configurations {
    all*.exclude group : 'xpp3', module : 'xpp3'

}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation files('libs/json-simple-1.1.1.jar')
    implementation files('libs/xmlpull-1.1.3.1.jar')

    compile group: 'org.igniterealtime.smack', name: 'smack-core', version: '4.2.3'
    compile group: 'org.igniterealtime.smack', name: 'smack-tcp', version: '4.2.3'
    compile group: 'org.igniterealtime.smack', name: 'smack-android', version: '4.2.3'
    compile group: 'org.igniterealtime.smack', name: 'smack-im', version: '4.2.3'
    compile group: 'org.igniterealtime.smack', name: 'smack-java7', version: '4.2.3'

    compile group: 'org.jxmpp', name: 'jxmpp-stringprep-libidn', version: '0.5.0'

}

sourceCompatibility = "1.8"
targetCompatibility = "1.8"

 

이렇게 만들었구 다음의 에러가 발생합니다.
