The StringUtils class was not found at Maven compile time

Today on Jersey's official website, execute the command as follows:

MVN archetype:generate-darchetypeartifactid=jersey-quickstart-grizzly2 \

-darchetypegroupid=org.glassfish.jersey.archetypes-dinteractivemode=false \

-dgroupid=com.example-dartifactid=simple-service-dpackage=com.example \

-darchetypeversion=2.21

The following error occurred while generating the jersey code:

Ype-plugin:2.4:generate failed:a required class is missing while executing org.apache.maven.plugins: Maven-archetype-plugin:2.4:generate:org/apache/commons/lang/stringutils

...

Problem cause Analysis: You can see from the error message that the Commons-lang StringUtils class was not found when executing the Maven-archetype-plugin plugin. By viewing the MAVEN local repository Maven-archetype-plugin-2.4.pom file, you find that the dependencies for the Commons-lang package are not configured, so configure the following dependencies:

  <dependency>
      <groupId>commons-lang</groupId>
      <artifactid>commons-lang</ artifactid>
      <version>2.3</version>
 </dependency>

Re-execute the above command, OK.
