concordion - Concordion 无法复制资源（突然）

问题描述

有点奇怪，但突然之间（例如，我的验收测试套件运行良好，而我正忙于做一些不相关的*单元测试），当我开始在测试运行中复制资源失败时。

Failed to copy /org/demo/foo/../../../concordion.css to target [Resource: /org/demo/foo/../../../concordion.css]

    ... 43 more

我在 IntelliJ IDEA 和终端运行 gradle 中得到了这个。

我的测试都以类似的东西开始：

@RunWith(ConcordionRunner.class)
@ConcordionResources(value = { "../../../concordion.css" })
public class Index {
}

...并且该.css文件始终位于其所在的位置（在源代码树中）。在重建之前，我检查了打开的把手并清理了所有东西。文件夹权限似乎很好。有问题的/var文件夹确实是空的。

有任何想法吗？

*我认为

更新：在 Mac 和 Linux 上，如果您删除/var/folders/../concordion或/tmp/concordion（分别），它将重现问题。

解决方案

问题是 Concordion 的FileTarget#createOutputStream(Resource)方法无法创建OutputStream用于写入资源的资源。

假设您的夹具在a.b.c包中，Concordion 正在尝试OutputStream为该文件创建一个文件"<concordion.output.dir>/a/b/c/../../../concordion.css"（<concordion.output.dir>concordion 输出目录在哪里）。如果该"<concordion.output.dir>/a/b/c/"文件夹尚不存在，则会失败 - Java 似乎不会自动“规范化”删除“ ..”的路径。

解决方案是规范化路径（可能使用Path.normalize()）。

要解决此问题，您可以更新到即将推出的 2.2.1 版本，或者使用绝对路径（例如 . @ConcordionResources("/concordion.css")）。
