Play2：播放阶段命令失败，并显示“未找到：类型 SetupContext”

Question

我目前正在尝试将 Play 2.2.2 应用程序部署到 heroku，play stage 命令对我来说失败，输出如下：

这是我的 build.sbt：

name := "test"

version := "1.0-SNAPSHOT"

libraryDependencies ++= Seq(
    javaJdbc,
    cache,
    "be.objectify" %%                       "deadbolt-java" %               "2.2.1-RC2",
    "com.google.guava" %                    "guava" %                       "r09",
    "com.codahale.metrics" %                "metrics-core" %                "3.0.1",

    "com.restfb" %                          "restfb" %                      "1.6.11"
)

resolvers += Resolver.url("Objectify Play Repository", url("http://schaloner.github.com/releases/"))(Resolver.ivyStylePatterns)

resolvers += "Sedis Repo" at "http://pk11-scratch.googlecode.com/svn/trunk"

play.Project.playJavaSettings

这是有问题的文件：

package com.bvg.controllers.json.serializers;

import java.util.Map;

import com.fasterxml.jackson.databind.module.SimpleModule;

public class TestJacksonModule extends SimpleModule {
    private static final long serialVersionUID = 1L;

    protected Map<Class<?>, Class<?>> mixIns;

    public FeudJacksonModule() {
        super("FeudJacksonModule");
    }

    @Override
    public void setupModule(SetupContext context) {
        super.setupModule(context);

        for (Map.Entry<Class<?>, Class<?>> mixIn : mixIns.entrySet()) {
            context.setMixInAnnotations(mixIn.getKey(), mixIn.getValue());
        }
    }

    public void setMixIns(Map<Class<?>, Class<?>> mixIns) {
        this.mixIns = mixIns;
    }
}

我也尝试添加 jackson-databind 依赖，但似乎没有帮助："com.fasterxml.jackson.core" % "jackson-databind" % "2.2.2"

我已经搜索了所有内容，但似乎无法找到导致此问题的原因。这里有一个相关的讨论：

https://groups.google.com/forum/#!topic/play-framework/aa90AAp5bpo

它提到禁用 scaladoc 生成。不确定这是否是原因或如何使用 build.sbt 而不是 Build.scala 来解决这个问题，正如讨论所建议的那样。任何见解都值得赞赏。

Answer 1

看来您需要做的就是将以下行添加到 build.sbt 的末尾：

sources in doc in Compile := List() 

希望这可以避免其他人头疼..
