Before setting permissions, it is recommended to create a separate repository for your project group. It is convenient to assign permissions to the group.

Ideas : Customize privileges and roles for anonymous; privileges can be set according to repository targets.
3.1. Setting repository targets
: Use it to configure which directories of artifacts can be accessed.
     a. Add a new repository targets
        name: it is best to take a meaningful name

        Pattern Expression: Set the path of articfact that can be matched according to wildcards
         .*/com/some/company/.* --Can match "com.some.company" as groupid, The artifactid contains               
         ^/com/some/company/* -- the artifact of the path starting with com/some/company
        For example: I want to match all the artifacts under SNAPSHOT of the company. It can be configured as:
              .*/com/xxx/companyname /xxx/.*SNAPSHOT/.*
      b. Click the "Add" button to add pattern expression to patterns
c. You can add multiple Pattern Expressions to set multiple artifacts

3.2. Set
     the role of routing: configure which directories are through routing Which can be accessed through the repository path, and which ones cannot be accessed through the repository path.
