我已经用cobertura配置了我的项目，而且我是新手。
我想部署mvn网站。因为它是一个多模块项目，我首先做了
mvn site:site
mvn site:stage
直到这里我能够让所有链接正常工作的网站。 但是，当我尝试 mvn site：deploy 时，我收到以下错误
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-site-plugin:3.5.1:deploy (default-cli) on project Myproject: Error uploading site: Error copying directory structure: Could not create destination directory '/./css'. -> [Help 1]
