我有一个Android（Java）项目，并且迁移到AndroidX之后，我收到以下错误(d8 errors)：
Program type already present: com.enterprisedt.BaseIOException
请注意，gradle同步正常发生。该错误仅在设备编译时出现。最奇怪的是，它只会在我为Android 4设备进行编译时发生。 尝试针对Android 5+进行编译时，编译成功且应用程序运行平稳。

我提到的3个库（激活，邮件，edtftpj）必须同时存在于lib和project中，因为它们实际上已被使用。
我已经尝试过：
packagingOptions {
exclude 'com/sun/mail/dsn/mailcap'
exclude 'dsn.mf'
exclude 'javamail.charset.map'
exclude 'javamail.default.address.map'
exclude 'javamail.default.providers'
exclude 'javamail.imap.provider'
exclude 'javamail.pop3.provider'
exclude 'javamail.smtp.address.map'
exclude 'javamail.smtp.provider'
exclude 'mailcap'
exclude 'mimetypes.default'
exclude 'mailcap.default'
exclude 'com.enterprisedt.BaseIOException'
exclude 'javax.activation.*'
}
有人可以帮助我吗？
