Is it possible to publish source to JCenter to the root of repository?

I need to publish some text file some.txt to the root of my repository on JCenter.
Not under version-specific.

  • The group name is (example only)
  • The POM ARTIFACT ID is my-android-pack

I know with gradle I can publish some packaged libraries aar with the following configuration:

pom.project {
            name MyProject
            packaging aar
            artifactId my-android-pack
            version 1.2.3

where all fields are required.

Do you know any other way to upload the file to JCenter? Is it possible to upload txt file?

I know only jar, war, and ear types allowed.
