In the repository I see that in commons-lang/commons-lang/ folder
there are four of them 2.1, 2.4, 2.5, 2.6 but 2.1 and 2.4 has no jar in the folder just the other files. There are jars in 2.5 and 2.6 folders.
And in org/apache/commons/commons-lang3 folder I see one 3.1 with the jar
I have broken this down to the point of absolute basic observation so that someone with the similar experience could help me out.
回答1:
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 ??
回答2:
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.
回答3:
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>

回答4:
For me it seems that the problem was in accessing artifact in local maven repository, so I just deleted the whole org/apache folder from local maven repo and it fixed the problem.
回答5:
Try adding this dependency to your pom.xml
<dependency>
<groupId>commons-lang</groupId>
<artifactId>commons-lang</artifactId>
<version>2.6</version>
</dependency>

org.apache.commons.lang.StringUtils missing when running Maven on Ubuntu
Some Maven goals like site:stage fail under Ubuntu 14.04 with
A required class was missing while executing
org.apache.maven.plugins:maven-site-plugin:3.4:stage: org/apache/commons/lang/StringUtils
This happens if you use the Ubuntu Maven package which misses the commons-lang dependency. You can either unpack a stand-alone Maven archive or use the following commands:
cd /usr/share/maven/lib
sudo ln -s ../../java/commons-lang.jar .

回答7:
You should change commons-lang3.jar dependency version using in pom.xml. if you are doing code in java simple project add another jar whatever version you are using. or you can check jar replication shouldn't be there.
