Maven-无法在项目上执行goal org.apache.Maven.plugins:Maven程序集plugin:2.4:single（1-pre-dist）

我正在使用wso2 emm 2.2.0测试版，请参阅下面的错误控制台。当我运行maven安装时，我遇到了maven汇编插件问题

所以请让我知道为什么会这样？并给出一些解决这个问题的建议

如果您想构建WSO2 EMM 2.2.0测试版，请遵循以下步骤

克隆产品emm repo

git克隆https://github.com/wso2/product-emm.git

签出v2.2.0-BETA标签。

git checkout v2.2.0-BETA版

从根pom构建。转到项目根文件夹并发布

mvn清洁安装

如果您只需要产品zip，您可以为其构建分发模块，转到project root->modules->distribution文件夹，然后从那里发布

mvn clean install

。您可以在

distribution/target

文件夹中找到构建zip文件

看来你是在主分行。在emm beta标签创建之后，添加了失败的maven目标。失败的原因是，在构建时它试图连接到internet上的某些资源，而您的计算机无法连接到internet上的这些资源。如果您真的想构建主分支（2.2.0-SNAPSHOT），只需检查您的internet连接或防火墙阻止。

您是否要从根pom构建2.2.0测试版标记？是的，但我不知道。怎么做？我想构建产品压缩包。您可以克隆产品emm repo和checkout v2.2.0-BETA标记，并从根文件夹执行mvn clean install。Ya。。我们也试过了，但是我们得到了类似

无法在项目wso2emm上执行目标com.google.code.maven配置处理器插件：配置处理器maven插件：2.6:process（添加自定义安全头）：配置处理期间出错：java.net.ConnectException:连接超时

我可以毫无问题地构建。您使用的java版本和maven版本是什么？
