can use the management project as the parent node directly. Example:Because the above practices will cause all projects that inherit this parent node to download the dependent packages configured by this parent node, if some projects do not have to require this dependency package, this dependency package is declared as requiring no automatic download dependencies:Then the project that inherits this parent node is not automatically downloaded:If there is a project to configure this parent node t

The scope of a static local variable is the scope of the code block (the same as the normal local variable), the Link property is no connection, the scope of the global variable is the file scope (and the function is the same), the Link property aspect is an outer join.The second is to modify the global variable
