I’ve downloaded source codes from Git Repository with Eclipse (Version: Mars.2 Release (4.5.2)) and is trying to build codes, but I’ve encountered several build errors and could not resolve them after much investigation. Please find the error information as below.

- After downloading codes with Eclipse and running Maven clean install, I get Maven Build Success.

- And after going to [http://localhost:8080/](http://localhost:8080/), is seems my Webapp is running well.

- [Build Error in pom.xml] However, in my Eclipse, there’re still 3 build errors. The 1st Error is caused by the tag in the pom.xml under “openmrs-webapp”. I’ve searched on Google and tried many ways but can never resolve this error. Please find the screen as below:

And here’s the error message:
