技术支持项目

问题：在技术支持中遇到过以下问题，需要注意：

用户在pinpoint的fatjar中通过压缩工具打开jar包，然后拖放pinpoint-apusic-plugin-2.1.3-SNAPSHOT.jar这个插件进去之后，通过 java -jar 启动fatjar时候，报以下错误：
Exception in thread "main" java.lang.IllegalStateException: Failed to get nested archive for entry BOOT-INF/L1b/pinpoint-apusic-plugin-2.1.3-SNAPSHOT.jar

解决：

需要先解压fatjar，然后添加新的jar包进去后，再进行打包。

1. jar -xvf xxx.jar
2. jar -cvfM0 xxx.jar -C xxx/ .
