However, I get the error mentioned below:
Buildfile: C:\Code\Organic\eclipse-workspace\DemoSite\site\build.xml
start-db:
[artifact:pom] An error has occurred while processing the Maven artifact tasks.
[artifact:pom] Diagnosis:
[artifact:pom]
[artifact:pom] Unable to initialize POM pom.xml: Failed to validate POM for project com.mycompany:site at C:\Code\Organic\eclipse-workspace\DemoSite\site\pom.xml

BUILD FAILED
C:\Code\Organic\eclipse-workspace\DemoSite\site\build.xml:95: Unable to initialize POM pom.xml: Failed to validate POM for project com.mycompany:site at C:\Code\Organic\eclipse-workspace\DemoSite\site\pom.xml
Total time: 4 seconds
I am using the eclipse-workspace downloaded from the website. The DemoSite\site\build.xml and DemoSite\site\pom.xml have been attached below for reference.
Any help would be greatly appreciated.
