I am trying to code in Kotlinin Android Studio 3.0 Canary 2. When I make changes to the code, I have to rebuild the full application from the Build -> Rebuild Project, and then run
After making changes to the code, just when I press the start button, it shows this error randomly.
Error: execution completed for task ': app: javaPreCompileDebug'. java.io.IOException: Failed to delete C: \ Users \ williams \ AndroidStudioProjects \ Kotlin \ FirstDemo \ app \ build \ intermediates \ javaPrecompile \ debug \ annotationProcessors.json
What could be the problem? There seems to be a problem with the assemblers or the compiler Kotlinas it works fine with Java.
