LSP-jdtls

This is a helper package that manages and downloads the Eclipse JDT language server for you.

To use this package, you must have:

• The LSP package.
• A Java SDK (>= 21).
• It's recommended to have JAVA_HOME defined in your environment variables. Otherwise, specify java.home in the plugin settings.

Configuration

Configure jdtls by running Preferences: LSP-jdtls Settings from the command palette.

Capabilities

jdtls can do a lot of cool things, like

• code completion
• signature help
• hover info
• code actions
• formatting
• find references
• goto def

Commands

Troubleshoot

Server exits with code 13

The server caches workspace specific information in a data directory that is separate for each workspace (Sublime project or set of open folders). When this data is corrupted the server crashes with exit code 13 and the server is disabled for the current project.

Run the command LSP-jdtls: Clear data from the command palette and re-enable the server using the command LSP: Enable Language Server in Project.

Running tests fails with "LSP-jdtls must be installed via package control"

The Java adapter of Debugger only starts when both LSP and LSP-jdtls are installed via Package Control. If you installed either of them manually (e.g. cloned or symlinked into the Packages folder), list it in installed_packages in the Debugger settings (Preferences: Debugger Settings from the command palette):

{
    "installed_packages": ["LSP", "LSP-jdtls"],
}
