Check your version of commons-lang, mine was version 2.6 used sudo find / | grep commons-lang
add to the dependencies before plugins and ensure id starts with I not i:
<dependency>
<groupId>commons-lang</groupId>
<artifactId>commons-lang</artifactId>
<version>2.6</version>
</dependency>
Does not build as per wiki there is no controller/opendaylight/distribution/opendaylight/target in order to ./run.sh So I am looking for that now ??

Since OP did not specify details I guess this may be about running maven on Ubuntu 14.
Maven packaging on Ubuntu seems to have some "issue".
After apt-get install maven in Ubuntu 14.04.1 LTS and attempting to package my project with mvn package I got the same exception.
Workaround from comment on github is:
sudo ln -s ../../java/commons-lang.jar /usr/share/maven/lib
That fixed maven at least in my case.

Fixed! I have downloaded manually maven 3.5 under https://maven.apache.org/download.cgi and copied file commons-lang3-3.5.jar to C:\Program Files\NetBeans 8.2\java\maven\lib\. I'm using NetBeans 8.2 with Maven as Plug-In.

Try adding this dependency in your pom.xml:
Copy<dependency>
<groupId>commons-lang</groupId>

<version>2.6</version>
</dependency>

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?
