Execution failed for task & Could not delete path

Question

I have react-native based app and every time I run it via famous react-native run-android. Most of the times it works, but almost every day I get this error when running, and the only thing I can do to fix it, is to pull the whole project again in the different directive. Aka. start all over.

* What went wrong:
Execution failed for task ':app:processDebugResources'.
> java.io.IOException: Could not delete path 'C:\Users\John\Documents\React-projects\insta-clone3\mobile\android\app\build\generated\source\r\debug\com\aurelhubert'.

Always the same exeception, Could not delete path. This is my build.gradle

android {
compileSdkVersion 26
buildToolsVersion "25.0.1"

defaultConfig {
    applicationId "com.instagramclone"
    minSdkVersion 16
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
    ndk {
        abiFilters "armeabi-v7a", "x86"
    }
}

None of the solutions I found online does not seem to work for me.

What do you mean by that? Any concrete line of code to execute? @Artyom — Learn on hard way, Mar 23 '18 at 11:12
`gradlew clean` command from Android project root (`C:\Users\John\Documents\React-projects\insta-clone3\mobile\android` in your case) — Artyom, Mar 23 '18 at 11:16
I have got `symbol: variable BuildConfig` after doing that. Again some error @Artyom — Learn on hard way, Mar 23 '18 at 11:34
This is the reason why it crashed `Execution failed for task ':app:compileDebugJavaWithJavac'.` — Learn on hard way, Mar 23 '18 at 12:01

Have you tried deleting the android/app/build folder before running react-native run-android ? In the error message you can see that something fails in android/app/build/generated/...

I'm sure there is another way besides deleting the whole `build` directory. – Learn on hard way Mar 23 '18 at 13:31

Try these commands in root directory

./gradlew clean

Then go back to root and try again

First enter these commands:

cd android
./gradlew.bat installDebug

After that,

cd..
react-native run-android

It works fine for me.
