#Overview Maven doesn't give you detailed information about where you build is taking the most time. This build time extension displays the duration for each goal that is ran during your build.

Usage

Put this in your pom.xml to find out why you are slow.

<build>
    <extensions>
        <extension>
            <groupId>co.leantechniques</groupId>
            <artifactId>maven-buildtime-extension</artifactId>
            <version>1.0</version>
        </extension>
    </extensions>
</build>

StatsD Integration

Timing data can be sent to StatsD if the following properties are defined in the top-level project's pom:

• buildtime.statsd.host: (required) the host to send metrics to
• buildtime.statsd.port: optional port for statsd (default is 8125)
• buildtime.statsd.prefix: optional prefix to include in StatsD metrics (default is "buildtime")

Example Property Defininition:

<properties>
	<!-- Required to send stats -->
	<buildtime.statsd.host>mystatsd</buildtime.statsd.host>
	
	<!-- Optional prefix -->
	<buildtime.statsd.prefix>myproject.build</buildtime.statsd.prefix>
</properties>
