Buck doesn't generate Manifest files when modules are being built

Created by: kirillzh

We are getting "current min is 1" in IJ for certain Android APIs in Android modules even though our min SDK is set properly (through okbuck + gradle). Here's BUCK config:

okbuck_manifest(
    name = 'manifest_lib_debug',
    main_manifest = 'src/main/AndroidManifest.xml',
    min_sdk = '21',
    target_sdk = '26',
    package = 'com.squareup.common.tutorial',
    version_code = '1',
    version_name = '1.0',
    debuggable = True,
)

We are currently on OkBuck 0.47.1 and Buck f8a27c9137515046c02b1b444732f5eae270b6b9.

Example of warning:

Running ./buckw project --skip-build nor building the module ./buckw build //common/tutorial:src_debug solves the problem. However, manually running manifest_lib_debug target does. Anyway to solve that problem when the module is being built, at very least?

Thank you.
