你能告诉我可能的解决方案吗？

【问题讨论】：

标签： cvs maven maven-scm

【解决方案1】：

根据文档，使用CVS时的SCM url在使用pserver方法时使用如下格式：

scm:cvs<delimiter>pserver<delimiter>[username[<delimiter>password]@]servername[<delimiter>port]<delimiter>path_to_repository<delimiter>module_name

您的最后缺少模块名称（因此确实无效），您的网址应该类似于（假设 change1t 是用户名）：

scm:cvs:pserver:change1t@aukjupcx:/home/cvs/cvsroot:module_name

你是一台机器，先生。我点击的每一个问题，都有。我向你致敬。
@warandpeace LOL :) 我确实在一些话题上很活跃。
