Android Studio 3.0 removes the execute permission from Gradle, breaking the build

Because of the ASF policy against bundling JARs, currently Cordova-Android uses a blank gradle file called wrapper.gradle and the Gradle that gets installed with Android Studio to install Gradle Wrapper on cordova projects. However, Google has recently changed the permissions on Androdi Studio 3.0 so that you can no longer use their bundled Gradle to to do this, which now breaks the build. We may now have to add Gradle as a dependency for cordova-android and we may have to increment the version to 7.0 because of this major breaking change.

Unfortunately, that means that the work planned for 7.0 is now going to be in 8.0, so there may be two major version bumps this year, which will be problematic.
