Visual Studio Code! This FAQ will hopefully answer some of the questions you may have.</p> <h2 id="_are-these-java-extensions-open-source" data-needslink="_are-these-java-extensions-open-source">Are these Java extensions open source?</h2> <p>Yes. All the <a href="/docs/java/extensions">Java Extensions</a> provided by Red Hat, Microsoft, and VMware are open source, as well as most extensions supported by the community. You can find their corresponding repositories on GitHub from the Marketplace pages.</p> <h2 id="_are-there-any-other-features-coming-to-java-on-visual-studio-code" data-needslink="_are-there-any-other-features-coming-to-java-on-visual-studio-code">Are there any other features coming to Java on Visual Studio Code?</h2> <p>Definitely. We use GitHub issues to track incoming requests and planned work for each of our extensions. Currently we're working on adding more refactoring and linting features to enhance the editing productivity, as well as some performance improvements to make it even faster.</p> <p>Most of our work is collected from and prioritized by customer feedback. If you're interested in providing your thoughts, you can go directly to our project repositories to submit a new issue to share your thoughts.</p> <p>We do have limited capacity within the team and we'd really like to encourage more contributions from the great Java community. If you're passionate about your idea and would like to help fellow Java developers, you're welcome to join us! Some areas worth considering including Gradle support, code analysis and test coverage tools, profiler, and additional framework support including DropWizard, JavaFX, JPA, Play, Akka, OSGi.</p> <h2 id="_can-i-use-keyboard-shortcuts-from-other-ide" data-needslink="_can-i-use-keyboard-shortcuts-from-other-ide">Can I use keyboard shortcuts from other IDE?</h2> <p>Sure. <a href="/docs/editor/keybindings#_keymap-extensions">Keymap extensions</a> in VS Code modify the VS Code shortcuts to match those of other editors. You can find <a href="https://marketplace.visualstudio.com/items?itemName=k--kato.intellij-idea-keybindings" class="external-link" target="_blank">IntelliJ IDEA keyboard shortcuts</a>, <a href="https://marketplace.visualstudio.com/items?itemName=alphabotsec.vscode-eclipse-keybindings" class="external-link" target="_blank">Eclipse Keymap</a> as well as keymaps for other popular editors in <a href="https://marketplace.visualstudio.com/search?target=VSCode&category=Keymaps&sortBy=Installs" class="external-link" target="_blank">Keymaps category</a> of extensions in the Marketplace.</p> <h2 id="_where-can-i-find-the-latest-progress-of-java-support-on-visual-studio-code" data-needslink="_where-can-i-find-the-latest-progress-of-java-support-on-visual-studio-code">Where can I find the latest progress of Java support on Visual Studio Code?</h2> <p>You can follow us on the <a href="https://devblogs.microsoft.com/java/" class="external-link" target="_blank">Java at Microsoft</a> blog, which will keep you updated on our progress.</p> <p>While you're using Java within VS Code, you may also see a <strong>Release Notes</strong> section after you update the <a href="https://marketplace.visualstudio.com/items?itemName=vscjava.vscode-java-pack" class="external-link" target="_blank">Extension Pack for Java</a>. The notes will give you an overview on the notable updates included in the extensions.</p> <h2 id="_how-can-i-use-visual-studio-code-with-new-java-versions" data-needslink="_how-can-i-use-visual-studio-code-with-new-java-versions">How can I use Visual Studio Code with new Java versions?</h2> <p>Thanks to the upstream update from JDT, you can now build your project up to Java 22 with VS Code as well.
