Answer 1

As the error message suggests you are not excluding the META-INF/LICENSE file which exists in more than one of your dependencies

packagingOptions {
     exclude 'META-INF/NOTICE' 
     exclude 'META-INF/LICENSE'
     exclude 'META-INF/notice'
     exclude 'META-INF/notice.txt'
     exclude 'META-INF/license'
     exclude 'META-INF/license.txt'
}

Answer 2

try this it works in my case

Add below text on build.gradle file solve problem

packagingOptions {
    exclude  'jsr305_annotations/Jsr305_annotations.gwt.xml'
    exclude  'build-data.properties'
    exclude 'META-INF/DEPENDENCIES.txt'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/notice.txt'
    exclude 'META-INF/license.txt'
    exclude 'META-INF/dependencies.txt'
    exclude 'META-INF/LGPL2.1'
 }
