Usage: Start the Docker container and run the ./download.sh script as follows:
./download.sh <MAVEN_ARTIFACT_ID> <OUTPUT_DIRECTORY>
The script will download the artifact without version to the output directory. E.g.:
./download.sh de.aservo:confapi-crowd-plugin:0.0.8:jar ./plugins
This will result in:
$ ls ./plugins
confapi-crowd-plugin.jar
