Android javaMail mergeDebugJavaResource FAILED解决

Java mail 引入这两个jar之后

   implementation 'com.sun.mail:android-mail:1.6.7'implementation 'com.sun.mail:android-activation:1.6.7'

build直接报错

解决办法

需要在app的build.gradle的android{}里面增加 packagingOptions{} ，内容参考报错日志即可

    packagingOptions {exclude 'META-INF/NOTICE.md'exclude 'META-INF/LICENSE.md'}
