gradlew: Permission Denied

You could use "bash" before command:

bash ./gradlew compileDebug --stacktrace

You need to update the execution permission for gradlew

Locally: chmod +x gradlew

Git:

git update-index --chmod=+x gradlew
git add .
git commit -m "Changing permission of gradlew"
git push

You should see:

mode change 100644 => 100755 gradlew

Try to set the execution flag on your gradlew file:

chmod +x gradlew

Could also be fixed with

git update-index --chmod=+x gradlew
