所有 Maven 项目都有一组可用的属性。

project.basedir: The directory that the current project resides in.
project.basedir: 当前项目所在的目录。
This means this points to where your Maven projects resides on your system. It corresponds to the location of the pom.xmlfile. If your POM is located inside /path/to/project/pom.xmlthen this property will evaluate to /path/to/project.
这意味着这指向您的 Maven 项目在您的系统上的位置。它对应于pom.xml文件的位置。如果您的 POM 位于内部，/path/to/project/pom.xml则此属性将评估为/path/to/project.
