Migrating from existing dynamic web project to gradle? - eclipse

Question

I have a following structure .
I am constructing build.gradle by copy-paste from numerous sources..
buildscript {
repositories {
jcenter()
mavenCentral()
}
dependencies {
classpath 'com.bmuschko:gradle-tomcat-plugin:2.2.2'
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'war'
apply plugin: 'com.bmuschko.tomcat'
webAppDirName = 'WebContent'
repositories {
jcenter()
mavenCentral()
}
sourceSets {
main {
// where does the Java source code live?
java {
srcDir 'src'
}
// where do classpath resources like *.properties files live?
resources {
srcDir 'src/main/resources'
}
}
}
sourceCompatibility = 1.7
targetCompatibility = 1.7
dependencies {
testCompile("junit:junit")
compile fileTree(dir: 'WebContent/WEB-INF/lib', include: ['*.jar'])
String tomcatVersion = '7.0.52'
tomcat "org.apache.tomcat.embed:tomcat-embed-core:${tomcatVersion}"
tomcat "org.apache.tomcat.embed:tomcat-embed-logging-juli:${tomcatVersion}"
tomcat("org.apache.tomcat.embed:tomcat-embed-jasper:${tomcatVersion}") {
exclude group: 'org.eclipse.jdt.core.compiler', module: 'ecj'
}
}
task wrapper(type: Wrapper) {
gradleVersion = '2.3'
}
tomcat {
contextPath = '/'
}
when I run gradle tomcatRun, I see the following output
02:49:58.819 [QUIET]
[com.bmuschko.gradle.tomcat.embedded.BaseTomcatServerImpl$AfterStartEventLifecycleListener]
Started Tomcat Server 02:49:58.820 [QUIET]
[com.bmuschko.gradle.tomcat.embedded.BaseTomcatServerImpl$AfterStartEventLifecycleListener]
The Server is running at http://localhost:8080
Building 75% > :tomcatRun
But when I connect to http://localhost:8080 I see either 404 error or blank page..
