我正在尝试集成Atlassian Clover插件以使用我现有的Maven 3项目。我也在使用Nexus 2.6.3。 e.g。
mvn clover2:setup test clover2:aggregate clover2:clover
产生错误：
[ERROR] Failed to execute goal com.atlassian.maven.plugins:maven-clover2-plugin:3.2.0:instrumentInternal (default-cli) on project hpcmom: Execution default-cli of goal com.atlassian.maven.plugins:maven-clover2-plugin:3.2.0:instrumentInternal failed: Plugin com.atlassian.maven.plugins:maven-clover2-plugin:3.2.0 or one of its dependencies could not be resolved: The following artifacts could not be resolved: org.apache.ant:ant:jar:1.8.4, com.cenqua.clover:clover:jar:3.2.0: Could not find artifact org.apache.ant:ant:jar:1.8.4 in nexus (http://olympus:8081/nexus/content/groups/public) -> [Help 1]
这不是真的，我可以在Central中正确地看到并手动下载所谓的缺失工件org.apache.ant:ant:jar:1.8.4，甚至从远程存储库选项卡视图中我也可以找到所需的工件。
我的版本也会导致以下错误：

答案 0 :(得分：1)
确保中央存储库是您的公共组的一部分。查看配置并通过浏览Nexus中的远程仓库进行检查，以确保没有网络问题阻止Nexus连接到Central repo以下载这些jar。
一旦你确认强制更新，因为Maven可能已经缓存了在本地仓库中找不到组件的事实。使用
mvn -U clover2:setup test clover2:aggregate clover2:clover
