无法创建 MUnit 测试或套件

Question

当尝试在 Anypoint Studio 中通过右键单击流程然后选择“创建新的 text.xml 套件”来创建 MUnit 测试时，我看到出现以下对话框：

这样做的缺点是不提供任何堆栈跟踪，但是，查看错误日志我可以看到以下堆栈跟踪。

我使用的是 MUnit 1.4.3 版、Anypoint Studio 6.2.5 版和 java 1.8.0_131

有没有其他人遇到过这个问题，可以提出解决方案？

Answer 1

您能否验证您已正确安装并运行 maven ？ 另外，你能检查一下你在 Anypoint Studio 中是否安装了 munit 插件吗？查看帮助菜单>>安装详情>>搜索munit anypoint studio插件

Answer 2

转到任意点导航栏

  ->Help
  ->Install New Softwares
  ->Work with - Munit Update Sites
  ->Install All updates

之后就可以使用了。

Answer 3

我过去也遇到过类似的问题。根据 MuleSoft 支持人员的建议，我的解决方案是：

请尝试创建一个新的工作区，因为工作区有时可能会损坏并产生一些奇怪的错误。

Answer 4

我有类似的问题。我从下面的插件 URL 安装了 Munit

Mule 3 安装插件 URL - http://studio.mulesoft.org/r6/munit 安装后效果很好。

Mule 4 用户可以使用 - http://studio.mulesoft.org/s4/munit
