Jackson-Core 版本 2.11.2 的单元测试失败

Question

在使用最新版本 2.11.2 手动构建 jackson-core 模块的过程中，我在单元测试中遇到错误；我假设这是由于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-2.11.2
mvn package

结果：

问题：我想知道笔记本电脑上的什么设置可能导致单元测试失败？

Answer 1

查看他们的 code, specially at the specific unit test，他们正在将 \n 与 Eol 进行比较。我相信您看到的错误可能与您运行所在的 OS 有关，因为它们之间可能有所不同。
