Check out this repo\n2. Run `./gradlew compileKotlin`\n3. Observe failure that starts out like this:\n```\n\u003e Task :compileKotlin FAILED\ne: Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:\n    class com.google.protobuf.DescriptorProtos.DescriptorProto.Builder, unresolved supertypes: DescriptorProtoOrBuilder\n[.. much output trimmed ..]\n```\n\n## Compare behaviour against kotlin 1.6.21\n\n1. Modify the build.gradle.kts file to use the Kotlin 1.6.21 compiler (comment out the 1.7.0 plugin and uncomment the 1.6.21 line)\n2. Run `./gradlew compileKotlin`\n3. Observe the build succeeds.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstaktrace%2F20220720-kotlin-compiler-regression","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fstaktrace%2F20220720-kotlin-compiler-regression","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstaktrace%2F20220720-kotlin-compiler-regression/lists"}
