Answer 1

I was facing the same problem wis gradle tomcat plugin. I updated the tomcat version to 8 and it worked.

plugins {
    id "com.bmuschko.tomcat" version "2.2.2"
    id "java"
    id "eclipse"
    id "idea"
    id "war"
}


dependencies {
    providedCompile ('javax.servlet:javax.servlet-api:3.1.0')
    providedCompile ('javax.servlet.jsp:jsp-api:2.2')
    compile ('org.springframework:spring-webmvc:4.2.1.RELEASE')

    def tomcatVersion = '8.0.27'
    tomcat "org.apache.tomcat.embed:tomcat-embed-core:${tomcatVersion}",
            "org.apache.tomcat.embed:tomcat-embed-logging-juli:${tomcatVersion}",
            "org.apache.tomcat.embed:tomcat-embed-jasper:${tomcatVersion}"

}
