I've added a maven dependency for StringUtils (org.apache.commons.lang)
<dependency>
<groupId>commons-lang</groupId>
<artifactId></artifactId>
<version>2.6</version>
</dependency>
I want to see javadoc of that jar , otherwise the javadoc for each functions in (org.apache.commons.lang) when I point the cursor in this function, is there some dependency for it?
