使用 Play Framework Java 在 Linux/OSX 环境中执行测试时执行异常 InvocationTargetException: null
Execution exception InvocationTargetException: null when executing the tests in Linux/OSX environment using Play Framework Java
我正在使用 Play Framework 2。4.x Java 作为要求的一部分，我需要从外部服务中提取数据。为了解决这个问题，我使用了 WSClient API。我确实按照 Play Framework 文档中提到的步骤测试 Web 服务客户端。 :
https://playframework.com/documentation/2.4.x/JavaTestingWebServiceClients#Returning-files
唯一的区别是我返回 xml 而不是 JSON。当我在 Windows 环境下 运行 时，测试工作正常，但在 Linux 或 Mac 环境下无法执行相同的测试。如果你们中的任何人有一些解决方案，请告诉我。异常详情如下。

看来 "newsfeed.xml" 中的 XML 是错误的。就像你需要一个 "rss" 标签，但它在那个地方是 "html" 标签。
请仔细检查 - 此文件与 windows 上的相同。
我找到了这个问题的解决方案。当我使用“sbt test”命令时，我也能够在 Windows 机器上重现该问题。实际问题是，SendResource() 无法加载 xml 文件。那是因为，xml文件直接放在了test目录下。我将 xml 文件移动到 test/resource 目录，问题得到解决
我正在使用 Play Framework 2。4.x Java 作为要求的一部分，我需要从外部服务中提取数据。为了解决这个问题，我使用了 WSClient API。我确实按照 Play Framework 文档中提到的步骤测试 Web 服务客户端。 : https://playframework.com/documentation/2.4.x/JavaTestingWebServiceClients#Returning-files 唯一的区别是我返回 xml 而不是 JSON。当我在 Windows 环境下 运行 时，测试工作正常，但在 Linux 或 Mac 环境下无法执行相同的测试。如果你们中的任何人有一些解决方案，请告诉我。异常详情如下。

JUnit 测试
public class ScienceFeedTest {

private ScienceFeed scienceFeed;
@Before
public void init() {

ok().sendResource("sciencecloud.xml")

@Test

}
看来 "newsfeed.xml" 中的 XML 是错误的。就像你需要一个 "rss" 标签，但它在那个地方是 "html" 标签。
请仔细检查 - 此文件与 windows 上的相同。
我找到了这个问题的解决方案。当我使用“sbt test”命令时，我也能够在 Windows 机器上重现该问题。实际问题是，SendResource() 无法加载 xml 文件。那是因为，xml文件直接放在了test目录下。我将 xml 文件移动到 test/resource 目录，问题得到解决
