How to use if else condition in Gradle

Question

Can someone tell me how could I write the if else condition in the gradle script I mean i have two different types of zip files one is LiceseGenerator-4.0.0.58 and other one is CLI-4.0.0.60.My deployment script is working fine but I am using the shell script to do this and I want everything in gradle instead of doing it in the shell script.I want when I am deploying the LicenseGenerator it should deploy in differnet way and if it is CLI then it should deploy in other way.Currently deployall task is doing everyting.If I put if else condition how could I call the task.Please let me know if need any other information

Below is my script

// ------ Tell the script to get dependencies from artifactory ------
buildscript {
    repositories {
      maven {
        url "http://ct.ts.th.com:8/artifactory/libs-snapshot"
         }
    }

    // ------ Tell the script to get dependencies from artifactory ------
    dependencies {
    classpath ([ "com.trn.cm:cmplugin:1.1.118" ])
  }
}

apply plugin: 'com.trn.cm.cmgplugin'

/**
 * The folloing -D parameters are required to run this task
 *  - deployLayer = one of acceptance, latest, production, test
 */
//------------------------------------------------------------------------------------------
// Read the properties file and take the value as per the enviornment.
// 
//------------------------------------------------------------------------------------------
if(!System.properties.deployLayer) throw new Exception ("deployLayer must be set")
def thePropFile = file("config/${System.properties.deployLayer}.properties")
if(!thePropFile.exists()) throw new Exception("Cannot load the specified environment properties from ${thePropFile}")
println "Deploying ${System.properties.jobName}.${System.properties.buildNumber} to ${System.properties.deployLayer}"

// load the deploy properties from the file
def deployProperties = new Properties()
thePropFile.withInputStream { 
    stream -> deployProperties.load(stream) 
} 
// set them in the build environment
project.ext {
  deployProps = deployProperties
  deployRoot = deployProperties["${System.properties.jobName}.deployroot"]
  deployFolder = deployProperties["${System.properties.jobName}.foldername"]
  deployPostInstallSteps = deployProperties["${System.properties.jobName}.postInstallSteps"]
}

task deleteGraphicsAssets(type: Delete, dependsOn: deploy) {
    def dirName = "${deployRoot}"
    delete dirName

    doLast {
        file(dirName).mkdirs()
    }
}


task myCustomTask(dependsOn: deleteGraphicsAssets) << {
    copy {
        from 'deploymentfiles'
        into "${deployRoot}"
    }
}

task cleanTempDir(type: Delete, dependsOn: myCustomTask) {
      delete fileTree(dir: "build/artifacts", exclude: "*.zip")
  }

task unzipArtifact(dependsOn: cleanTempDir) << {
  file("${buildDir}/artifacts").eachFile() { 
    println "Deploying ${it}"
   // ant.mkdir(dir: "${deployRoot}/${deployFolder}")
    ant.unzip(src: it, dest: "${deployRoot}")
  }
}

task setPerms( type: Exec, dependsOn: unzipArtifact) {
  workingDir "${deployRoot}"
  executable "bash"
  args "-c", "dos2unix analyticsEngine.sh"
  args "-c", "chmod u+x analyticsEngine.sh && ./analyticsEngine.sh"
 }

 task deployAll(dependsOn: setPerms){}

I used in below way it is working fine

  // ------ Tell the script to get dependencies from artifactory ------
    buildscript {
        repositories {
          maven {
            url "http://c.t.th.com:8/artifactory/libs-snapshot"
             }
        }

        // ------ Tell the script to get dependencies from artifactory ------
        dependencies {
        classpath ([ "c.t.c:cmgin:1.1.118" ])
      }
    }

    apply plugin: 'com.t.c.cmlugin'

    /**
     * The folloing -D parameters are required to run this task

    if(!System.properties.deployLayer) throw new Exception ("deployLayer must be set")
    def thePropFile = file("config/${System.properties.deployLayer}.properties")
    if(!thePropFile.exists()) throw new Exception("Cannot load the specified environment properties from ${thePropFile}")
    println "Deploying ${System.properties.jobName}.${System.properties.buildNumber} to ${System.properties.deployLayer}"

    // load the deploy properties from the file

    task deployAll(dependsOn: zipDeployment){}
