Java 未能在Jzy3d程序的子模块上执行目标Maven Surefire插件

为了简化我的问题：什么是测试失败，如何纠正它

我是Maven的新手，我正在尝试让图形绘图应用程序在我的计算机上工作。我已经将所有插件更新为父模块和子模块POM文件中的最新版本，并检查Maven是否指向我安装的最新JRE（它就是）

我的依赖树也都很好，它涵盖了我在这个论坛和其他地方看到这个错误的许多途径

我根本无法孤立这个问题

运行mvn包-e时的错误消息如下：

运行il.ac.idc.jdt.SmokeTest配置TestNG时使用：TestNG60Configurator测试运行：1，失败：1，错误：0，跳过：0，运行时间：2.639秒
测试失败是在执行测试时所做断言的负面结果。基本上，您会从被调用的方法或正在读取的字段中得到一个意外的结果

->它坏了，必须修理。这并不意味着你必须修复它

mvn package -Dmaven.test.skip=true

可能有助于建立资源

但是，您可以下载二进制文件，而不是自己构建源代码。这些似乎也可以在网页上找到。
当我在jzy3d的master或0.9.1分支的新克隆上运行
mvn package-e
时，所有测试都通过，maven构建成功

从上面的输出来看，
src/test/java/il/ac/idc/jdt/SmokeTest.java
（在
jzy3d-jdt-core
子模块中）中的
shouldrunonnomperdata
测试失败。查看该测试的源代码，很明显它是为在某种风格的Unix上运行而设计的，因为它引用了硬编码路径
“/inputs/”
和
“/outputs/”

同样从上面的输出来看，很明显，您正在一些flavor窗口上运行，因此测试没有通过也就不足为奇了。如果要通过测试，可以分别将它们更改为
“\\inputs\\\”
和
“\\outputs\\\”
，或者使用更灵活的
文件.separator
，这应该适用于每个操作系统

如果您不关心测试是否通过，只想构建由
mvn package-e
生成的jar文件，那么您可以运行
mvn package-e-DskipTests
。（设置
-Dmaven.test.skip=true也应该起作用；请参阅。）

为了简化我的问题：什么是测试失败，如何纠正它

在Maven项目的构建过程中，它会自动执行所调用的内容。这些是Java类，其目的是验证项目特定方法的行为。在本例中，一个测试在您的构建中失败


2016年3月12日更新：本文中提到的问题已经解决


在Windows上运行时，库的测试确实存在问题。我检查了他们GitHub的主机，我和你有同样的错误

原因是，在单元测试期间，库正在检查两个文件的内容是否相等。但是，一个文件是使用当前操作系统的行分隔符创建的，而控制文件具有Unix行分隔符

如果查看文件
jzy3d jdt core\src\test\resources\outputs\t1\u 1000.tsin\u result.tsin
，您会注意到它使用了Unix
\n
行分隔符。失败的
shouldData
测试正在创建一个临时文件以对照该控制文件进行验证。在我的Windows计算机上，此临时文件是在
C:\Users\{UserName}\AppData\Local\Temp\jdt-4971059362436436156.smf中创建的，如果打开，您可以看到它使用了Windows行分隔符
\r\n
。因此，这两个文件不相等，测试失败

一个可能的解决方案，目标明确
