 * If you want to run many Maven builds in parallel using Jenkins, try the [Port Allocator Plugin](https://wiki.jenkins-ci.org/display/JENKINS/Port+Allocator+Plugin) to avoid port conflicts.
 * If you need to use a proxy to download MongoDB then you can either use `-Dhttp.proxyHost` and `-Dhttp.proxyPort` as additional Maven arguments (this will affect the entire build) or instruct the plugin to use a proxy when downloading Mongo by adding the `proxyHost` and `proxyPort` configuration properties.
 * Using the `file` logging mode results in a new log file created at `./embedmongo.log`
+* If you'd like the start goal to start mongodb and wait, you can add `-Dembedmongo.wait` to your Maven command line arguments
