Welcome to the update of Java on Visual Studio Code for November. In this update, we are excited to announce a new wizard for Java runtime configuration. Back to September, we published a blog<\/a> clarifying: 1) Java 11 as minimum version of JDK is only required for running VS Code for Java; 2) VS Code continuously supports projects with JDK version 1.5 or above. In that blog, we also shared how to configure JDKs for your project and for running VS Code for Java respectively, which requires you to manually configure two settings in \u2018settings.json\u2019 file. Although the manual approach works, we are aware that improvements in overall experience are still needed, which results in the implementation of Java Runtime Configuration Wizard.<\/p>\n

Java Runtime Configuration Wizard<\/h3>\n

Java runtime configuration wizard is part of Java Extension Pack<\/a>. Make sure you have the extension pack installed. As a side note, we strongly recommend installing the extension pack or Coding Pack for Java<\/a> for your Java development on VS Code. For details, please check here<\/a>.<\/p>\n

Load project into workspace<\/h4>\n

Click menu: Files<\/strong>->Open Folder\u2026<\/strong>\u00a0or Files<\/strong>->Open Workspace\u2026<\/strong> to load project into workspace. When you see a thumbs up icon \"Image<\/a> on status bar, your project is loaded.<\/p>\n

Open the wizard<\/h4>\n

Ctrl+Shift+P<\/strong> to launch command palette and then use command \u201cJava: Configure Java Runtime<\/strong>\u201d to launch the wizard.<\/p>\n

\"Image<\/a><\/p>\n

Configure project JDK<\/h4>\n

Project JDKs<\/strong> tab on the wizard configures JDK for project. When your project uses Maven or Gradle, WorkSpace Overview<\/strong> lists the language version set by the build tool; Maven\/Gradle Projects<\/strong> lists all eligible JDKs installed in your environment per the language version and also allows you to specify a JDK for your project.<\/p>\n

Configure JDK for running VS Code for Java<\/h4>\n

Java Tooling Runtime <\/strong>tab allows you to specify runtime to run VS Code\u2019s Java language tools, a.k.a. the Java Language Server. The tab only lists Java 11 or above JDKs installed in your environment, as required by the language server. Please, remember to reload VS Code to make change effective.<\/p>\n

\"Image<\/a><\/p>\n

Install JDK<\/h4>\n

Installed JDKs <\/strong>tab lists all JDKs in your environment found by the wizard.<\/p>\n

\"Image<\/a><\/p>\n

To facilitate installing new JDK when needed, Install A JDK<\/strong> section offers multiple options.<\/p>\n

Other Enhancements<\/h3>\n

Automatically infer selection range from cursor position<\/h4>\n

Language Support for Java(TM) by Red Hat<\/a> is able to infer selection range from cursor position now. As a result, expressions can be extracted and proposed by VS Code automatically for refactoring.<\/p>\n

\"Image<\/a><\/p>\n

Support exporting JAR through custom task<\/h4>\n

Project manager for Java now supports exporting JAR through custom task, which allows you to have fine-grained control on how JAR can be exported for your project.<\/p>\n

\"Image<\/a><\/p>\n

You can configure custom task by clicking menu: Terminal->Configure Tasks\u2026<\/strong> and then selecting the exporting JAR task for your project. You can run custom task by clicking menu: Terminal->Run Task\u2026<\/strong>, selecting Java,<\/strong> and then selecting the exporting JAR task.<\/p>\n

Try it out<\/h3>\n

Please don\u2019t hesitate to give it a try! Your feedback and suggestions are very important to us and will help shape our product in future.<\/p>\n
