【Arthas 】Can not find Arthas under local: /root/.arthas/lib 解决办法

报错

[INFO] JAVA_HOME: /opt/java/openjdk
[INFO] arthas-boot version: 4.0.4
[INFO] Found existing java process, please choose one and input the serial number of the process, eg : 1. Then hit ENTER.

  [ERROR] Can not read arthas version from: https://arthas.aliyun.com/api/latest_version
  [ERROR] Can not find Arthas under local: /root/.arthas/lib and remote repo mirror: aliyun
  [ERROR] Unable to download arthas from remote server, please download the full package according to wiki: https://github.com/alibaba/arthas

原因

原来arthas-boot.jar并不是全量包，它会在启动的时候先去阿里Maven仓库下载一些jar包依赖；如果Maven下载失败，那么它会检查本地是否有jar包依赖文件，例如日志：

[ERROR] Can not find Arthas under local: /root/.arthas/lib

解决办法

下载全量包
https://arthas.aliyun.com/doc/install-detail.html#%E5%85%A8%E9%87%8F%E5%AE%89%E8%A3%85

然后解压复制到容器里面进行排查即可
