To include the JSON-lib library as a dependency to our Maven project we must not forget to use the classifier
element. Otherwise the library will not be added to our project, because it cannot be downloaded from the repositories.
<dependency> <groupId>net.sf.json-lib</groupId> <artifactId>json-lib</artifactId> <version>2.2.3</version> <classifier>jdk15</classifier> </dependency>
