- 把aspose-slides-21.10-jdk16.jar后缀改成rar/zip等能解压的格式，解压为aspose-slides-21.10-jdk16（文件名随意）
- 把刚刚生成文件替换到com.aspose.slides中
- 删除aspose-slides-21.10-jdk16.jar中META-INF中的.RSA和.SF后缀的文件
- 将生成的jar文件放到maven库中，mvn install:install-file -Dfile="C:\Users\zzy1998\Desktop\text\aspose-slides-21.10-jdk16.jar" -DgroupId=com.aspose -DartifactId=aspose-slides -Dversion=21.10 -Dpackaging=jar
