通过检查库的POM文件解决了.我注意到即使将POM添加到我的build.gradle文件中，该文件也缺少了Firebase数据库依赖项，这意味着发布到Bintray gradle任务出了点问题！

Solved by checking the POM file of my library. I noticed that the firebase database dependency was missing from the POM file even though i have added it to my build.gradle, which means something went wrong with the publish to bintray gradle task!

我已经解决了gradle任务，现在一切正常.

I made a fix to the gradle task and now all good.
