I hadn’t used Eclipse in Hyprland for a while. It used to work correctly; however, starting from somewhere in version 0.41, something broke, and it’s still broken in the current (at the time of writing) version 0.43. When I execute Eclipse in Hyprland, i.e., in Wayland mode, the trees in Eclipse, e.g., Package Explorer (but […]
The new release of Xtext 2.35.0 comes with many new cool features. I personally worked on the introduction of the JvmGenericTypeValidator. Quoting from the release notes: Automatic validation for Xbase languages The new JvmGenericTypeValidator was introduced to automatically perform several Java-related checks in the hierarchy of the inferred JvmGenericTypes of an Xbase language, with the corresponding error reporting. […]
This is a quick post about having nice fonts in Eclipse in Windows 11, based on my experience (maybe I had bad luck with the default configurations of Eclipse and/or Windows). When I bought my Acer Aspire Vero, I found Windows 11 installed, and now and then, I’m using Windows 11 (though I’m using Linux […]
TL; DR: Xtext sources are now in a single Git monorepo (https://github.com/eclipse/xtext), and the build infrastructure is based entirely on Maven/Tycho (Gradle is not used anymore). Background A few years ago, Xtext sources were split into 6 separate GitHub repositories. I did not take part in that decision (I guess at that time, I wasn’t […]
Although I’m a Linux user, I also recently bought a Mac Air M1, and I wanted to use Docker (a big part of my TDD book) to ensure that my projects based on Docker work on m1 as well. I then went to the Docker website for macOS and downloaded the version for the Apple m1 […]
UI tests are delicate since when you run them, you must not interact with the computer, or you will disturb the tests, which will likely fail. In Linux, you can use Xvfb, but windows will not have a title, which might break UI tests that rely on that. For example, Eclipse SWTBot tests work best […]
I want to share some benchmarks for building an Eclipse project with Maven/Tycho. I built the project on Linux, Windows, and macOS (in particular, on my Mac Air M1 2020). I stressed that the macOS environment is an M1, the new Arm-based chip from Apple, which is said to be quite efficient and performant. However, […]
Recently, I started to contribute and maintain Pitclipse, an Eclipse plugin for running mutation testing with PIT. We needed a mechanism to detect whether JUnit 5 is in the classpath of a Java project (so that we could run PIT with its JUnit 5 plugin). The first implementation of such a mechanism was rather cumbersome […]
If you update to Xtext 2.27.0 and have compiler tests for your Xbase DSL that assert the output of the compilation, you’ll get lots of failures after the update. I am guilty of that 😉 Well, for a good reason, at least 🙂 In fact, I worked on this issue: https://github.com/eclipse/xtext-extras/issues/772 and its fix is […]
I had previously written about mirroring Eclipse p2 repositories (see this blog tag), but I’ll show how to do that with Tycho and one of its plugins in this post. The goal is always the same: speed up my Maven/Tycho builds that depend on target platforms and insulate me from external servers. The source code […]
Say you publish a p2 repository for your Eclipse bundles and features. Typically your bundles and features will depend on something external (other Eclipse bundles and features). The users of your p2 repository will have to also use the p2 repositories of the dependencies of your software otherwise they won’t be able to install your […]
I had already described the process of publishing an Eclipse p2 composite update site: Publish an Eclipse p2 composite repository on Bintray Publish an Eclipse p2 repository on Sourceforge with rsync Well, now that Bintray is shutting down, and Sourceforge is quite slow in serving an Eclipse update site, I decided to publish my Eclipse […]
Before releasing Maven artifacts, you remove the -SNAPSHOT from your POMs. If you develop Eclipse projects and build with Maven and Tycho, you have to keep the versions in the POMs and the versions in MANIFEST, feature.xml and other Eclipse project artifacts consistent. Typically when you release an Eclipse p2 site, you don’t remove the […]
I haven’t been blogging for some time now. I’m getting back to blogging by announcing my new book on TDD (Test-Driven Development), Build Automation and Continuous Integration. The title is indeed, “Test-Driven Development, Build Automation, Continuous Integration (with Java, Eclipse and friends)” and can be bought from https://leanpub.com/tdd-buildautomation-ci. The main goal of the book is […]
In this small blog post I’ll show how Eclipse looks like in Linux Gnome (Ubuntu 17.10) with a few Gnome themes. First of all, the default Ubuntu theme, Ambiance, makes Eclipse look not very nice… see the icons, which are “packed” and “compressed” in the toolbar, not to mention the cut “Filter Files” textbox in […]
In this tutorial I’m going to show how to analyze multiple Eclipse plug-in projects with Sonarqube. In particular, I’m going to focus on peculiarities that have to be taken care of due to the standard way Sonarqube analyzes sources and to the structure of typical Eclipse plug-in projects (concerning tests and code coverage). The code […]
Especially with lambdas, you may end up with a chain of method calls that you’d like to have automatically formatted with each invocation on each line (maybe except for the very first invocation). You can configure the Eclipse Java formatter with that respect; you just need to reach the right option (the “Force split” is […]
In this post I’ll show how to add an Eclipse launcher as a favorite (pinned) application in the Gnome dock (I’m using Ubuntu Artful). This post is inspired by http://blog.ttoine.net/en/2016/06/30/how-to-add-eclipse-neon-launcher-in-gnu-linux-menus-and-launchers/. First of all, you need to create a .desktop file, where you need to specify the full path of your Eclipse installation:

This is relative […]
In this tutorial I’ll show how to use Jacoco with Maven/Tycho to create a code coverage report of multiple Eclipse plug-in projects. The code of the example is available here: https://github.com/LorenzoBettini/tycho-multiproject-jacoco-report-example. This is the structure of the projects: Each project’s code is tested in a specific .tests project. The code consists of simple Java classes doing […]
The second edition of the Xtext book, Implementing Domain-Specific Languages with Xtext and Xtend, was published at the end of August: https://www.packtpub.com/web-development/implementing-domain-specific-languages-xtext-and-xtend-second-edition. So… get it while it’s hot 🙂 Please, see my previous post for details about the novelties in this edition. Sources of the examples are on github: https://github.com/LorenzoBettini/packtpub-xtext-book-2nd-examples. Hope you’ll enjoy the book!
