Try running the following commands and examine the output:

$ mvn dependency:tree
$ mvn help:effective-pom

$ mvn dependency:copy-dependencies

copying commons-lang JAR to your target?

org.apache.commons.lang3 (Apache Commons Lang 3.20.0 API)
Provides highly reusable utility methods, chiefly concerned with adding value to the java.lang classes. Most of these classes are immutable and thus thread-safe. However CharSet is not currently guaranteed thread-safe under all circumstances. The top level package contains various Utils classes, whilst there are various subpackages including org.apache.commons.lang3.math, org.apache.commons.lang3.concurrent and org.apache.commons.lang3.builder.
