为何package不成功？

[ERROR] Failed to execute goal on project service-twilio: Could not resolve dependencies for project com.example:service-twilio:jar:0.0.1-SNAPSHOT: Failed to collect dependencies at com.example:model:jar:0.0.1-SNAPSHOT: Failed to read artifact descriptor for com.example:model:jar:0.0.1-SNAPSHOT: Could not find artifact com.example:cloud-demo:pom:0.0.1-SNAPSHOT -> [Help 1]

1.首先检查项目的文件路径是否有中文字符。

2.出现这样的错误，是因为自己没有首先对父项目也就是service-xxxx项目进行clean和install ，执行父项目service-xxxx的clean和install，再进行package, 成功解决!
