The original issue is reported here: JBIDE-23631

When importing the DR9 build of the quickstarts into JBDS, you see the following error and warnings:

Errors:

• * JSP Problem: Can not find the tag library descriptor for "http://java.sun.com/jsp/jstl/core" index.jsp /jboss-spring-kitchensink-basic/src/main/webapp/WEB-INF/views line 17

Warnings:

• JSP Problem: Unknown tag (c:choose). index.jsp /jboss-spring-kitchensink-basic/src/main/webapp/WEB-INF/views line 76
• JSP Problem: Unknown tag (c:forEach). index.jsp /jboss-spring-kitchensink-basic/src/main/webapp/WEB-INF/views line 92
• JSP Problem: Unknown tag (c:otherwise). index.jsp /jboss-spring-kitchensink-basic/src/main/webapp/WEB-INF/views line 80
• JSP Problem: Unknown tag (c:when). index.jsp /jboss-spring-kitchensink-basic/src/main/webapp/WEB-INF/views line 77

Note that the quickstarts in the 7.1.x-develop branch import into JBDS with no errors, so I assume this is an issue with the DR9 build of the Maven repository.
