After publishing library on bintray i received one mail from support. Below
Bintray (bintray) has sent you a direct message from Bintray:
Hi,
JCenter hosts java applications that follow maven convention. In addition to the .pom file, your version should include a binary jar file, a sources jar, and optionally a javadoc jar. Your files should be under a maven path layout. (see https://bintray.com/docs/usermanual/uploads/uploads_includingyourpackagesinjcenter.html)
Once those files are added, we'll be glad to include your package in JCenter
Last activity on bitray account showing library released. What's the step need to follow now. Any help will be appreciated. Thanks
