embedmongo-maven-plugin

Maven plugin wrapper for the flapdoodle.de embedded MongoDB API.

This plugin lets you start and stop an instance of MongoDB during a Maven build, e.g. for integration testing. The Mongo instance isn't strictly embedded (it's not running within the JVM of your application), but it is a managed instance that exists only for the lifetime of your build.

Notes

• By default, the start goal is bound to pre-integration-test, the stop goal is bound to post-integration-test. You can of course bind to different phases if required.
• If you omit/forget the stop goal, any Mongo process spawned by the start goal will be stopped when the JVM terminates.
• If you want to run Maven builds in parallel you can use randomPort to avoid port conflicts, the value allocated will be available to other plugins in the project as a property embedmongo.port. If you're using Jenkins, you can also try the Port Allocator Plugin.
• 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.
• If you're having trouble with Windows firewall rules, try setting the bindIp config property to 127.0.0.1.
• If you'd like the start goal to start mongodb and wait, you can add -Dembedmongo.wait to your Maven command line arguments
