我尝试开发一个jenkins（又名hudson）插件，并遵循教程，并在mvn-cpu-hpi:create命令后生成源代码树。
而当我做“mvn包”时，它会报告如下错误
[INFO] Building Unnamed - com.example.jenkins:redmine2:hpi:1.0-SNAPSHOT
[INFO] task-segment: [clean]

Reason: Error getting POM for org.apache.maven.plugins:maven-enforcer-plugin from the repository: Failed to resolve artifact, possibly due to a repository list that is not appropriately equipped for this artifact s metadata.

from the specified remote repositories:
nexus (http://maven.nexus.local:8888/nexus/content/groups/public)
for project org.apache.maven.plugins:maven-enforcer-plugin
从我的nexus服务器上，它有maven enforcer插件：只有1.0版本，但这个依赖关系默认是从jenkins生成的，有人能帮我解决吗？
- (How) Can I change to plugin-1.0 version.
- what can I add in nexus server
我只是对maven有基本的了解。
