Multiple Unsupported Activation Events and Plugin Loading Errors in Theia 1.52.0 on Windows 11

[wenhaofan]

Bug Description:

During the setup of Theia using the provided steps and version, multiple errors related to unsupported activation events and plugin loading issues were encountered, leading to the inability to properly start Theia with the custom configuration.

Steps to Reproduce:

1. Follow the installation and build instructions from the Theia documentation: https://theia-ide.org/docs/composing_applications
2. Run the commands:
   • yarn
   • yarn theia build
   • yarn start
3. Observe the errors in the console log during the startup process.

Expected Behavior:

Theia should start without errors and all plugins should load successfully without causing activation event or provider registration conflicts.

Actual Behavior:

Multiple errors are thrown related to unsupported activation events and problems with registering file system providers, leading to a failed startup or improper functioning of Theia.

The C# toolkit on Windows 10 systems doesn't work in Theia either.

The C# toolkit on Windows 10 systems doesn't work in Theia either.Windows 10 系统上的 C# 工具包在 Theia 中也无法使用。

Hey, I haven't experienced that issue. Have you tried running Python and the debugger plugin locally?

[tsmaeder]

@wenhaofan I can confirm that there are a bunch of unsupported activation events with the Theia built-ins. Unfortunately, the documentation on the VS Code side is woefully out of date (https://code.visualstudio.com/api/references/activation-events).
I cannot confirm any of the file system provider-related issues, though. What is your application configuration (i.e. which Theia extensions do you include") and what plugins (aka VS Code extensions) at what version level do you have installed?

This configuration matches the official documentation and there are no differences from the recommended setup.

I think Python, Web, and a bunch of other extensions are not working properly...

[tsmaeder]

@wenhaofan two things I can see immediately:

1. You are using the 1.50.1 version of the built-in extension pack. The extensions pack version correspond to VS Code version, not the Theia version, 1.88.1 would be the right version to use with recent Theia versions.
2. The git extension is deprecated. Use the vs code git built-in instead.

The documentation you linked is supposed to serve as an example, not a recipe. In general, it's better to base Theia applications on the example application the the theia repo or on https://github.com/eclipse-theia/theia-blueprint.

See eclipse-theia/theia-website#587. Closing since we have an issue for the activation events and the other issue is suspected to be a configuration issue.
