adding these lines helped me.

shadowJar {
    // Filtering shadow jar contents by file pattern.
    exclude 'schemaorg_apache_xmlbeans/attribute/**'
    exclude 'schemaorg_apache_xmlbeans/attributegroup/**'
    exclude 'schemaorg_apache_xmlbeans/element/**'
    exclude 'schemaorg_apache_xmlbeans/identityconstraint/**'

    exclude 'schemaorg_apache_xmlbeans/modelgroup/**'
    exclude 'schemaorg_apache_xmlbeans/namespace/**'
    exclude 'schemaorg_apache_xmlbeans/src/**'
    exclude 'schemaorg_apache_xmlbeans/system/sXML*/**'
    exclude 'schemaorg_apache_xmlbeans/system/s8C3F193EE11A2F798ACF65489B9E6078/**'

    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/maven/**'

    // these are only needed when handling Visio files, remove it if you would like to use Visio support
    dependencies {
        exclude(dependency('com.github.virtuald:curvesapi'))
        exclude(dependency('commons-codec:commons-codec'))
    }

    // Relocate javax dependencies so Android does not choke
    relocate 'javax.xml.namespace', 'org.apache.poi.javax.xml.namespace'
    relocate 'javax.xml.stream', 'org.apache.poi.javax.xml.stream'
    relocate 'javax.xml.XMLConstants', 'org.apache.poi.javax.xml.XMLConstants'

If the solution in the selected answer does not fix your problem, try adding

    exclude 'META-INF/ASL2.0'

as well. Or basically, identify the name of the duplicate file and exclude it. The addition above fixed the issue for me.
