Question

我即将参与需要Mechanical Turk java API的Scala / SBT项目。 Mturk提供了如何使用Ant在Java中安装依赖项的说明。我想我可以把准备好的jar（从Maven下载）放到/ lib中，这应该在我的Scala项目中工作，但是在编译时我会遇到依赖性错误。这是因为jar没有与org.apache.commons一起打包吗？

线程“main”中的异常java.lang.NoClassDefFoundError：org / apache / commons / httpclient / protocol / SecureProtocolSocketFactory

更新：

尝试将此依赖项添加到SBT。

libraryDependencies += "net.ettinsmoor" % "java-aws-mturk" % "1.6.2"

您必须将MTurk依赖项添加到您的sbt构建文件（build.sbt）。像那样：

libraryDependencies += "org.clojars.zaxtax" % "java-aws-mturk" % "1.6.2"

在Scala项目中使用带有SBT的jar
