能否请您告诉我可能的解决方法.
Can you please tell me possible resolution.
推荐答案
根据文档，使用 CVS 在使用pserver方法时使用以下格式:
According to the documentation, the SCM url when using CVS uses the following format when using the pserver method:
scm:cvs<delimiter>pserver<delimiter>[username[<delimiter>password]@]servername[<delimiter>port]<delimiter>path_to_repository<delimiter>module_name
您的末尾缺少模块名称(因此实际上是无效的)，您的网址应类似于(假设change1t是用户名):
Yours is missing the module name at the end (and is thus indeed invalid), your url should be something like (assuming change1t is the username):
scm:cvs:pserver:change1t@aukjupcx:/home/cvs/cvsroot:module_name
