That is why maintainability is priority number one for me. If I want to add a new feature I want to focus on new feature only, no distractions. That is why one of the first things I have done was automation of entire project lifecycle. This includes building, high-coverage testing and single command release.


jcabi-parent is a parent pom from jcabi components which simplify getting up to date versions of popular dependencies. By updating version of parent pom, we can automatically update most of the libraries used in the project.


Qulice is Quality control instrument for Java projects. Very restrictive tool that preconfigures many code quality libraries like:

Maven-assembly-plugin + jar-with-dependencies

ot-clean is a command line tool. In order to prepare release I need to pack everything as a standalone jar file, add some execution scripts and pack everything together. I was looking for some easy way to do this and it turns out that those two plugins are handling this quite nicely.


Finally, when the project is ready I wanted to distribute it easily. This plugin is handling few steps:

Build & Release

In order to build and release my project I just need to execute two lines:

mvn clean install -Pqulice,cobertura
mvn github-release:release
