尝试使用 sbt 程序集 [英] trying to use sbt assembly

问题描述

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 - 仍然是这样吗?我有一个 Java 项目，我在项目目录中为其添加了一个 assembly.sbt 文件(根据此版本 sbt 程序集的 sbt 程序集说明):

sbt version is 0.13.9 and scala 2.11.7/ I know previous versions of sbt relied on scala 2.10 - is that still the case? I have a Java project for which I added an assembly.sbt file in the project directory (as per the sbt assembly instructions for this version of sbt assembly):

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

我运行 sbt reload/clean 以及编译.但是，当我尝试运行程序集时，出现以下异常:

I ran sbt reload/clean as well as compile. However, when I try to run assembly, I get the following exception:

> 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]         ^

在我可以使用 sbt 为我的 Java 项目创建一个可运行的 jar 之前，我错过了什么步骤?

what step(s) a I missing before I can create a runnable jar for my java project using sbt?

如果需要，我可以设置合并策略，但是当我尝试使用它时收到了不同的异常.任何有用的建议将非常受欢迎.

I can setup a merge strategy if one is needed but I received a different exception when I tried using that. Any helpful suggestions would be quite welcome.

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，出现以下错误:

I had created the assemly.sbt file in the wrong location. When I placed the assembly.sbt file in the same directory as the build.sbt, and ran reload/compile, I got the following error:

项目结构稍后我会添加屏幕截图.现在，请耐心等待.

Project structure I will add screenshots later. For now, please bear with me.

我尝试在项目子目录中创建 assembly.sbt 文件 - 它不起作用.然后我将它添加到同一个项目子目录中的 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，但并没有解决问题.

I tried creating the assembly.sbt file inside the project subdirectory - it did not work. Then I added it to the plugins.sbt inside the same project subdirectory. When it did not work, I copied the assembly.sbt and plugin.sbt into the root directory of the project but it did not solve the issue.

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

Project directory: test-server I have added assembly.sbt and build.sbt inside /test-server I have also tried adding it ti /test-server/project

都没有用.我有理由确定我做错了什么或在我的配置中遗漏了一些东西.请分享您对解决问题所需要做的事情的想法.

Neither worked. I am reasonably sure I am doing something wrong or missing something in my config. Kindly share your thoughts as to what needs to be done to resolve the issue.

assembly.sbt

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

推荐答案

问题是由于我的 assembly.sbt 文件中的拼写错误造成的.assembly.sbt 文件需要在项目子目录中，即如果您的项目根目录是 test-server，则需要将 assembly.sbt 文件放在 test-server/project 子目录中.

The issue was due to a typo in my assembly.sbt file. The assembly.sbt file needs to be inside the project subdirectory i.e. if your project root directory is test-server, one needs to place the assembly.sbt file inside the test-server/project subdirectory.

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