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 ??

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?

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.

Your scope should not be provided unless you're deploying to a host where it will, somehow, already be provided. Use compile instead.

Thanks for all replies, i solved it by downloading manually the .jar file from the following link and overwrite the existing jar downloaded by maven. (i don't know why it started working after manual download, but after all, its working)

http://commons.apache.org/proper/commons-lang/download_lang.cgi

Download apache-lang common from apache jakarta sie:

http://commons.apache.org/lang/

After getting jar file please put this jar in your project's build path, if you are not able to find build path then go Jdeveloper help file and type "build path" and you will get all intrustion over there.

I received the same error, I added to my pom.xml file the following lines and worked fine after maven install:

<dependencies>

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

</dependencies> 

Try adding org.apache.commons.lang in the Dependencies section of your META-INF/MANIFEST.MF file.

I think the problem is that you are not declaring the dependency, so JBoss is not loading the class for you..

Hope it helps!

EDIT: You can set this up through maven using maven-war-plugin or maven-ear-plugin. Here's an example:

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.1.1</version>
    <configuration>
        <failOnMissingWebXml>false</failOnMissingWebXml>

        <!-- Maven will append the version to the finalName (which is the name 
            given to the generated war, and hence the context root) -->
        <warName>${project.artifactId}</warName>

        <archive>
            <manifestEntries>
                <Dependencies>org.apache.commons.lang</Dependencies>
            </manifestEntries>
        </archive>
    </configuration>
</plugin>
