Please excuse the error

I made a java Library module in Android studio, and there is no problem with Compile, but there is a problem when running;; It's been a few days since Googleing, but I haven't solved it yet ㅠ 구 The result of Googleing is that I couldn't find the jar file at runtime; I don't know even if I listen to it

-------------android gradle---------------------

apply plugin: 'java-library'

repositories { maven { url 'https://oss.sonatype.org/content/repositories/snapshots' } mavenCentral() }

dependencies {

implementation fileTree(include: ['*.jar'], dir: 'libs')

compile 'org.igniterealtime.smack:smack-java7:4.2.3'
compile 'org.igniterealtime.smack:smack-core:4.2.3'
compile 'org.igniterealtime.smack:smack-tcp:4.2.3'
compile 'org.igniterealtime.smack:smack-im:4.2.3'
compile 'org.igniterealtime.smack:smack-extensions:4.2.3'
compile 'xpp3:xpp3:1.1.3.3'

}
