The container 'Maven Dependencies' references non existing library - STS

Question

I'm using win8 previously I had been running Eclipse Juno on my pc but from now on I wanted to start using STS, I am getting the below error as soon as I create a new project. I deleted my .m2 folder and everything related to Eclipse in order to start over from scratch still didn't work, I've ran out of ideas. Any advice???

Can not find the tag library descriptor for "springframework.org/tags" index.jsp /app/src/main/webapp line 6 JSP Problem

Answer 1

So I get you are using Eclipse with the M2E plugin. Try to update your Maven configuration : In the Project Explorer, right-click on the project, Maven -> Update project.

If the problem still remains, try to clean your project: right-click on your pom.xml, Run as -> Maven build (the second one). Enter "clean package" in the Goals fields. Check the Skip Tests box. Click on the Run button.

Edit: For your new problem, you need to add Spring MVC to your pom.xml. Add something like the following:

<dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-webmvc</artifactId>     <version>4.0.0.RELEASE</version> </dependency> 

Maybe you have to change the version to match the version of your Spring framework. Take a look here:
