Build failure on debian 9.9 (stretch)

I am able to build swagger2markup but swagger2markup-cli on my Debian installation.

Environment

$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 9.9 (stretch)
Release: 9.9
Codename: stretch
$ uname -a

First I tried using gradlew

swagger2markup-cli$ ./gradlew

Reading around this has something do with having an old version of gradle.
So I installed the latest 6.0 using stackman (as suggested here - https://stackoverflow.com/questions/54358107/gradle-could-not-determine-java-version-from-11-0-2)

I now get a different problem:

gradle assemble --debug --info

I found a workaround. The parent project mentions bintray which led me to:

https://jcenter.bintray.com/io/github/swagger2markup/swagger2markup-cli/1.3.3/

The download link has a spurious colon added for some strange reason. The actual download is here (rather than :swagger2markup-cli-1.3.3.jar):

wget https://jcenter.bintray.com/io/github/swagger2markup/swagger2markup-cli/1.3.3/swagger2markup-cli-1.3.3.jar

This jar seems to work. So there is a working binary installation available.
For people like me who are not used to gradle it would be useful to advertise this option on the main page.

You could also use the docker container, if you don't want to install java.
