Question

我正在尝试使用Jangaroo将FLEX转换为HTML 5和JavaScript。为了做到这一点，我需要使用Maven，并且在编译Maven（mvn compile）时，我会遇到一些错误。错误显示如下。 anoyone可以帮助我吗???

Maven尝试从其中央Maven存储库（或您在Maven设置或pom.xml中指定的任何其他存储库）下载构建所需的所有内容。错误＆＃34;连接超时＆＃34;表示在IP地址199.27.74.129下（当前）无法从您的计算机访问repo.maven.apache.org。您有网络（配置）问题，或者当您尝试编译时服务器确实关闭了。执行以下命令时的输出是什么？

ping repo.maven.apache.org

在您编译项目一次之后，可以使用Maven命令行开关-o离线重新编译它（除非您添加需要下载的新依赖项）。

不过，你应该真正更新到更新的Jangaroo版本。截至目前，jangaroo-maven-plugin和jangaroo-runtime为1.0.2，所有其他jangaroo-libs（jangaroo-browser，jooflash等为1.0.3）
