I'm following the book Alfresco Developer Guide 2009.
"the examples in this book use Apache Ant to package and deploy the customizations to your local Alfresco web application. The build.xml file referos to a build.properties file. The build.properties file should be used to specify variables specific to your setup. If you set your Eclipse project folder structure as described earlier (and i did), you shouldn't have to edit the build.xml file; the build.properties file should be all you need to touch. The source cod that accompanies this chapter includes a build.properties.sample file. Rename it to biold.properties and then edit to point to expanded Alfresco SDK and the explded Alfresco webbapp directory in Tomcat."
I thought that there was a sample file in the sdk. So i have to create a new build.properties file to link my customization to my Alfresco?
