Processing qm file name error when using config embed_translations

When using config lrelease embed_translations, and split .ts file name with dot(.), qmake will only recognize the first part of the file name. For example, here is my project file:

CONFIG +=  lrelease embed_translations
TRANSLATIONS += example.en_US.ts example.zh_CN.ts

When build the project, I've got error:

error: No rule to make target `.qm/example.qm', needed by `qrc_qmake_qmake_qm_files.cpp'. Stop.

Because the ts filename is actually

example.xxxxx

not

example

Upload project files to attachment. Compile log:
