Deploy artifact to Maven repository that has no file extension

Help/Discuss

I want to deploy binary artifacts (Linux and Mac OS X executables) to a Maven repository using Gradle’s MavenPublication such that they are stored in the repository without a file extension (as is the case by default for binaries/executables on Linux and Mac).

Say I have a binary foo in version 1.0.0; in Maven terminology these would be the artifactId and version, respectively. The closest I can get is to deploy it under the name foo-1.0.0. - note the trailing dot (.). I would rather want it to be stored under the name foo-1.0.0 (i.e., without the dot). I tried not specifying the extension property, and I also tried specifying an empty extension=''.

publishing {
  publications {
    maven(MavenPublication) {
      artifact("some/parent/dir/foo") {
        extension ''
      }
    }
  }
}

Is it possible to achieve this?
