Leiningen 基础用法
Leiningen 是一个用途广泛的工具, 是clojure工具链的纽带.
- 管理库依赖
- 编译、打包
- 工程模版
- 插件集成
创建新工程
lein new [app | default | plugin | template ] name
- app – 创建一个带
-main函数的模版工程 - default – 创建一个库项目, 可以被其它的项目依赖
- plugin – 创建一个插件
- template – 创建一个模版, 类似Marvin创建的红创模版，这部分待他补充吧.
执行项目
lein run
启动repl
lein repl
打包一个库
lein jar 或者lein install
这样打的包不包含外部依赖的jar, 不可以单独执行.
编译, 打包, 在target目录下生成一个jar
$ lein jar
Created /Users/user/source/me/my-library/target/my-library-0.1.0-SNAPSHOT.jar
编译, 打包，生成pom.xml文件和jar, 并且copy这两个文件到本地的~/.m2目录下.
$ lein install
Created /Users/user/source/me/my-library/target/my-library-0.1.0-SNAPSHOT.jar
Wrote /Users/user/source/me/my-library/pom.xml
Installed jar and pom into local repo.
打包一个应用程序
lein uberjar 给我们打包应用程序的能力，它会把依赖的库，资源文件一起打包. 成功打包以后可以直接执行.
$ lein uberjar
Compiling my-project.core
Created /Users/user/source/me/my-project/target/uberjar/my-project-0.1.0-SNAPSHOT.jar
Created /Users/user/source/me/my-project/target/uberjar/my-project-0.1.0-SNAPSHOT-standalone.jar
查找依赖
lein search 可以用来查照Maven的库里有的包
$lein search excel

测试
比如我们工程中的:
lein test: 执行一次test
lein test-refresh: test runner 始终运行test
lein cloverage: 查看测试覆盖率
编译
把clj文件和java文件编译为class.
lein compile
在我们的项目中执行这个命令什么都不会发生, 因为我们
- 没有指定
:aot(ahead of time)的编译 - 没有指定
:java-source-paths, 也就是没有Java文件
我们稍后会有一篇文章专门讲Java和Clojure的编译和interop的问题.
