问题描述
通过这条路线开始了一个新项目：
{/* Chart */}
<Grid item xs={12}>
<Paper className={fixedHeightPaper}>
<ChartComponent data={data}/>
</Paper>
</Grid>
如本页所示：https://www.playframework.com/getting-started
它按预期运行。
现在我需要将 AWS 开发工具包的如下部分添加到 sbt new playframework/play-scala-seed.g8
文件中：
build.sbt问题是 "com.amazonaws" % "aws-java-sdk-dynamodb" % "1.12.6"
"com.amazonaws" % "aws-java-sdk-s3" % "1.12.6"
现在堆栈跟踪如下：
sbt run现在我的问题不仅仅是如何解决这个问题？除了在 StackOverflow 上询问之外，这更像是我如何弄清楚如何解决这个问题...
这是谁的问题？ （除了我的现在）
我尝试将 Scala 的版本降低几个档次，因为有时这有帮助，但在这里没有任何乐趣。如果不是真的不需要，我不想倒退主要版本号。
是否有更好的途径来启动一个项目，从而避免其中的一些问题？

我正在编辑这个问题，因为 StackOverflow 询问另一个问题 (Is there a way to stop Scala 2.12 breaking the Jackson object mapper?) 是否有助于解决该问题，然后将其标记为重复。由于上下文很重要，它不是重复的，并且该问题没有回答我的问题，它只是指出了解决方案的可能途径。此外，在这种情况下，对该问题的公认答案实际上是失败的。只是想帮助其他有同样问题的人，不会像我那样浪费时间......
