Suppose you want to download ```druid-rabbitmq```, ```mysql-metadata-storage``` and ```hadoop-client```(both 2.3.0 and 2.4.0) with a specific version, you can run `pull-deps` command with `-c io.druid.extensions:druid-examples:#{DRUIDVERSION}`, `-c io.druid.extensions:mysql-metadata-storage:#{DRUIDVERSION}`, `-h org.apache.hadoop:hadoop-client:2.3.0` and `-h org.apache.hadoop:hadoop-client:2.4.0`, an example command would be:
```
java -classpath "/my/druid/library/*" io.druid.cli.Main tools pull-deps --clean -c io.druid.extensions:mysql-metadata-storage:#{DRUIDVERSION} -c io.druid.extensions.contrib:druid-rabbitmq:#{DRUIDVERSION} -h org.apache.hadoop:hadoop-client:2.3.0 -h org.apache.hadoop:hadoop-client:2.4.0
java -classpath "/my/druid/lib/*" io.druid.cli.Main tools pull-deps --clean -c io.druid.extensions:mysql-metadata-storage:#{DRUIDVERSION} -c io.druid.extensions.contrib:druid-rabbitmq:#{DRUIDVERSION} -h org.apache.hadoop:hadoop-client:2.3.0 -h org.apache.hadoop:hadoop-client:2.4.0
```
Because `--clean` is supplied, this command will first remove the directories specified at `druid.extensions.directory` and `druid.extensions.hadoopDependenciesDir`, then recreate them and start downloading the extensions there. After finishing downloading, if you go to the extension directories you specified, you will see

Note that if you specify `--defaultVersion`, you don't have to put version information in the coordinate. For example, if you want both `druid-rabbitmq` and `mysql-metadata-storage` to use version `#{DRUIDVERSION}`, you can change the command above to
```
java -classpath "/my/druid/library/*" io.druid.cli.Main tools pull-deps --defaultVersion #{DRUIDVERSION} --clean -c io.druid.extensions:mysql-metadata-storage -c io.druid.extensions.contrib:druid-rabbitmq -h org.apache.hadoop:hadoop-client:2.3.0 -h org.apache.hadoop:hadoop-client:2.4.0
java -classpath "/my/druid/lib/*" io.druid.cli.Main tools pull-deps --defaultVersion #{DRUIDVERSION} --clean -c io.druid.extensions:mysql-metadata-storage -c io.druid.extensions.contrib:druid-rabbitmq -h org.apache.hadoop:hadoop-client:2.3.0 -h org.apache.hadoop:hadoop-client:2.4.0
