Flutter Execution failed for task ':app:processDebugResources'

Question

I left my flutter project for a while when Flutter beta v1.0.0 was out. Now I moved my project to a new system with latest Flutter (stable v1.2.1) and Dart and ran into this build exception problem.

Note this project is working fine on my old desktop flutter doctor output below

Are you using any firebase dependencies? Could you add your `pubspec.yaml', dependencies section to your question? — RhysD
– RhysD, Commented Mar 25, 2019 at 17:56
@R.Duggan no I don't have any firebase question. Also I have updated the question — Nadeem Siddique

The missing resources were only added in API 28. You need to update your compileSDKversion in your build.gradle file to version 28.

how do you get to know about these? like seriously im curious.

Izabela Orlowska Over a year ago

A big hint was that they were referenced in "values-v28" (API 28+). You can check out AOSP source code and see where they were added.

you save my life!

Thank you! In my case, after changing the compiledSdkVersion, I had to change the GradleException to Exception in the next line: throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")

you saved hours :)

add this line in gradle.properties

org.gradle.jvmargs=-Xmx1536M --add-exports=java.base/sun.nio.ch=ALL-UNNAMED --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.lang.reflect=ALL-UNNAMED --add-opens=java.base/java.io=ALL-UNNAMED --add-exports=jdk.unsupported/sun.misc=ALL-UNNAMED
