Mule - 使用 maven 运行时项目构建失败

Question

我在尝试运行 Hello World Mulesoft 项目时遇到了失败，它看起来与我正在运行的 Mulesoft 版本有关，我在 Google 上四处搜索，但无法获得任何信息来帮助解决此问题，这里是构建错误：

知道发生了什么吗？

感谢您的帮助。

Answer 1

Maven 无法找到 transports:mule-transport-file:jar:3.8.4，因为它在您的 pom 中配置的 <repositories> 下的 Mule Maven 存储库中不可用。这是 Public Mule 存储库，但似乎 3.8.4 运行时及其依赖项并未公开，可能仅适用于企业用户。你可以通过浏览存储库自己查看，缺少 JAR：https://repository-master.mulesoft.org/nexus/content/repositories/releases/org/mule/transports/mule-transport-file/3.8.4

您可以使用依赖项可用的 Mule 3.8.1（在您的 pom 中更改 Mule 版本）或配置企业 (EE) 存储库（如果您有适当的许可和访问权限）（请参阅https://docs.mulesoft.com/mule-user-guide/v/3.8/configuring-maven-to-work-with-mule-esb）

*不相关说明：您似乎在 Studio 中运行 Mule EE。 Studio 提供 EE 运行时用于测试目的，因此 Maven 不会（过多地）抱怨缺少 EE 依赖项，但是如果您尝试在 Studio 之外运行 Mule EE，则需要配置 EE 存储库。 *

Answer 2

使用代理详细信息更新 Setting.xml，如果您从组织网络尝试，似乎无法下载所有 jars

Answer 3

我假设这是您的第一个项目。您可以禁用 Maven 以体验 MULE 行为。右键单击该项目，它提供了一个禁用 Maven 的选项。之后你就可以运行你的项目了。
