In this article, we’ll learn how to configure Visual Studio Code with Java, and how to use its basic features for this language. Then, we’ll see the Maven and Gradle integrations and conclude with the strengths and the drawbacks of this editor.
Microsoft improved a lot the developer experience to configure their editor for Java. We can download the Coding Pack for Java, which is a set of essential extensions(the equivalent of JDT for Eclipse). Even if we haven’t installed anything yet, this executable package will check missing software and install them for us: 1. Visual Studio Code 2. Ja...
3.1. Create or Open a Java Project
If we want to create a new Java project, we’ll find theJava: Create Java Project command in the Command Palette menu, which opens a top menu where we can pick our project type: 1. No build tools creates a blank project with src and lib directories 2. Mavenlets us pick an archetype from a large library collection, as we’ll see in a later section 3. Spring Boot, Quarkus, and MicroProfile require that we install their respective extensions to create a project If we need to open an existing proje...
3.2. Run and Debug the Project
To run the project, we just have to press F5 (debug) or Ctrl-F5 (run). We can also use the Run|Debug shortcuts just above the mainmethods or the unit tests: We can also see the debug toolbar at the top of the window to stop, rerun, or continue execution. Then, the Terminalview at the bottom will show the output logs.
3.3. Manage Java Packages and Imports
The first pain point we’ll notice is that Visual Studio Code does not provide dedicated features to create a class or package. To create the whole directory structure of our package, we must first create a Java file and declare the required package at the top. After that, Visual Studio Code will show an error: we just have to roll over it to display the Quick Fixlink. This link will create the appropriate directory structure if it doesn’t exist. However, the package management works like in o...
4.1. Maven
If we choose to create a new Maven project, the Command Palette provides a large collection of Maven archetypes. Once we select one, we’re prompted to pick the destination folder, and then the configuration takes place in an interactive terminal, not in a graphical wizard, like in other Java IDEs. The Java import popup will be displayed first, then the Maven configuration will start. The extensions will use the global Maven client defined in our PATH variable. However, if the Maven Wrapperis...
4.2. Gradle
To work with Gradle, we must install the Gradle Extension Pack from the Extensions panel. This extension manages projects only if Gradle Wrapperis configured. After opening a Gradle project, we’ll see the status bar at the bottom indicating the download and installation progress. We check if any error occurred by clicking this bar. We can also display the Output view and choose Gradle Tasksoption from it. Then, we’ll be able to see the Gradle elephant icon in the sidebar, which displays dedic...
First, we have to admit that this lightweight editor offers fewer features than its counterparts: no wizard, Maven and Gradle integration is not very handy, and basic features are missing, such as tools to manage packages and dependencies. Visual Studio Code wasn’t designed for Java, and that’s something we can easily notice, especially if we’re fa...
In this article, we learned how to configure Visual Studio Code for Java, its supported features for this language, and saw its strengths and drawbacks. In conclusion, if we’re already familiar with Visual Studio Code, it can be a good editor to start learning Java. But if we’re already advanced Java IDE users and satisfied to work with them, we mi...
