Continuous Integration

Build tools

Building a software consists of various steps, often including:

compiling computer source code into binary code,
packaging binary code,
running automated tests,
deploying to production systems,
creating documentation and/or release notes.

As building a large software product is a complex task, all popular programming languages have build automation tools. One of the most well-known build tools is GNU Make, a flexible application primarily used for compiling C/C++ code. (However, Make is flexible enough for building any source code, including LaTeX documents.)

Maven

During the course, we will use Gradle, a build automation tool.

Maven embraces the paradigm of convention over configuration, which means that typical build processes can be defined with a small amount of code.

Learning resources

For learning the advanced features of Maven, there is an excellent book titled Maven by Example.

If you wish to build Eclipse plug-ins, use the Tycho Maven plug-in. We compiled some guidelines in our Maven and Eclipse cheat sheet.

Alternatives

Gradle's main competitors are Apache Ant, Apache Maven and SBT. Building a simple project is quite straightforward with all modern build tools, but for more complicated, you have to factor a lot of requirements: support for different languages (Scala, Kotlin, Xtend), platforms (OSGi), IDE integration and so on.
