Profiles the time spent in various parts of a maven build.
Add -Dmaven.ext.class.path=maven-mojo-timer.jar to your mvn command.
Add a .mvn/extension.xml file to your project containing
<?xml version="1.0" encoding="UTF-8"?>
<extensions>
<extension>
<groupId>nl.future-edge</groupId>
<artifactId>maven-mojo-timer</artifactId>
<version>1.0.0</version>
</extension>
</extensions>
After the build the extension reports the cumulative time spent by various parts of the build:
| name | description |
|---|---|
| maven:settings-building | Build setup (settings) |
| maven:toolchains-building | Build setup (toolchains) |
| maven:dependency-resolution | Dependency resolution |
| maven:repository:artifact-download | Downloading artifacts |
| maven:repository:artifact-deployment | Deploying artifacts |
| <groupId>:<artifactId>:<goal>:<executionId> | Mojo executions |
