试图使用sbt汇编

标签： sbt sbt-assembly

sbt版本是0.13.9和scala 2.11.7 /我知道以前版本的sbt依赖于scala 2.10 - 是不是仍然如此？我有一个Java项目，我在项目目录中添加了一个assembly.sbt文件（根据此版本的sbt程序集的sbt程序集说明）：

addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.2")

我运行了sbt reload / clean以及编译。但是，当我尝试运行程序集时，我得到以下异常：

> assembly
[error] Not a valid command: assembly
[error] Not a valid project ID: assembly
[error] Expected ':' (if selecting a configuration)
[error] Not a valid key: assembly
[error] assembly
[error]         ^

在使用sbt为我的java项目创建可运行的jar之前，我缺少了哪些步骤？

如果需要，我可以设置合并策略，但是当我尝试使用它时，我收到了一个不同的异常。任何有用的建议都会非常受欢迎。

更新

我在错误的位置创建了assemly.sbt文件。当我将assembly.sbt文件放在与build.sbt相同的目录中，并运行reload / compile时，我收到以下错误：

项目结构 我稍后会添加截图。现在，请耐心等待。

我尝试在project子目录中创建assembly.sbt文件 - 它不起作用。然后我将它添加到同一项目子目录中的plugins.sbt。当它不起作用时，我将assembly.sbt和plugin.sbt复制到项目的根目录中，但它没有解决问题。

项目目录：test-server 我在/ test-server中添加了assembly.sbt和build.sbt 我也尝试过添加ti / test-server / project

都没有奏效。我有理由相信我在做错了或在我的配置中遗漏了一些东西。请分享您对解决问题需要采取的措施的看法。

assembly.sbt 

addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.2")

1 个答案:

答案 0 :(得分：1)

问题是由于我的assembly.sbt文件中的拼写错误。 assembly.sbt文件需要位于项目子目录中，即如果项目根目录是test-server，则需要将assembly.sbt文件放在test-server / project子目录中。 

addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.2")
