Can there be multiple war tasks in build.gradle to generate multiple wars with different dependencies - gradle

Question

I am trying to do similar thing as: Create multiple .WAR files with different dependencies in Gradle
But the solution given in this post is not working. I am using gradle 2.5 to achieve this.
Expectation is to generate 3 different wars as output of the script. I created a simplest project with minimal dependencies. When i execute build.gradle, it just gives me single war named: Test-1.0.war. Test is name of the sample project i created.
Here is build.gradle:
apply plugin: 'java'
apply plugin: 'war'
sourceCompatibility = 1.5
version = '1.0'
task createStandardWar(type: War, dependsOn: classes) {
baseName = 'standard'
destinationDir = file("$buildDir/libs")
classifier = 'Functional'
}
task createStandardWarQasOnly(type: War, dependsOn: classes) {
baseName = 'standard-qas-only'
destinationDir = file("$buildDir/libs")
classifier = 'Functional2'
}
task createStandardWarQasAndLog4J(type: War, dependsOn: classes) {
baseName = 'standard-qas-log4j'
destinationDir = file("$buildDir/libs")
classifier = 'Functional3'
}
task createDists(dependsOn: [createStandardWar, createStandardWarQasOnly, createStandardWarQasAndLog4J])
repositories {
mavenCentral()
}
dependencies {
compile group: 'commons-collections', name: 'commons-collections', version: '3.2'
testCompile group: 'junit', name: 'junit', version: '4.+'
}
test {
systemProperties 'property': 'value'
}
