A time execution recorder for Maven which log time taken by each mojo in your build lifecycle.
$M2_HOME refers to maven installation folder.

You can install a pre-packaged maven named maven-deluxe using brew.
It comes with maven-color, maven-notifier and maven-profiler.
It is based on latest maven release.
brew tap jcgay/jcgay
brew install maven-deluxe
Get maven-profiler and copy it in %M2_HOME%/lib/ext folder.
or
Use the core extensions configuration mechanism by creating a ${maven.multiModuleProjectDirectory}/.mvn/extensions.xml file with:
<?xml version="1.0" encoding="UTF-8"?>
<extensions>
<extension>
<groupId>fr.jcgay.maven</groupId>
<artifactId>maven-profiler</artifactId>
<version>3.2</version>
</extension>
</extensions>
Get maven-profiler and copy it in %M2_HOME%/lib/ext folder.
(with limited functionality, kept for compatibility)
Get maven-profiler and copy it in %M2_HOME%/lib/ext folder.
Use property profile when running Maven.
mvn install -Dprofile
This will generate a report in .profiler folder.
You might also add a profile name, which is included in the report and helps identify the experiment:
mvn clean install -Dprofile="No custom JVM options"
export MAVEN_OPTS='-XX:TieredStopAtLevel=1 -XX:+UseParallelGC'
mvn clean install -Dprofile="With custom JVM options=${MAVEN_OPTS}"
The extension also works when mvn is executed on multiple threads (option -T).
One can choose between HTML (by default), JSON or CONSOLE report using property profileFormat.
mvn install -Dprofile -DprofileFormat=HTML
Or you can compose multiple reporters separated by comma:
mvn install -Dprofile -DprofileFormat=JSON,HTML,CONSOLE
Also you can add the property disableTimeSorting if you want the reported times to be in the order of execution instead of sorted by execution time.
mvn install -Dprofile -DdisableTimeSorting
Report default directory (.profiler) can be customized.
You can set it as a Maven property, for example in pom.xml:
<properties>
<maven-profiler-report-directory>${project.build.directory}/custom-directory</maven-profiler-report-directory>
</properties>
or you can define it using a system property:
mvn install -Dprofile -Dmaven-profiler-report-directory=/tmp/profiler-custom-report
User parameters could leak sensitive data, you can disable reporting them using:
mvn install -Dprofile -DhideParameters=true
mvn install -Dprofile
mvn install -Dprofile -DprofileFormat=JSON
