Maven refusing to compile Spring project due to annotations

[snowb0y]

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 so I can deploy the packaged 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 the 1.3-compiler-as-default was a known problem with Maven and I was happy to find a fix explained here: http://maven.apache.org/plugins/maven-compiler-plugin/howto.html

But it's still not working ): In desperation 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. Any ideas welcome!

What kind of error do you have once you set the source and target parameter
of the maven compiler plugin to 1.5 ?

"Legacy code" often differs from its suggested alternative by actually
working and scaling.

Well, you should use the maven-compiler-plugin as described in
http://maven.apache.org/plugins/maven-compiler-plugin/howto.html, not
the maven-eclipse-plugin.

Hi Jeff,

Thanks for reply. It's the same error with these 3 variations.

        <configuration>
          <wtpversion>1.5</wtpversion>
        </configuration>

        <configuration>
          <source>1.5</source>
          <target>1.5</target>
        </configuration>

        <configuration>
          <source>1.6</source>
          <target>1.6</target>
        </configuration>

The pom used to have a parent from a repo at my place of work. My goal is to get the build working without the parent as this isn't a work project. But then the compile error kicked in ..

Hi Manuel,

Well seen! Worked straight away. Thanks for your post.
