问题：java版本引起mailR包没法运行
## 出现： Error in .jnew("org.apache.commons.mail.MultiPartEmail") : java.lang.NoClassDefFoundError: javax/activation/DataSour
### 解决方法：
1. 下载 jar文件：
https://mvnrepository.com/artifact/javax.activation/javax.activation-api/1.2.0
https://mvnrepository.com/artifact/com.sun.activation/javax.activation/1.2.0
2.system.file("java", package = "mailR") 找到安装包位置 C:\Users\xx\Documents\R\win-library\4.0\mailR\java\
3. 将下载的两个文件copy到文件夹下；
4. 重启rstudio即可。
