提问by BAR
Apparently project dependencies are not being packaged into the jar generated by:
显然，项目依赖项没有被打包到由以下生成的 jar 中：
sbt package
How can dependencies be included?
如何包含依赖项？

There's a project called onejar that will package a project and all its dependencies into a single jar file. There is an SBT plugin as well:
有一个名为 onejar 的项目，它将一个项目及其所有依赖项打包到一个 jar 文件中。还有一个 SBT 插件：
https://github.com/sbt/sbt-onejar
https://github.com/sbt/sbt-onejar
However if you're just looking to create a standard package (deb, rpm, etc.) there is sbt-native-packager:
但是，如果您只是想创建标准包（deb、rpm 等），则可以使用 sbt-native-packager：
https://github.com/sbt/sbt-native-packager
https://github.com/sbt/sbt-native-packager
It can place all your dependencies into a Linux package and add the appropriate wrappers to load all your dependencies and start your program or service.
它可以将您的所有依赖项放入一个 Linux 包中，并添加适当的包装器来加载您的所有依赖项并启动您的程序或服务。

Well, I use sbt-assemblypluginto create jar with dependencies,
好吧，我使用sbt-assembly插件来创建具有依赖项的 jar，
(1) add sbt-assemblyto projects/assembly.sbt
(1) 添加sbt-assembly到projects/assembly.sbt
echo 'addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.8")' > project/assembly.sbt
(2)run sbt clean assemblyto build the jar.
It will create ${name}-assembly-${version}.jarin target/scala-${scalaVersion}
(2)运行sbt clean assembly以构建 jar。它会${name}-assembly-${version}.jar在target/scala-${scalaVersion}
(3) Only in case you get infamous de-duplicate error, use assemblyMergeStrategyas described in here
(3) 仅当您遇到臭名昭著的重复数据删除错误时，请assemblyMergeStrategy按照此处的说明使用
