Unit test failure on building of Jackson-Core Version 2.11.2
问题
在手动构建使用最新版本2.11.2的jackson-core模块的过程中，我在单元测试中遇到了一个错误；我猜测这可能是因为我的笔记本电脑上的设置问题。
执行的步骤：
- Java版本 -> 1.8
- 克隆jackson-core仓库
git checkout tags/jackson-core-2.11.2mvn package
结果：
[INFO] 运行测试: 3个，失败: 0个，错误: 0个，跳过: 0个，耗时: 0.004秒 - 位于 com.fasterxml.jackson.core.type.TypeReferenceTest

问题：
我想知道在笔记本电脑上可能出了什么设置问题，导致单元测试失败？

查看他们的代码，特别是那个特定的单元测试，他们将\n视为Eol（行尾结束符）进行比较。
我认为你看到的错误可能与你所使用的操作系统有关，因为在不同操作系统之间可能会有差异。
英文:
Looking at their code, specially at the specific unit test, they are comparing \n as the Eol.
I believe the error you are seeing could be related to the OS you are running on as it might differ between them.
