Editing classpath file requires restart of VS Code #895
Description
Originally created by @vanessalange at microsoft/vscode-java-debug#576
When adding a jar to the classpath file the program won't build any longer and you get the error message: "Build failed, do you want to continue?" You have to restart VS Code before it works again.
Environment
- Operating System: macOS Mojave Version 10.14.4 (also Windows 10)
- JDK version: openjdk version "1.8.0_212"
- Visual Studio Code version: 1.33.1
- Java extension version: 0.43.0
- Java Debugger extension version: 0.17.0
Steps To Reproduce
- Create a new Java Project
- Add a jar to the classpath
- Try to run the program
Current Result
The build fails and you cannot run the program.
Expected Result
Either building works out of the box when editing the classpath or at least we get a message that restarting VS Code is required.
Additional Informations
The language server is loaded correctly (thumbs up icon).

@testforstephen can this be closed ? Doesn't
Update Project" handle this now ? For a Maven project, this seems to be working with"java.configuration.updateBuildConfiguration": "automatic"(though I believe the default isinteractive`). For an invisible project adding a jar to the library folder(s) also works.robstryker commentedon Nov 2, 2026
