Long image filenames result in assembleRelease crash

Is this a bug report?

Yes

Have you read the Contributing Guidelines?

Yes

Environment

1. react-native -v: 0.45.1
2. node -v: v8.2.1
3. npm -v: 5.3.0

• Target Platform: Android

• Development Operating System: macOS

• Build tools: compileSdkVersion 23 buildToolsVersion ‘25.0.0’

Steps to Reproduce

1. Create a file in a deep folder (e.g. /shared/components/Component/components/AnotherComponent/components/AnotherComponent/components/AnotherComponent/img/image.png)
2. Require that file
3. Run assembleRelease

Expected Behavior

Successful assembly

Actual Behavior

Assembly fails when processing the file:

.../app/android/app/build/intermediates/res/merged/release/drawable-mdpi/shared_components_component_components_anothercomponent_components_anothercomponent_components_anothercomponent_img_image.png: error: Invalid filename.  Unable to add.

:app:processReleaseResources FAILED

FAILURE: Build failed with an exception.

It’s probably the long filename that cannot be handled by Java. When I undeepen the structure, the problem disappears. If a hash of the path would be used as a filename, this problem would not exist.
