我正在用SBT1.3.8构建的lift 3.3.0上运行Scala2.11.12应用程序。我尝试了4.0.3和4.2.0的。当我使用jetty:start时，我的应用程序会很好地启动，但当我使用jetty:quickstart时，它就无法启动了--我在浏览器中得到了500个错误，当我在控制台中检查应用程序日志时，我看到了java.lang.NoSuchMethodError：'int java.lang.NoSuchMethodError‘，这会导致jetty实例返回一个500。

**编辑我在我的逻辑中更进一步

如何快速开始运行和如何开始运行有什么区别？我想不出这个问题。

下面是我的build.sbt，以防有帮助。在下面，我在jetty:quickstart中包含了请求的控制台日志，显示了我得到的错误。我不明白这个错误的码头:开始。

**编辑2 Ive jun jetty:start然后显示更新，jetty:quickstart然后显示更新。它们都有javax.servlet:servlet:2.5:default作为依赖项。但是jetty:start运行良好并启动容器，而jetty:quickstart无法初始化容器。我不明白为什么一个人成功了，一个人失败了--在我看来，两者都应该失败。

**编辑3我找出了servlet 2.5出现的原因，并更新了paypal依赖项以解决这个问题。我仍然很想知道为什么jetty:start成功了，但是jetty:quickstart没有--它们看起来都应该失败。

jetty:start和jetty:quickstart命令都来自xsbt-web插件。注意，jetty:quickstart与Jetty的Quickstart网络应用程序特性无关。

两者的主要区别在于，start构建了一个完整的项目包，而quickstart没有。使用quickstart，没有创建.war文件，类没有打包到.jar文件中，等等。

使用quickstart，Jetty将使用由sbt管理的项目运行时类路径来运行。使用start，Jetty只运行于您的项目包以及它作为.jar文件包含的依赖项。这可能有所不同，因为sbt的运行时类路径将在provided作用域中包含依赖项，而您的包则不会。这就是为什么一个在为你工作，而另一个却不是。

你的错误：

javax.servlet.http.HttpServletResponse.getStatus()‘：'int javax.servlet.http.HttpServletResponse.getStatus()’‘

指示在类路径上的版本冲突与Jetty所期望的servlet-api .jar之间有一个Jetty。项目的一个或多个依赖项必须对旧版本的servlet-api具有传递依赖关系。

检查依赖树有多种方法。使用Coursier，我看到您的两个Paypal库都依赖于servlet-api 2.5：

代码语言：javascript
复制
├─ com.paypal.sdk:adaptiveaccountssdk:2.4.106
│  └─ com.paypal.sdk:paypal-core:1.4.4
│     ├─ com.google.code.gson:gson:2.2.2 -> 2.8.2 (possible incompatibility)
│     ├─ commons-codec:commons-codec:1.6 -> 1.11 (possible incompatibility)
│     └─ javax.servlet:servlet-api:2.5
├─ com.paypal.sdk:adaptivepaymentssdk:2.6.110
│  └─ com.paypal.sdk:paypal-core:1.4.4
│     ├─ com.google.code.gson:gson:2.2.2 -> 2.8.2 (possible incompatibility)
│     ├─ commons-codec:commons-codec:1.6 -> 1.11 (possible incompatibility)
│     └─ javax.servlet:servlet-api:2.5

这需要排除在外，因为对于您正在使用的Jetty版本来说，它太老了。

在sbt中实现排除传递依赖有多种方法。通过将exclude("javax.servlet", "servlet-api")添加到贝宝依赖项中，我们可以阻止servlet-api的冲突版本。

代码语言：javascript
复制
"com.paypal.sdk" % "adaptivepaymentssdk" % "2.6.110" exclude("javax.servlet", "servlet-api"),
"com.paypal.sdk" % "adaptiveaccountssdk" % "2.4.106" exclude("javax.servlet", "servlet-api"),

您还需要向provided作用域添加一个最近的代码，以便您的代码能够编译：

代码语言：javascript
复制
libraryDependencies += "javax.servlet" % "javax.servlet-api" % "3.0.1" % "provided"
