I apologize for my unclear description! Allow me to explain my problem
specifically. You are right; it is indeed a confusion.
Firstly, I compiled a project using Maven. This step was completed with the
command mvn clean install. Below is part of the output (I have omitted some
information for brevity).
[DEBUG] Dependency collection stats: {ConflictMarker.analyzeTime=316672,

My confusion is: based on the above situation, has the project actually
introduced the org.apache.commons:commons-lang3 with version 3.12.0 during the
actual compilation process?
I hope this clarifies my confusion.
