   1. Install nexus as a service by running the following command:

      If you do not provide a name, the service is named nexus.
   2. Start Nexus by running the following command:

      nexus.exe /start

4. Log into the Talend Artifact Repository Web application (default login information: admin/Talend123). Make sure you have the relevant rights to access the release and snapshot repositories.

   2. On the top of the right panel, click Create role > Nexus role to open the Create Role view.
   3. Create a role nx-view-custom-libs-browse and assign privileges nx-repository-view-maven2-talend-custom-libs-release-browse and nx-repository-view-maven2-talend-custom-libs-snapshot-browse to it.
      
   4. In the left panel of the Talend Artifact Repository Web application, select Security > Users.
   5. Click the user talend-updates-admin to open its details view.
   6. Edit the user by assigning the newly created role nx-view-custom-libs-browse to it.
      
   7. Execute the following commands in Curl or Postman to validate the permissions assigned to the user talend-updates-admin, where <password> represents the password of the user and <nexus_url> represents the URL of the Talend Artifact Repository Web application.

      # Search talend-custom-libs-release
      curl -k -u "talend-updates-admin:<password>" "<nexus_url>/service/rest/v1/search?repository=talend-custom-libs-release&group=xml-apis"
      
      # Search talend-custom-libs-snapshot
      curl -k -u "talend-updates-admin:<password>" "<nexus_url>/service/rest/v1/search?repository=talend-custom-libs-snapshot&group=org.talend.libraries"

      The corresponding items should be returned in the result.
