Java on Visual Studio Code – May Update

June 20, 2022

Hi everyone, welcome to the May update of Visual Studio Code Java.

In this month’s update, we are going to share exciting improvements to our user experience regarding signature help and code completion as well as new Gradle features.

Let’s get started!

Signature Help Improvement

Signature Help displays the signature of a method in a tooltip when a user types the parameter list start character (typically an opening parenthesis). In our latest release, we have made some major improvements to this feature:

  • We added the capability so that the signature help can be triggered automatically
  • We also added two settings to control 1) whether the signature help needs to triggered automatically 2) whether the detailed method description needs to show automatically (this means both the signature and detailed documentation of the method will be displayed)

Here is a demonstration of this feature

The settings to control how you would like to customize the signature help behavior can be found in the following screenshot:

Control Insert / Replace Mode for Code Completion

In Visual Studio Code, when you accept a code completion suggestion, you can either overwrite or insert. This behavior can be changed in the “Editor > Suggest: Insert Mode” setting.

However, in the past, this feature might not work for Java code as it requires LSP to adopt it.

In our latest release, we have made some changes so now it fully works with our Java extensions. In addition, you can use Shift key to switch between two modes on the fly!

The setting to set this preference can be found here:

Insert replace code completion

We hope these user experience improvements can really help to speed up your coding productivity!

Gradle Improvements

As we shared in our roadmap previously, build tools is one of our major focuses. We are glad to share that in this area we are working very closely with Gradle Enterprise to improve our Gradle for Java extension.

In May, we have a few things to highlight:

Pin Favorite Task

When working with Gradle projects, it is quite common for a developer to repeatedly run some tasks. To save developers time, we have now provided a feature that allows you to “pin” a task at the top of the project view so that it’s easy to find the task and run it again. You can even pass it with an argument. Here is a demo of this feature.

Bug fixes – Support Multi-level Projects and Chinese Encoding Issue

An issue was reported from the community that when our extension searches for a task in a multi-level project, it will duplicate the task indefinitely. This is because of the incorrect usage of a Gradle API call. We have fixed this issue in our latest release.

Another issue that would cause garbled Chinese characters was also fixed. Both issues were reported from the GitHub, and we thank the community for finding them and providing the sample projects with repro steps. Please continue sharing feedback with us.

Feedback and suggestions

As always, your feedback and suggestions are very important to us and will help shape our product in future. There are several ways to give us feedback
