Compilation Failure when running as Maven Package

Question

I got this BUILD error when I run as Maven Package. But I'm not sure what's the error. Can anyone help? Thanks in advance.

"error: generics are not supported in -source 1.3"

Im guessing your code uses generics and the compiler is told to use java 1.3 which does not support such.

edit: you might have to use at least java 1.5

 <project>
 [...]
   <build>
   [...]
   <plugins>
     <plugin>
     <groupId>org.apache.maven.plugins</groupId>
     <artifactId>maven-compiler-plugin</artifactId>
     <version>2.3.2</version>
     <configuration>
       <source>1.5</source>
       <target>1.5</target>
     </configuration>
   </plugin>
  </plugins>
  [...]
  </build>
 [...]
 </project>

Add this to your Maven POM:

<build>
  [...]
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>2.3.2</version>
        <configuration>
          <!-- set compliance level here -->
          <source>1.6</source>
          <target>1.6</target>
        </configuration>
      </plugin>
    </plugins>
  [...]
</build>

BTW, current versions of Maven assume 1.5 as default compliance level. Perhaps you should upgrade to a current Maven version.

Sorry, how do I add this? I see pom.xml. Do I add this in? – Wallace Sep 16 '11 at 22:36
