scala 2.10 / sbt 0.13升级时出现奇怪的错误消息

时间：2013-08-29 00:56:14

标签： scala sbt testng

我们正尝试将https://github.com/linkedin/play-testng-plugin升级为scala 2.10 / sbt 0.13，同时使用https://bitbucket.org/jmhofer/sbt-testng-interface/wiki/Home的新版本（3.0.0 vs 2.0.3）

但是，我在sbt编译时遇到一个奇怪的错误，我们无法弄清楚但似乎是由以下代码片段造成的：

class WrappedTestNGRunner(testClassLoader: ClassLoader, loggers: Array[Logger], state: TestRunState) extends TestNGRunner(testClassLoader: ClassLoader, loggers: Array[Logger], state: TestRunState) {
  override def run(testClassname: String, fingerprint: Fingerprint, eventHandler: EventHandler, testOptions: Array[String]) = {
    super.run(testClassname, fingerprint, eventHandler, testOptions)
  }
}

错误消息：

编译错误是由FakeApplication（...）签名的变化引起的。

Uncaught exception during compilation: scala.reflect.internal.Types$TypeError
[error] /home/bliang/Projects/play-testng-plugin/helpers/src/main/java/com/linkedin/plugin/NGTests.java:119: cannot find symbol
[error] symbol  : constructor FakeApplication(java.io.File,java.lang.ClassLoader,java.util.Map<java.lang.String,java.lang.String>,java.util.List<java.lang.String>)
[error] location: class play.test.FakeApplication
[error]         return new FakeApplication(new File(path), Helpers.class.getClassLoader(), getConf(), getPlugins());

您需要更改

return new FakeApplication(new File(path), Helpers.class.getClassLoader(), getConf(), getPlugins());

到

return new FakeApplication(new File(path), Helpers.class.getClassLoader(), getConf(), getPlugins(), null);
NGTest.java中的

：119

由于类路径中不同版本的播放，您可能还会遇到类路径问题。 Play的groupId从“play”改为2.2.x到“com.typesafe.play”，这可能是一个问题，因为sbt会认为play- *的不同版本是不同的工件，因此不会检测冲突的版本。

啊，想出办法解决这个问题。我不得不添加

"org.testng" % "testng" % "6.4", // both 6.4 and 6.8.5 seem to work

到NGPlugin libaryDependencies。回想起来，这只是有意义的，因为sbt-testng-interface中的EventRecorder对org.testng具有编译依赖性。但是，我之前不知道它是如何工作的，因为我们依赖于（2.0.3）的sbt-testng-interface的先前版本也有我依赖的依赖性。
