Maven refusing to compile Spring project due to annotations

The fix for the following issue is here http://maven.40175.n5.nabble.com/Maven-refusing-to-compile-Spring-project-due-to-annotations-tp4309204p4309211.html. Duh!

I’m running Eclipse and Maven on a Mac. Here’s my version of Maven

$ mvn -version
Apache Maven 2.2.1 (r801777; 2009-08-06 20:16:01+0100)
Java version: 1.6.0_22
Java home: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
Default locale: en_US, platform encoding: MacRoman
OS name: "mac os x" version: "10.5.8" arch: "x86_64" Family: "mac"

What I’m trying to do is use Maven to compile my Spring project (it builds fine in Eclipse) so I can deploy the war to a Tomcat. I setup my pom.xml (see below) and asked mvn to create the package. The build failed with the following error:

Compilation failure
/path/to/WelcomeController.java:[7,1] annotations are not supported in -source 1.3
(use -source 5 or higher to enable annotations)
@Controller

Doing mvn compile gives the same error. Google showed me that this was a known problem with Maven with the fix explained here:

http://maven.apache.org/plugins/maven-compiler-plugin/howto.html

I can’t see why the fix isn’t working for me. In desparation I followed these instructions:

http://pwong-tipsandtricks.blogspot.com/2009/02/install-and-test-maven-on-centos-52.html and put a fresh maven on my Linux box. The build failed with the same error, so it seems that my pom.xml is the culprit. But how? Here’s the pom.
