Hi everyone, welcome to the our June update for Visual Studio Code for Java!
In this article, we’re going to provide you an update about our code completion performance improvement, user experience enhancements in both unit testing and project creation, so let’s get started!
Code Completion Performance Improvement
Faster code completion is a crucial aspect of any developer tool that can greatly enhance coding productivity. In the past, we have heard from our users they felt Java code completion was slow sometimes which has impacted their work. As a result, we have been researching into how to make it faster and as a result, we have actually made significant progress.
We will write a detailed blog later highlighting the technical details but here is some preliminary result between version 1.16 (2023-03) and version 1.19 pre-release (2023-05)
Latency reduction (compared to 1.16)
1.19 pre-release (2023-05-19)
We hope the code completion performance improvement can bring you better coding experience and we will continue to enhance the performance, reliability and compatibility of the Java language support in Visual Studio Code Java. In the next few months we will roll out a series of performance updates, please stay tuned!
Support postDebugTask in Test Runner for Java
In latest release of Test Runner for Java (part of Extension Pack for Java), we have added the support for attribute postDebugTask. This attribute will launch a task at the very end of a debug session. This will be very useful if developer needs to perform some cleanup task after the unit testing is done. For example, cleaning up databases. You can configure the task in the following way:
Notice that these are just examples and you can configure the tasks the way whichever way you prefer.
Here’s a demo:

New Project Types in Project Manager
Thanks to contribution from the community (PR #765 and PR#757). Project Manager for Java now supports creating Micronaut and Graal Cloud Native Projects, you can now create those projects from the command palette (Java: Create Java Project) or just using “Create Java Project” button on the UI. Here’s a demo. Notice: you will need to install the corresponding extensions for these to work.
Install Extension Pack for Java
To use all features mentioned above, please download and install Extension Pack for Java on Visual Studio Code.
If you are a Spring developer working on a Spring Boot application, you can also download the Spring Boot Extension Pack for specialized Spring experience.
