Skip CLEAN - how to clean all the Android generated files and start fresh #228
-
|
I'm getting some Xcode Errors like: Execution failed for task 'app.compileDebugKotlin'. Configuring project ':SkipModel' without an existing directory is deprecated. I'm searching for a way to CLEAN the generated / derived files in the Android side of the dual platform. I see notes on cleaning the Xcode (iOS) side of things... but that does NOT clean the Android side. Seems like a Gradle CLEAN command or a Fastlane CLEAN command would be nice right about HERE. |

For Example - what happens if I just DELETE the .build (hidden folder)? |

Here is Xcode complaining about Main.kt UIApplication.launch(this) 
I'm looking thru the skip-grade.log.txt - but nothing seems to indicate what I should do about the issues in the log. |

If you're building from Xcode, then the .build folder shouldn't come into play, but you can delete it if you like. It can't hurt. To get a truly clean build you can do the same thing you do for iOS: tell Xcode to Clean and also delete DerivedData. When I see the error pictured above, my first question is whether you have an old version of skip-ui where UIApplication.launch does not exist. Make sure to run File->Packages->Update to Latest Versions to ensure you have the latest libraries. |

Ah... well a touch different after Update: Well - I'm always forgetting to Start up Android-Studio & a Pixel Virtual Device... but after restarting the world ... Something WORKED. So just so that I'm clear and not developing superstitions... You seem to be infering that deleting DeriedData folder is a WAY to Clean the Android side of the Dual project. I had done the Delete DeviredData folder a few times... it had not resolved my build issues... But ALL is well with the World NOW! Thanks Abe! |

I'd have to check the logs to see when UIApplication.launch was introduced, but I'm guessing that what fixed things here is just getting the latest libraries. And in general when you're building with Skip from Xcode, the pattern is the same as building without Skip: Generally just rebuilding should work. Occasionally you need to do a clean build because Xcode is caching something it shouldn't. And very occasionally, the only way to get Xcode to stop caching some old bit of data is to delete DerivedData. (Yes, when you build in Xcode, the Android side is being generated and built within DerivedData too) |

OK - for FUTURE ME... Xcode uses the DerivedData folder - to clean it use Xcode > Product > Clean Build Folder ; AND/OR delete DerivedData. |

Why use a hidden folder in the first place... try better Names: e.g. "fastbuild" to stick with Fastlane convention of "Fastfile" |
