negative.code: * it prefers a local installation
  * if docker is available and no local installation, it will use docker. The download of the images might take a while when run for the first time
  * if docker is not available, it will download and install docToolchain to your home folder
  ** it will then run a gradle build through the gradle wrapper. This will download and install gradle when run for the first time.
  ** the gradle build will also fetch some dependencies. This will also take some time when run for the first time.
  
  As you can see, the installation is an incremental process and will take some time because of additional downloads.
