I want to create an archetype from an existing project, for which I place myself in the directory where the POM.XML of this project is and execute the instruction
mvn archetype:create-from-project
resulting in
java.lang.NoClassDefFoundError: org/apache/commons/lang/StringUtils
I have Maven version 3.3.9 installed, and I use JDK 1.8. Also, as you can see in the trace, the common-lang library exists in my library repository (although it seems to be using 2.4 when I checked that I have also downloaded 2.6).
I've also tried other maven instructions like "generate" and always gives the same error.
On the other hand, the project compiles without problems.
This is the trace of the error
