使用gradle / clojuresq来构建clojure [英] Using gradle/clojuresq to build clojure

问题描述

我想使用gradle / Clojuresque来构建clojure代码，运行它，并得到uberjar。
我使用 http://dev.clojure.org的提示/ display / doc / Getting + Started + with + Gradle ， https：// bitbucket.org/kotarak/clojuresque/wiki/Getting%20Started 和'找不到us.bpsm：edn-java：0.4.3'错误与Gradle的Clojure（Clojuresque）。

I'm trying to use gradle/Clojuresque to build clojure code, run it, and get uberjar. I use hints from http://dev.clojure.org/display/doc/Getting+Started+with+Gradle, https://bitbucket.org/kotarak/clojuresque/wiki/Getting%20Started, and 'Could not find us.bpsm:edn-java:0.4.3' error with Gradle for Clojure (Clojuresque).

这是等级脚本。

buildscript {
    repositories { 
        maven { url "http://clojars.org/repo" } 
        mavenCentral()
    }
    dependencies {
        classpath "clojuresque:clojuresque:1.7.0" 
    }
}

apply plugin: 'clojure'

clojure.aotCompile = true

repositories {
    flatDir dirs: project.file("lib/runtime")
    maven { url "http://clojars.org/repo" }
}

使用 gradle build 任务，没有错误，我有一个jar文件，但我没有看到任何类文件生成;我不认为生成的jar包含任何东西，特别是当我比较手动构建的结果（编译clojure源到类（AOT）从命令行（不使用lein））。

With gradle build task, there is no error and I have a jar file, but I don't see any class file generated; I don't think the generated jar contains nothing, especially when I compared the results from manual build (Compile clojure source into class (AOT) from command line (not using lein)).

.
├── build
│   ├── libs
│   │   └── clojure.jar
│   └── tmp
│       └── jar
│           └── MANIFEST.MF
├── build.gradle
└── src
    └── hello
        └── core.clj

这是core.clj

This is the core.clj

(ns hello.core
  (:gen-class))
(defn -main
  "This should be pretty simple."
  []
  (println "Hello, World!"))

此外，如何运行代码和获得uberjar像 lein run 和 lein uberjar 有吗？

What might be wrong? Also, how to run the code and get uberjar like lein run and lein uberjar does?

推荐答案

创建类文件

源代码应位于 ./ src / main / clojure 它是默认目录。

可以在gradle文件中指定源文件。

One can specify source file in gradle file, though.

sourceSets {
    main {
        clojure {
            srcDirs = ['src']
        }
    }
}

另一个问题是缺少依赖项：

The other issue was with missing dependencies:

repositories {
    maven { url "http://clojars.org/repo" }
    mavenCentral()
}

dependencies {
    compile "org.clojure:clojure:1.6.0"
}

< gradle build 将生成类文件。

我们需要为jar文件设置主类。

We need to set the main class for the jar file.

jar
{
    manifest.attributes("Main-Class": "hello.core")
}

我不确定设置是否非常必要; gradle jar 将生成jar文件。

I'm not exactly sure if the setup is quite necessary; gradle jar will generate the jar file.

这是运行代码的命令：

java -cp .:<PATH>/clojure-1.6.0.jar:build/libs/clojure_test.jar hello.core

uberjar

需要三个修改： href =https://github.com/DevonStrawn/Clojuresque-Boilerplate/blob/master/UberJar/build.gradle =nofollow> https://github.com/DevonStrawn/Clojuresque-Boilerplate/blob/master /UberJar/build.gradle 。

uberjar
{
    manifest.attributes("Main-Class": "hello.core")
}

apply plugin: 'application'

uberjar.enabled = true

执行uberjar

现在只有一个jar执行

Execute the uberjar

Now just one jar for the execution

clojure_test> java -jar build/libs/clojure_test-standalone.jar 
Hello, World!

新的build.gradle文件

The new build.gradle file

buildscript {
    repositories { 
        maven { url "http://clojars.org/repo" } 
        mavenCentral()
    }
    dependencies {
        classpath "clojuresque:clojuresque:1.7.0" 
    }
}

apply plugin: 'clojure'

clojure.aotCompile = true

sourceSets {
    main {
        clojure {
            srcDirs = ['src']
        }
    }
}

repositories {
    maven { url "http://clojars.org/repo" }
    mavenCentral()
}

dependencies {
    compile "org.clojure:clojure:1.7.0"
}

jar
{
    manifest.attributes("Main-Class": "hello.core")
}   

uberjar
{
    manifest.attributes("Main-Class": "hello.core")
}

apply plugin: 'application'

uberjar.enabled = true

阴影jar

从Opal的回答，我添加了创建shadowJar的gradle脚本。它包含设置Main-Class的MAINFEST文件。

Shadow jar

From Opal's answer, I add the gradle script that create shadowJar. It contains the MAINFEST file that sets up the Main-Class.

buildscript {
    repositories { 
        maven { url "http://clojars.org/repo" } 
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath "clojuresque:clojuresque:1.7.0" 
        classpath 'com.github.jengelman.gradle.plugins:shadow:1.2.0'
    }
}

apply plugin: 'application'
apply plugin: 'clojure'
apply plugin: 'com.github.johnrengelman.shadow'

clojure.aotCompile = true
mainClassName = 'hello.core'

sourceSets {
    main {
        clojure {
            srcDirs = ['src']
        }
    }
}

repositories {
    maven { url "http://clojars.org/repo" }
    mavenCentral()
}

dependencies {
    compile "org.clojure:clojure:1.7.0" 
}

或者使用这两行代码而不是清单更改代码： / p>

Or use these two lines of code instead of the manifest change code:

apply plugin: 'application'
mainClassName = 'hello.core'

执行影子jar

获取ubjer jar

Execute the shadow jar

Get the ubjer jar

gradle shadow

作为uberjar。

It's the same as uberjar.

clojure_test> java -jar build/libs/clojure_test-all.jar 
Hello, World!
