Download commons-lang and throw it into your /WEB-INF/lib folder.
If its not a web application you have to check how you can add it to your build path with JDeveloper.
java.lang does not contain a class called StringUtils. Several third-party libs do, such as Apache Commons Lang or the Spring framework. Make sure you have the relevant jar in your project classpath and import the correct class.
StringUtils is an Apache Commons project. You need to download and add the library to your classpath.
To use:
import org.apache.commons.lang3.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.
