[FIXED] Maven: How is a phase mapped to a lifecycle

Issue

i'm wondering about how Maven maps a phase to a lifecycle.

For example when running

mvn clean

then Maven executes the phases "pre-clean" and "clean" of the "clean" lifecycle.

But how does Maven determine that the phase "clean" (as provided as command line argument) belongs to the "clean" lifecycle? There could be another lifecycle that also has a "clean" phase.

It may be a rule that all phases over all lifecycles must have a unique name. But i don't know.

Solution

In Maven there existing only the following three life cycles

1. clean
2. default
3. site

The details are defined in the lifecycle binding of Maven core https://maven.apache.org/ref/3.8.1/maven-core/lifecycles.html

The existing and defined life cycles are defined in the following file:

META-INF/plexus/components.xml
