如何在build.sbt中添加依赖项目以运行sbt编译

我是新的sbt建设。 我想将一个依赖项目的java文件（比如Proj a）添加到我的编译项目Proj B中。 在Proj B中运行sbt compile会抛出一个错误，即未找到依赖项目的java包/类。 我浏览了这个链接：但我不清楚如何添加这个依赖项才能使它工作

我尝试在build.sbt中添加一行，但没有成功。 lazy val projB=project.dependsOn/projA

更新

项目的build.sbt： 项目A的build.sbt： 当我在proj B上进行sbt编译时，如果找不到依赖类，它会抛出错误。Hbase类在项目A中

[error] import com.org.config.Hbase;
[error] **\hbase\HbaseDAO.java:38:1:
cannot find symbol
[error]   symbol:   class Hbase
[error]   location: class com.org.hbase.HbaseDAO
[error]         private Hbase hbase;
[error] (Compile / compileIncremental) javac returned non-zero exit code
[error] Total time: 6 s, completed 29/08/2019 9:58:39 AM

建议后更新了build.sbt：

sbt编译时在项目设置projA和projB中的以下库依赖项之后引发错误

libraryDependencies += "org.springframework.boot" % "spring-boot-starter- 
web" % "2.1.6.RELEASE"

在projA设置和

“；”应为，但在projB设置中为此行引发了字符串文字

我对这个错误没有多少线索。

看看你发布的两个代码片段，我猜你有两个独立的build.sbt文件，每个子项目一个。这使得他们独立，一个项目看不到另一个。虽然子项目可能有多个build.sbt文件，但建议在项目根目录中的单个build.sbt文件中定义整个多项目生成

例如，如果您的项目结构如下：

├── project
│  ├── build.properties
│  └── plugins.sbt
├── projA
│  └── src
├── projB
│  └── src
└── build.sbt

然后，您可以将所有生成设置和子项目关系放在根build.sbt中：

然后，如果从项目的根目录启动sbt shell，则可以调用compile或任何其他任务来编译projA和projB，也可以调用projA/compile专门编译该子项目

您已经在阅读文档，因此知道在哪里可以找到更多信息。请注意，您提供的链接指向旧文档，顶部有一条横幅指向新页面：

Hi Siva。你能展示一下build.sbt的相关部分吗？当您添加.dependsOn时，是否会出现错误？它应该是lazy val projB=project.dependsOnprojA没有斜杠，但我认为它只是一个输入错误，谢谢您的回复。更新了问题的更多细节。我也是sbt的新手，我现在的做法可能是完全错误的。谢谢@laugedelic。我仍然有一些问题。在此文本之后使用最新build.sbt内容更新了帖子：在建议之后更新了build.sbt。您需要在内部设置之间添加逗号。设置…谢谢@laughedelic。这有帮助。我的项目正在成功编译。非常感谢你的帮助。
