这是因为您的包中包含多个包含META-INF/mailcap.default的依赖项。因此,您只需添加META-INF/mailcap.default行,即可使用pickFirst中的一个。像这样:

packagingOptions {
    // use only one
    pickFirst 'META-INF/mailcap.default'

    pickFirst 'META-INF/LICENSE.txt'
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/license.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/notice.txt'
    exclude 'META-INF/ASL2.0'
}
