Android gradle构建错误“找不到<dependency>”

Question

在我的项目中，有一个模块需要依赖，该依赖关系位于bitbucket中。当我尝试构建它找不到依赖项。我在哪里错了？

错误：

Could not resolve all dependencies for configuration ':app:_debugApk'.
A problem occurred configuring project ':react-native-mqtt-iot'.
Could not resolve all dependencies for configuration ':react-native-mqtt- iot:_debugPublishCopy'.
Could not find co.ibhubs.ibchat:ibchat:0.0.1. Required by:project :react-native-mqtt-iot

build.gradle文件

def computeVersionName() {
    // dynamically retrieve version from package.json
    def slurper = new JsonSlurper()
    def json = slurper.parse(file('../package.json'), "utf-8")
    return json.version
}
