Problem

Maven as project build tool. Using Java generic function, when build with Maven, get this error message

generics are not supported in -source 1.3 (use -source 5 or higher to enable generics)

Solution

You need to tell Maven to use JDK 1.5 to compile your source code explicitly. Declare Maven compiler plugin (maven-compiler-plugin) in your pom.xml file, like this :

File : pom.xml

<project ...>
  <dependencies>
   ...
  </dependencies>
  <build>
    <plugins>
       <plugin>
           <groupId>org.apache.maven.plugins</groupId>
           <artifactId>maven-compiler-plugin</artifactId>
           <version>2.3.1</version>
           <configuration>
               <source>1.5</source>
               <target>1.5</target>
           </configuration>
       </plugin>
    </plugins>
  </build>
</project>
