I was forced to manually do update the following files, because otherwise they would be ignored according .gitignore settings. Probably they should be deleted from repo. Interop/.idea/compiler.xml Interop/.idea/gradle.xml Interop/.idea/libraries/Gradle__org_jetbrains_kotlin_kotlin_runtime_1_0_3.xml Interop/.idea/libraries/Gradle__org_jetbrains_kotlin_kotlin_stdlib_1_0_3.xml Interop/.idea/modules.xml Interop/.idea/modules/Indexer/Indexer.iml Interop/.idea/modules/Runtime/Runtime.iml Interop/.idea/modules/StubGenerator/StubGenerator.iml backend.native/backend.native.iml backend.native/bc.frontend/bc.frontend.iml backend.native/cli.bc/cli.bc.iml backend.native/cli.bc/src/org/jetbrains/kotlin/cli/bc/K2Native.kt backend.native/cli.bc/src/org/jetbrains/kotlin/cli/bc/K2NativeCompilerArguments.kt backend.native/tests/link/lib/foo.kt backend.native/tests/link/lib/foo2.kt backend.native/tests/teamcity-test.property
