Open Source Tools: Build – Travis & AppVeyor

Open Source projects have higher chances for success if their build instructions are clear and easily reproducible by anyone. It’s a very good idea to include a file that contains environment setup and clear build instructions to be followed. Even better would be to additionally configure a remote build mechanism that publicizes build status and results. This build mechanism can be used to Build and publish released binaries. Publish code coverage results and other quality gates. Build branches on demand, validating external contributions before merging (based on pull requests from GitHub for example). There are several options out there that Read More


Open Source Tools: Build – JitPack

Up until know we’ve discussed how to build projects using a couple of tools. Regardless of which one you pick you may need to deal with dependencies. The Java platform does not provide a specification for defining dependencies and their metadata and how to consume them, however the whole ecosystem has agreed on using JAR files as the binary packages and Apache Maven’s POM format as metadata. Often times you add a bit of configuration to your build file stating two things: the dependency coordinates used to locate the JAR file. the repository from where the metadata and the JAR Read More


Open Source Tools: Build – SDKMAN!

In the past two entries we’ve seen how to get started with Apache Maven and Gradle. You may have noticed that getting any of these tools installed on your system requires the following steps: Download a binary distribution (usually packaged as a ZIP file) from the official download page. Unzip the distribution anywhere on your system. Configure environment variables. Get ready to go! You must perform these steps every single time a new version comes out if you want to keep your toolbox up to date. There’s bound to be a better way to execute these repetitive tasks. This is Read More


Open Source Tools: Build – Gradle

Gradle is a JVM based build tool whose aim is to let developers create binaries from sources. It has grown in popularity in recent years due to is flexibility, one of the reasons why the Android ecosystem switched from Apache Ant to Gradle, turning every single Android developer out there into a Gradle user. Gradle has its origin way back in late 2007 as a response to Maven’s inability to deliver a flexible lifecycle. At the time Gradle’s aim was to deliver a richer model on which any kind of project could be built; this allowed Gradle to support non-JVM Read More


Open Source Tools: Build – Maven

Java projects need a way to produce binaries from sources. There are many tools out there that can achieve this goal, Apache Maven has been so far the most popular choice, chances are you have encountered in one way or another. Maven as we know it today is the result of a couple of iterations, starting with Maven 1 where the build was one step removed from its predecessor tool: Apache Ant. Maven 1 gave you a lot of freedom to define how a particular build should behave but forced developers to use XML in a programmatic way. This lead Read More


Java adventures in Japan

Three weeks ago I embarked on a 15 day trip to the land of the rising sun: Japan. The trip was a combination of some personal time and conferences. I must say that Kyoto was by far the most eye opening and awe inspiring place during this voyage. While visiting Fushimi Inari Taisha make sure to bring comfy shoes and water, walk the whole path around Mt. Inari, you won’t be disappointed. Granted there are other incredible places to visit in the country, very much looking forward to the next opportunity to discover those gems. The first stop in the Read More
