quarkus-maven-plugin does not obey --file -f command line flag

[zeljkot]

Describe the bug
When --file is specified on command line (e.g. mvn --file pom2.xml quarkus:dev) it is ignored. Quarkus plugin either loads pom.xml or complains that there is no pom.xml.

Expected behavior
Plugin should use specified file.

Actual behavior
Plugin ignores the flag and always uses pom.xml.

To Reproduce
Steps to reproduce the behavior:

1. Rename pom.xml to pom2.xml.
2. mvn --file pom2.xml quarkus:dev

[ERROR] The goal you specified requires a project to execute but there is no POM in this directory (D:\Atron\repo\asc\import-aservice-quarkus). Please verify you invoked Maven from the correct directory. -> [Help 1]

Configuration

@gsmet IMHO this should be labeled as area/maven or area/devtools
