Often you have the problem that in large builds, you need to find where time is consumed.
This is an EventSpy implementation which collects all the information of all phases and mojo executions and make a summarization output at the end of the build.
If you like to use this EventSpy with Maven 3.1.1+ till Maven 3.2.5 you need
to manually download it from Maven Central and put the resulting jar
file into the ${M2_HOME}/lib/ext directory or if you
like to use it directly you have to add the following parameter on command line:
mvn -Dmaven.ext.class.path=PathWhereItIsLocated/maven-buildtime-profiler-0.2.0-mvn311.jar clean package
If you like to use this extension for Maven 3.3.1+ you
have to define the following .mvn/extensions.xml file:
<extensions xmlns="http://maven.apache.org/EXTENSIONS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/EXTENSIONS/1.0.0 http://maven.apache.org/xsd/core-extensions-1.0.0.xsd">
<extension>
<groupId>com.soebes.maven.extensions</groupId>
<artifactId>maven-buildtime-profiler</artifactId>
<version>0.2.0</version>
</extension>
</extensions>The download from Maven Central will be done by Maven itself.
Here's an example of what the output will look like:

Most important might be in this relationship that you will get also informations about the time taken to install artifacts:

Prerequisites minimum for this is Maven 3.1.1+ and Java 1.8 as run time.
If you have ideas for improvements etc. just fill in issues in the tracking system.
