Maven Surefire 插件丢失？

Question

所以我遇到了问题，我正在按照教程 Working with Custom Content types in Alfresco 进行操作但当我尝试安装该程序时遇到 Maven 问题。它告诉我 Maven Surefire 插件存在问题，如下所示:

问题是我没有这样的directory in my project正如您在 中看到的。那么我在哪里可以找到它或使用 maven 生成它？

感谢您的帮助!

这是问题的根源:在尝试进行测试时，surefire 插件尝试实例化 JVM 但失败，因为它无法分配足够的内存。缺少 target\surefire 目录只是该故障的结果，target 目录在故障后被清理。

您应该按照优先顺序尝试:

• 为运行测试的 JVM 提供更多可用内存。这可以通过 increasing your available swap memory 解决例如

• 限制测试 JVM 使用的内存。看一下surefire插件配置，可以设置JVM parameters

• 要跳过所有测试:使用 mvn install -DskipTests ；当然，执行过程不再一样了
