Maven原型：org。阿帕奇。专家插件：maven surefire插件：2.20.1：测试失败：空指针异常

Question

在Ubuntu服务器18.04上，我创建了一个框架Maven项目，如下所示，我只是想编译它。

mvn archetype:generate \
-DgroupId=com.mycompany.app \
-DartifactId=my-app \
-DarchetypeArtifactId=maven-archetype-quickstart \
-DinteractiveMode=false \
-DarchetypeVersion=1.3

运行mvn编译可以。但运行mvn测试失败，出现错误

[错误]无法执行目标组织。阿帕奇。专家插件：maven surefire插件：2.20.1:project my app上的测试（默认测试）：目标组织的执行默认测试。阿帕奇。专家插件：maven surefire插件：2.20.1：测试失败：NullPointerException-

两个问题：

>

这可能是什么原因造成的？

据我所知，原型：生成是一个官方插件，有助于创建模板Maven项目。有其他方法可以轻松创建骨架Maven项目吗？

您的问题是由maven surefire中的这个bug引起的：bugzilla。红帽子。com/show_错误。cgi？id=1572708

将版本更新到maven-surefire-2.21.0-1或更高版本应该可以解决您的问题
