Duplicate name in Manifest: SHA1-Digest

Duplicate name in Manifest: SHA1-Digest

在运行有fat jar打包的JAR文件时控制台出现各种警告:
WARNING: Duplicate name in Manifest: SHA1-Digest.
Ensure that the manifest does not have duplicate entries, and
that blank lines separate individual sections in both your
manifest and in the META-INF/MANIFEST.MF entry in the jar file.

问题原因：
在MANIFEST.MF文件中，有多个SHA1-Digest，导致控制台报错
解决方法:
在用fat jar打包时，取消“merge individual-sections of all MANIFEST.MF files”选项，然后其他操作照旧，这样就可以了
