Question

我使用的是wso2 EM2.2.0Beta，请参考下面的错误控制台。当我运行maven安装时，我遇到了maven程序集插件问题。

所以请告诉我为什么会发生这种情况？并提出了一些解决这个问题的建议。

如果您想要构建WSO2 EMM2.2.0Beta，请遵循以下步骤。

1. 克隆产品-emm回购git clone https://github.com/wso2/product-emm.git
2. 查看v2.2.0-BETA标记。git checkout v2.2.0-BETA
3. 从根部开始构建。转到项目根文件夹并发出mvn clean install

如果您只想要产品zip，您可以为它构建分发模块，然后转到项目根->模块、->distribution文件夹并从那里发出mvn clean install。您可以在distribution/target文件夹中找到构建压缩文件。

好像你在支行。在emm beta标记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中的某些资源，而您的计算机未能连接到internet上的资源。如果您真的想要构建主分支(2.2.0-快照)，只需检查您的internet连接或防火墙阻塞。
