NoClassDefFoundError : org.apache.commons.lang.StringUtils

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.

Try adding this dependency to your pom.xml

<dependency>
    <groupId>commons-lang</groupId>
    <artifactId>commons-lang</artifactId>
    <version>2.6</version>
</dependency>

You do not declare commons-lang as a dependency. Add

<dependencies>
<dependency>
    <groupId>commons-lang</groupId>
    <artifactId>commons-lang</artifactId>
    <version>2.3</version>
</dependency>
</dependencies>

To your pom.xml

Your pom.xml should looks like:

<dependencies>
<dependency>
    <groupId>commons-lang</groupId>
    <artifactId>commons-lang</artifactId>
    <version>2.3</version>
</dependency>
</dependencies>
