Intellij + Gradle + SpringLoaded + Tomcat

Question

I'm developing Spring rest service using Gradle, Intellij, and Tomcat. I want to reload my changes without redeploying, so I use SpringLoaded. But it doesn't reload my project. Even hot swap doesn't work. Here is my build.gradle:

def group = 'com.expecker'
version '1.0-SNAPSHOT'
apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'maven'
sourceCompatibility = 1.8
targetCompatibility = 1.8
def springVersion = '4.0.0.RELEASE'
def hibernateVersion = '5.0.7.Final'
def junitVersion = '4.11'
repositories {
    mavenCentral()
}
dependencies {
    testCompile group: 'junit', name: 'junit', version: junitVersion
    compile "org.springframework:spring-core:$springVersion"
    compile "org.springframework:spring-web:$springVersion"
    compile "org.springframework:spring-webmvc:$springVersion"
    compile "org.springframework:spring-orm:$springVersion"
    compile "org.springframework:spring-jdbc:$springVersion"
    compile "org.springframework:spring-tx:$springVersion"
    compile "org.springframework:spring-orm:$springVersion"
    compile "org.springframework:spring-context:$springVersion"
    compile 'javax.servlet:javax.servlet-api:3.1.0'
    compile 'jstl:jstl:1.2'
    compile 'javax.servlet.jsp:jsp-api:2.2'
//  compile 'org.codehaus.jackson:jackson-mapper-asl:1.9.13' it seems like this library isn't compatible with spring 4.1.x
    compile 'com.fasterxml.jackson.core:jackson-databind:2.6.4'
    compile "org.hibernate:hibernate-core:$hibernateVersion"
    compile "org.hibernate:hibernate-entitymanager:$hibernateVersion"
    compile 'commons-dbcp:commons-dbcp:1.4'
    //compile('org.springframework:springloaded:1.2.5.RELEASE')
}
buildscript {
    repositories { jcenter() }
    dependencies {
        classpath 'org.springframework:springloaded:1.2.5.RELEASE'
    }
}
apply plugin: 'idea'
idea {
    module {
        inheritOutputDirs = false
        outputDir = file("$buildDir/classes/main/")
    }
}
/*

gradle.buildFinished { buildResult ->
    println 'Building pom.xml...'
    pom {
        project {
            groupId "${group}"
            artifactId 'app'
            version "${version}"
            packaging 'war'
        }.withXml {
            asNode().appendNode('profiles').
                    appendNode('profile').with {
                appendNode('id', 'openshift')
                appendNode('build').with {
                    appendNode('finalName', 'expecker')
                    appendNode('plugins').appendNode('plugin').with {
                        appendNode('artifactId', 'maven-war-plugin')
                        appendNode('version', '2.1.1')
                        appendNode('configuration').with {
                            appendNode('outputDirectory', 'deployments')
                            appendNode('warName', 'expecker')
                        }
                    }
                }
            }
        }
    }.writeTo("pom.xml")}

in my Tomcat configuration I have vm option -javaagent:|here is my path to springloaded.jar| -noverify. I chose exploded artifact on deployment tab.

As you can see, I tried to include my springloaded jar to classpath (I don't know why it's needed, I saw it in some articles). I tried to add this jar as a compile dependency, but then I can't build the project. Also I tried to not include it, only set in vm options. Here are some my observations:

• simple Hot swap doesn't work with springloaded agent, but works without it
• It looks like Tomcat use \out\artifacts\expecker\exploded\expecker-1.0-SNAPSHOT.war\ folder, but when I do make project, changes are reflected only with \build\ folder.

Could anyone help me?

My fault, spring loaded doesn't support adding of new classes. So, actually, everything works as expected.
