运行由fat jar打包后的jar文件出现警告的处理方法

在运行有fat jar打包的JAR文件时控制台出现各种警告:

008-12-2 8:55:20 java.util.jar.Attributes read

警告: 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.

警告: 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
