Errors while using both Spring Data Hadoop + Spring MVC

Question

I just started with Spring and Hadoop. I had the following build.gradle which worked fine:

dependencies {
    compile 'org.springframework:spring-webmvc:4.0.6.RELEASE'
    compile 'jstl:jstl:1.2'
    providedCompile 'javax.servlet:servlet-api:2.5'
}

However, when adding

compile 'org.springframework.data:spring-data-hadoop:2.1.2.RELEASE'

to the dependencies, my app can no longer displayed the JSP... I got the error:

javax.servlet.ServletException: java.lang.AbstractMethodError: javax.servlet.jsp.JspFactory.getJspApplicationContext(Ljavax/servlet/ServletContext;)Ljavax/servlet/jsp/JspApplicationContext;
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:273)

I am using Tomcat 7.0.61, with Eclipse Juno (version 4.2.0).

After some research, I found that I should add dependencies exclusions, but which ones? Because I only have two dependencies (sping mvc and spring data hadoop) but I can't exclude any of them.

I am very new with Gradle too.
Thank you for your help.

Answer 1

I was having dependencies problem with Tomcat. I added on top of my build.gradle file:

configurations {
    all*.exclude group: 'tomcat', module: 'jasper-runtime'
}

This solved the problem.
