I am reading an effective POM from the command line (using the approach described here: How to specify an artifact in help:effective-pom?)
For the artifact:
<dependency>
<groupId>com.typesafe.scala-logging</groupId>
<artifactId>scala-logging_2.12</artifactId>
<version>3.7.2</version>
</dependency>
Using the command:
mvn help:effective-pom -Dartifact=com.typesafe.scala-logging:scala-logging_2.12:3.7.2
I get this error:
