java - maven-ant-run 插件由于缺少类而失败

Question

早些时候我使用 Maven 存储库下载所有工件，因此我的项目构建成功。但是，当我删除我的本地存储库并将我的人工制品制作为 Maven 站点的镜像时......我在使用 Maven 3.0.4 构建时遇到此错误:

NFO] ------------------------------------------------------------------------

我检查了 maven-antrun-plugin 的 jar，它有 Ant-run 类。也在另一个 jar org.apache.ant1.8.1 jar 这个类 org/apache/tools/ant/BuildException 也存在，但我仍然收到此错误..我无法解决此问题..谢谢。

也许 m2/repository/org/apache/ant/ant/1.8.1/ant-1.8.1.jar 文件已损坏。您应该删除 m2/repository/org/apache/ant/ant/1.8.1 目录并重试。
