Maven Dependencies Pop Quiz – Results

A couple of weeks ago I posted a link to a pop quiz regarding dependency resolution in Apache Maven. 509 brave souls took the challenge; now is the time to share the results. The quiz is comprised of 14 questions split between 3 sections based on context: A single project A project with a parent POM A project with a BOM Each question revolves around figuring out what would be the selected version of a particular dependency, in this case Guava, because as many developers know, whenever there’s a classpath issue Guava is always to blame (What?!) To be fair, Read More


Configuring the OCI Gradle Build Cache plugin with GitHub Actions

Following up on the previous post that explains how to setup the OCI Gradle Build Cache plugin on Travis-CI today I’d like to show how to do the same with GitHub Actions. The steps to follow are quite similar; if you do not already have an OCI account and/or a configured compartment then please follow steps 1, 2, and 3 as explained in this post, then proceed with the next steps Step 4: Apply the plugin to your project Paste the following into your settings.gradle file Notice that the location of the config file is local to the project. There’s Read More


Configuring the OCI Gradle Build Cache plugin with Travis-ci

The following post describes how to configure the oci-gradle-build-cache plugin to write to the cache when running on Travis-ci. I’m assuming dear reader that you have an Oracle Cloud account ready, but if that were not to be the case then you can sign up for an Always Free tier account at https://www.oracle.com/cloud/free/. Let’s get started! Step 1: Create a config file There are a couple of ways to configure the plugin, we’ll use a configuration file whose format is specified at this page; you must gather the following information from your account tenancy id user id default home region Read More


Running Gradle inside Maven

As organizations evolve so do their codebases. Apache Maven and Gradle are the most popular and widely used build tools in the JVM. Usually multi-project builds rely on a single build tool to accomplish the job but there may be uses cases where you need to combine both, having Maven be the one leading the pack. One possible use case is to build a companion Gradle plugin, this is the case for ByteBuddy and Quarkus; another use case is to run a composite build with Maven and Gradle projects mixed together. In this post I’ll show how Gradle can be Read More


Hack.Commit.Push Paris 2019

I’m so excited to share what happened at Hack.Commit.Push Paris 2019. It’s said that an image speaks louder than words, so here it is Success! The event transcurred as follows as far as I remember (we event organizers participated in the hacks too thus we ended up jumping from one place to the next, fun!). We arrived in the morning to help setup the venue and get ready for registration, just to find out that Florent, Dilek, Hervé, and Michael had made the necessary preparations already, there were so eager to get started that they beat us to the punch.

Composite builds with Maven and Gradle

Gradle offers a neat feature called “Composite Builds” which allows one project to consume artifacts from other builds as if they were part of a single coherent unit. This feature is pretty easy to setup, however you might not know that it’s possible to do the same with Maven. Here’s how. Let’s say you have a producer and consumer projects, where producer is set as a dependency on consumer. If these two projects are to have their own release lifecycles their file structure may look like this The contents of the Gradle build files look like so And in the Read More


Announcing oci-gradle-plugin version 0.1.0

The first release of the OCI Gradle Plugin is out! The plugin lets you interact with the Oracle Cloud Infrastructure Java SDK. The behavior provided by OCI Java SDK is quite extensive, thus for this release the plugin delivers the minimal features required to setup and work with instances. Here’s an example, the following command will setup an Instance in a particular Compartment, while at the same time setting up a new VCN, Subnets, an InternetGateway and an InstanceConsoleConnection, allowing you to SSH to the freshly created instance $ ./gradlew setupInstance \ –compartment-id=ocid1.compartment.oc1…noa \ –instance-name=test \ –image=Oracle-Linux-7.6-2019.04.18-0 \ –shape=VM.Standard2.1 \ Read More


Hack.Commit.Push

Last month I twitted a rather cryptic message Hack — Andres Almiray (@aalmiray) March 1, 2019 Commit — Andres Almiray (@aalmiray) March 2, 2019 Push — Andres Almiray (@aalmiray) March 2, 2019 Followed by another one hack.commit.push — Andres Almiray (@aalmiray) March 8, 2019 Today I’m happy to announce the meaning behind these messages: http://hack-commit-pu.sh, the first ever, full day Hackergarten conference is open! If you have attended a Hackergarten before then you know what to expect, if not then let me say a few words about Hackergarten. The group was born in Basel, Switzerland back in 2010. The point Read More


New features in Kordamp Gradle plugins

Version 0.14.0 of the Kordamp Gradle plugin suite is ready! This release brings a host of updates that should make your life easier when looking for gaining insights into your build. To begin with, all reporting tasks provided by the org.kordamp.gradle.base plugin will use ANSI colors if the terminal supports them. This make its easier to determine a particular setting, here’s for example the settings for the info and test (new) sections found in the alibaba/Sentinel project: The color code is as follows white: property names yellow: string literals cyan: numbers green: boolean, when true red: boolean, when false Speaking Read More


Building ThinWARs with Gradle

UPDATE: As it turns out the two POM files (javaee-api 8.0) (microprofile 1.3) consumed by the build files shown here are not real BOMs. A POM is considered a BOM if it defines a <dependencyManagement> block which neither of these files do. They are just regular POM files for which the regular dependency resolution mechanism works out of the box. This means there’s no strict requirement for building ThinWARs with Gradle 5.0, you can use earlier versions too. The Gradle build file has been updated to reflect this change however the screencast remains unchanged. Java Champion Adam Bien has advocated Read More
