IntelliJ Platform 2027.1

Several modules were extracted from the core plugin to separate modules with their own classloaders. This shouldn't affect binary compatibility, but an explicit dependency should be added in build.gradle.kts using bundledModule(<moduleName>) if a plugin uses API from these modules:

  • intellij.platform.execution

  • intellij.platform.execution.impl
