Try running the following commands and examine the output:

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

Look for commons-lang, maybe something will draw your attention like excludes or dependency overrides. Also, is:

$ mvn dependency:copy-dependencies

copying commons-lang JAR to your target?

Check the Maven Central Repository for the latest version of 'commons-lang' and update your pom.xml accordingly: Clear and rebuild your local Maven repository using 'mvn clean install' or 'mvn clean validate' commands. Mistake: Not adding the dependency to the right section in the pom.xml.
