@WolfgangHG I think always printing out path would be "too much", Maven is
already way way too chatty... but here are few facts to tinker about:
* when descriptor reader reports this error all Maven "knows" that some POM
somewhere has some issue (uses system scoped dependency pointing at file that
does not exists)
* later on, when collection happened (built the "dirty graph" -> conflicts
resolved -> dep tree), just as in this example, the reported POM may not even
be present...
* still, IMO developer _should be aware_ of issues like these, as any
dependency change/reshuffle may make the offending POM end up in the build (in
reproducer is "just lurking somewhere" but is not entering

> Key: MNG-8177
> URL: https://issues.apache.org/jira/browse/MNG-8177
> Project: Maven
> Issue Type: Bug
> Components: Core
> Affects Versions: 3.9.8
> Environment: Java 11
> Reporter: Wolfgang Knauf
> Assignee: Tamas Cservenak
> Priority: Minor
> Fix For: 4.0.0, 3.9.9, 4.0.0-beta-4
>
>
> This warning pops up first with Maven 3.9.8, previous versions up to 3.9.7
> did not report it:
> {{[WARNING] 1 problem was encountered while building the effective model for
> org.jboss:jboss-dmr:jar:1.3.0.Final}}
> When using the "-X" switch, I see this additional message:
> {{[WARNING] 'dependencyManagement.dependencies.dependency.systemPath' for
> com.sun:tools:jar refers to a non-existing file
> C:\Temp\jdk-11.0.23\..\lib\tools.jar. Please verify that you run Maven using
> a JDK and not just a JRE. @ org.jboss:jboss-dmr:1.3.0.Final}}
>
> I run it with JDK 11, but downloaded the zip file only. There is no
> "tools.jar", which was removed as part of Java 9.
>
> To reproduce: create a project from this archetype:
> {{mvn archetype:generate -DarchetypeCatalog=local -DgroupId=com.acme
> -DartifactId=example-subsystem -Dversion=1.0-SNAPSHOT
> -Dmodule=org.test.subsystem -Dpackage=com.acme.example
> -DarchetypeGroupId=org.wildfly.archetype
> -DarchetypeArtifactId=wildfly-subsystem -DarchetypeVersion=32.0.0.Final
> -DinteractiveMode=false}}
>
> Then run this command to see the warning:
> {{mvn dependency:tree -X}}
>
> Actually, I don't know why jboss-dmr:1.3.0 is tested, as the project should
> reference jboss-dmr:1.7.0.
