Howdy,
you can see the "build plan" which is not DAG, but the ordered list out of
DAG (sorted nodes in order DAG requires), just use `-X` on the command line.
But again, this list does not reflect in reality "how the build is gonna
execute"...
As regarding the actual "build order", it depends on Builder implementation:
See here:
https://github.com/apache/maven/blob/master/maven-core/src/main/java/org/apache/maven/lifecycle/internal/builder/Builder.java
and package (with ST and MT Builders in subpackages)
https://github.com/apache/maven/tree/master/maven-core/src/main/java/org/apache/maven/lifecycle/internal/builder
Also, there are "alternative" Builders like this one
https://github.com/takari/takari-smart-builder/blob/master/src/main/java/io/takari/maven/builder/smart/SmartBuilder.java
You can get more explained here, but most you can get is by reading sources
above
