在 Ubuntu Server 18.04 上，我创建了一个 Maven 项目框架，如下所示，我只是想让它编译。<​​/p> 

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

运行 mvn compile 就可以了。但是运行 mvn test 失败并出现错误

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.20.1:test (default-test) on project my-app: Execution default-test of goal org.apache.maven.plugins:maven-surefire-plugin:2.20.1:test failed.: NullPointerException -> [Help 1]

两个问题:

  1. 可能是什么原因造成的？

  2. 据我了解，archetype:generate是一个帮助创建模板 Maven 项目的官方插件。是否有其他方法可以轻松创建骨架 Maven 项目？

最佳答案

您的问题是由 maven-surefire 中的这个错误引起的:bugzilla.redhat.com/show_bug.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

关于java - Maven 原型(prototype) : org. apache.maven.plugins :maven-surefire-plugin:2. 20.1 :test failed. : NullPointerException，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/53258224/
