Scala Play 2.3.5 - Coveralls sbt 插件 java.io.IOException：无法下载 JavaScript

Question

我目前正在尝试使用 travis、heroku 和 coveralls sbt 插件设置一个 play scala 项目构建链以进行代码覆盖。 我用激活器创建了一个干净的 scala play 应用程序，并添加了工作服插件和一个 travis.yml。

当我推送我的项目并触发构建时，我在 travis 运行测试时收到以下异常：

[error] c.g.h.h.HtmlPage - Error loading JavaScript from [http://localhost:19001/assets/javascripts/hello.js].
java.io.IOException: Unable to download JavaScript from 'http://localhost:19001/assets/javascripts/hello.js' (status 404).

  at com.gargoylesoftware.htmlunit.html.HtmlScript.onAllChildrenAddedToPage(HtmlScript.java:286) [htmlunit-2.13.jar:2.13]

我发现这个旧主题 (https://groups.google.com/forum/#!topic/play-framework/yj4NT3BO0Os) 有相同的错误消息，但不幸的是那里的解决方案都不适合我。

这里有没有人使用工作服或知道我的问题的解决方案？我已经附上了所有的配置文件。

Answer 1

问题出在 sbt-scoverage 上，已在 1.0.0 版中修复。请注意，您必须更新使用插件的方式，因此请参阅自述文件中的设置指南。

Answer 2

错误表明您收到 HTTP 404（未找到）错误：

java.io.IOException: Unable to download JavaScript from 'http://localhost:19001/assets/javascripts/hello.js' (status 404)

所以我认为这不是您的工具的问题，而只是一个简单的老“未找到”问题。 您的项目中有 assets/javascripts/hello.js 文件吗？

Answer 3

这似乎是 sbt-scoverage 插件和播放的问题。希望以后能解决这个问题……
