This page provides an overview of Liberty Tools for IntelliJ IDEA. For minimum requirements information and detailed instructions on how to use Liberty Tools, check the user-guide.
Liberty Tools for IntelliJ IDEA is an IntelliJ IDEA plugin for developing cloud-native Java applications with Open Liberty and WebSphere Liberty. Iterate fast with Liberty dev mode, code with assistance for MicroProfile and Jakarta EE APIs, and easily edit Liberty configuration files.
Liberty Tools for IntelliJ includes LSP4IJ, an external plugin dependency that is automatically installed with Liberty Tools. LSP4IJ is a free and open-source Language Server Protocol (LSP) client developed by Red Hat, enabling seamless language server integration.
If you wish to change the version of LSP4IJ installed along with Liberty Tools, you can refer to the documentation here.
Use Liberty Tools to run your Liberty Maven or Liberty Gradle projects through the Liberty tool window or the IntelliJ "Search Everywhere" window. You can start, stop, or interact with Liberty dev mode on all configured Liberty Maven and Liberty Gradle projects in your workspace. Liberty Tools also helps you quickly and easily edit your application and configuration files by providing language support features for MicroProfile, Jakarta EE, and Liberty configuration and Java files.
