我想像这样嵌套我的模块
payment
contract
impl
transaction
contract
impl
即payment:contract, payment:impl, transaction:contract, transaction:impl
但是gradle抱怨存在重复的impl模块（和合同）
More than one file was found with OS independent path 'META-INF/impl_debug.kotlin_module'.
如何做到这一点，而不将其重命名为transaction:transaction-contract或不嵌套？
