scala - 在 Delite 中编译我的第一个 DSL

Question

我正在尝试按照使用 Delite+LMS 编译简单 DSL 的教程进行操作。我成功编译了 LMS 和 Delite。现在，密切关注本教程:http://stanford-ppl.github.io/Delite/myfirstdsl.html当我尝试构建我的分析 dsl 时遇到问题。编译器似乎找不到 delite-collection 类:

felix@felix-UX32VD:~/Documents/phd/delite/Delite$ sbt compile

[error]      

                                             ^

有人对我做错了什么有一些见解吗？

来自 SBT 手册:

Library dependencies can be added in two ways:

• unmanaged dependencies are jars dropped into the lib directory

• managed dependencies are configured in the build definition and downloaded automatically from repositories (through Apache Ivy, exactly like Maven)

在任何情况下，在框架项目中添加代码都是一个坏主意，因为您将不得不更改构建过程(例如，添加额外的模块)。此外，您可能必须重新编译框架的所有代码，这会非常慢。
根据框架制作代码的正确方法是:

将库引用为某种存储库中可用的托管依赖项(最佳解决方案)。

将 jar 复制到项目的 lib 文件夹中，并将其添加为非托管依赖项。

由于显然 Delite 在任何 Ivy 存储库中都不可用，因此最好的方法是克隆 Git 存储库并在本地发布它。见 http://www.scala-sbt.org/release/docs/Detailed-Topics/Publishing.html

Publishing Locally

The publishLocal command will publish to the local Ivy repository. By default, this is in ${user.home}/.ivy2/local. Other projects on the same machine can then list the project as a dependency. For example, if the SBT project you are publishing has configuration parameters like:

name := 'My Project'

organization := 'org.me'

version := '0.1-SNAPSHOT'

Then another project can depend on it:

libraryDependencies += "org.me" %% "my-project" % "0.1-SNAPSHOT"
