extent analysis

TL;DR

Set the required environment variables GITHUB_PERSONAL_ACCESS_TOKEN and GREPTILE_API_KEY to resolve the plugin configuration errors.

Guidance

  • The errors indicate missing environment variables for GitHub and Greptile plugins, suggesting a configuration issue.
  • Verify that the environment variables are set correctly in your system or IntelliJ configuration.
  • Check the documentation for the plugins to ensure you have the correct variable names and formats.
  • Consider setting the environment variables in your terminal or IntelliJ run configuration to test the fix.

Notes

The provided errors and environment information suggest a configuration issue, but without more context about the plugins or the system setup, it's difficult to provide a more specific solution.

Recommendation

Apply workaround: Set the required environment variables to resolve the plugin configuration errors, as this directly addresses the errors reported.
