I have never been able to make hibernation (suspend to disk) work on my laptops (Dell M3800 and Dell XPS 13 9370) on Ubuntu with systemd. The symptom was that running

sudo systemctl hibernate |
was making the system shutdown, but then upon restart the system was not restored: it was just like booting the system from scratch. […]
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 […]
In this tutorial I’d like to show how to publish a Maven Site to GitHub Pages. You can find several documents on the web about this subject, but I decided to publish one myself because the documents I found refer to a deprecated plugin (https://github.com/github/maven-plugins/tree/master/github-site-plugin) or show complicated settings, also when using the official Maven […]
If you like to use KDE you probably install Kubuntu directly, instead of Ubuntu, which has been based on Gnome for a long time now. However, I like to have several Desktop Environments, and, now and then, I like to switch from Gnome to KDE and then back. Currently, I’m using Gnome for most of […]
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 tutorial I’m going to show how to install Linux on a USB drive using Virtualbox. I find this useful to test a LInux distribution. Note that using a live distribution only allows you a small testing experience, while installing Linux on a USB drive will give you the full experience (and if the […]
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 post is based on my Dell M3800 with Linux Neon. KDE already does a good job with touchpad gestures (e.g., two fingers for scrolling, 3 finger tap for pasting, etc.) but it does not support 3 finger swype gestures like in MacOs, e.g., for displaying all the windows or for showing the desktop. Today […]
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!
The second edition of the Xtext book should be published soon! In the meantime it is already available for preorders. At the time of writing, you can benefit for discounts and preorder it at 10$. I’ll detail the differences and novelties of this second edition. But, first things first! A huge thank you to Jan Köhnlein, for reviewing […]
HiDPI support in KDE Plasma has been recently improved! I’m afraid what’s not improved is the procedure for using that. In this post I’ll detail the steps to use HiDPI with KDE if you have a high resolution display (for example, I have that in my Linux Dell M3800). Remember that the settings you change […]
In a previous post I showed how to manage an Eclipse composite p2 repository and how to publish an Eclipse p2 composite repository on Sourceforge. In this post I’ll show a similar procedure to publish an Eclipse p2 composite repository on Bintray. The procedure is part of the Maven/Tycho build so that it is fully […]
After I upgraded my Dell Precision m3800 to the new Kubuntu Wily 15.10 I had a very bad surprise: the screen was continuously flickering in a way that it was unusable. This happens only if you are NOT using the default highest resolution 3200×1800 which, at least for me, is really too small. I thought it was […]
In this blog post I’ll describe my experience in preparing an Oomph setup for a non-trivial Xtext project, Xsemantics. This setup was kind of challenging because of the following features of my project, but I guess most of them can be found in any Xtext project: generated sources are not stored in the Git repository […]
The problem I was having when running SWTBot tests in Travis CI was that I could not use the new container-based infrastructure of Travis, which allows to cache things like the local maven repository. This was not possible since to run SWTBot tests you need a Window Manager (in Linux, you can use metacity), and […]
I’ve just started using the brand new Eclipse installer, and I’d like to report my experiences here. First of all, a big praise to Ed Merks and Eike Stepper for creating Oomph, on which the installer is based. 🙂 First of all, the installer is currently available in the “Developer Builds” section: Once you downloaded […]
