Jenkins发布时常见异常（持续更新...）

1. Exception when publishing, exception message [Exec exit status not zero. Status [126]

报错日志：

SSH: EXEC: STDOUT/STDERR from command [/app/***/publish.sh] ...
bash: /app/***/publish.sh: Permission denied
SSH: EXEC: completed after 200 ms
SSH: Disconnecting configuration [***] ...
ERROR: Exception when publishing, exception message [Exec exit status not zero. Status [126]]
Build step 'Send build artifacts over SSH' changed build result to UNSTABLE
Finished: UNSTABLE

原因：
Jenkins调用的脚本文件权限不够

解决：
使用chmod增加权限

chmod 777 publish.sh

2. Exception when publishing, exception message [Exec exit status not zero. Status [127]]

报错日志：

SSH: EXEC: STDOUT/STDERR from command [/app/***/publish.sh] ...
bash: /app/***/publish.sh: No such file or directory
SSH: EXEC: completed after 200 ms
SSH: Disconnecting configuration [***] ...
ERROR: Exception when publishing, exception message [Exec exit status not zero. Status [127]]
Build step 'Send build artifacts over SSH' changed build result to UNSTABLE
Finished: UNSTABLE

原因：

脚本文件目录错误

解决：

将Jenkins配置中的脚本目录地址改正确。
这里需要注意一下：当 SSH Server 中配置Remote Directory后，下图中的 Remote directory 填写相对地址；Exec command 填写绝对地址。

3. ERROR: Error cloning remote repo ‘origin’

ERROR: Error cloning remote repo 'origin'
SSH: Current build result is [FAILURE], not going to run.
Finished: FAILURE

原因：
从描述信息来看，是无法拉取远程代码，之前明明是好正常的，怎么突然一下就不行了呢？那你想想，是不是最近负责这个项目的人离职了，O(∩_∩)O哈哈~
这个原因主要是 Git 用户被注销了，无法通过该用户获取 Git 代码。

解决：
从【配置】中，找到配置 Git 远程地址的地方，下图中会报红，将【Credentials】改成自己的用户就可以了。

4. ERROR: Exception when publishing, exception message [Failure]

报错日志：

ERROR: Exception when publishing, exception message [Failure]
Build step 'Send build artifacts over SSH' changed build result to UNSTABLE
Finished: UNSTABLE

原因：

发生这个错误，一般是磁盘空间不足了，这种情况在测试环境比较常见（毕竟生产环境会有监控提醒的）！

解决：

查询磁盘使用情况命令：

df -h

使用删除文件命令，删掉多余日志：

rm -rf [指定文件]
