The compiler api changed a lot.\n\nIMHO CodeQL should use the (experimental) analysis api, the same api IntelliJ, dokka and detekt is using, because it is somehow more stable and CodeQL only reads the code. The current IR plugin is too low-level (and can change the code).\n\nError message: `Kotlin version 2.4.0 is too recent. CodeQL currently supports versions below 2.3.30`\n\nPR: https://github.com/github/codeql/pull/21970","author":{"url":"https://github.com/hfhbd","@type":"Person","name":"hfhbd"},"datePublished":"2026-06-04T07:05:21.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/21938/codeql/issues/21938"}
