我正在尝试安装第一个出现在here 的 Ninja Web 框架应用程序，但我收到了失败的测试错误。我的java版本是

$ java -version

Java(TM) SE Runtime Environment (build 1.7.0_67-b01)
Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode)

我的 Maven 版本是

$ mvn3 -version
Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 07:51:28-0600)

关于什么是错误的以及如何解决它的任何想法？

【问题讨论】：

你看到这部分了吗Ninja injector 无法生成。请检查日志以了解更多错误？日志中有什么内容吗？

是的，日志中出现了Ninja注入器错误：Tests in error: testGetIndex(controllers.ApiControllerDocTesterTest): java.lang.NullPointerException: Ninja injector cannot be generated。请检查日志以了解更多错误。 testGetIndex(controllers.ApiControllerDocTesterTest) testGetHelloWorldJson(controllers.ApiControllerDocTesterTest): java.lang.NullPointerException: Ninja injector 无法生成。请检查日志以了解更多错误。 testGetHelloWorldJson(controllers.ApiControllerDocTesterTest)

你可以试试 Maven 3.1 吗？我认为 Maven 3.0 有一些问题...

【参考方案1】：

应该可以正常工作。造成麻烦的一件事是 Maven 3.0。您可以尝试使用 Maven 3.1（或 3.2）吗？这应该可以解决它。
