从Kotlin跨平台项目创建胖子 [英] Create fat jar from kotlin multiplatform project

问题描述

我最近从旧的1.2多平台切换到了1.3.区别在于，每个多平台模块只有一个build.gradle文件(我有5个)，因此配置少得多. 但是我似乎无法配置从jvm平台创建的具有所有依赖项的可运行胖罐. 我曾经在jvm项目和jar任务中使用标准的应用程序"插件，但这不再起作用.我发现有一个"jvmJar"任务，并对其进行了修改(设置Main-class)，但是创建的jar不包含依赖项，并且在ClassNotFoundException上崩溃.我该怎么办?

这就是我现在拥有的:

    jvm() {
        jvmJar {
            manifest {
                attributes 'Main-Class': 'eu.xx.Runner'
            }
            from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
        }

    }

解决方案

我确实碰到了这个障碍，并使用了这项工作.

1.重组您的项目

让我们将您的项目命名为Project.

创建另一个子模块，例如subA，该子模块将具有gradle表示法Project:subA

现在，subA的build.gradle中包含您的多平台代码(这是gradle项目，带有apply:kotlin-multiplafrom)

2.添加另一个子模块

创建另一个仅针对jvm说subB的子模块，该子模块将具有gradle表示法Project:subB

因此，subB将具有插件:'application'和'org.jetbrains.kotlin.jvm'

3.将模块添加为gradle依赖项(请参阅我的build.gradle)

plugins {
    id 'org.jetbrains.kotlin.jvm' version '1.3.31'
    id "application"
}

apply plugin: "kotlinx-serialization"

group 'tz.or.self'
version '0.0.0'

mainClassName = "com.example.MainKt"

sourceCompatibility = 1.8

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

dependencies {
    implementation project(':subA')
}

您可以像常规的Java项目一样继续构建subB，甚至可以使用现有的插件，

I recently switched from old 1.2 multiplatform into 1.3. Difference is, there's one one build.gradle file per multiplatform module (I got 5 of them) so a lot less configuration. However I can't seem to be able to configure creating runnable fat jar with all dependencies from jvm platform. I used to use standard "application" plugin in my jvm project and jar task, but that does not work anymore. I found there's "jvmJar" task and I modified it (set Main-class), but created jar doesn't contain dependencies and crashes on ClassNotFoundException. How do I do it?

This is what I have now:

    jvm() {
        jvmJar {
            manifest {
                attributes 'Main-Class': 'eu.xx.Runner'
            }
            from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
        }

    }

解决方案

I did hit that bump and used this work around.

1. Restructure your project

Lets call your project Project.

create another submodule say subA, which will have the gradle notation Project:subA

now, subA has your multiplatform code in it (It is the gradle project with apply :kotlin-multiplafrom) in its build.gradle

2. Add Another submodule

create another submodule which targets only jvm say subB, which will have the gradle notation Project:subB

So, subB will have plugins: 'application' and 'org.jetbrains.kotlin.jvm'

3. Add your module as a gradle dependency (see my build.gradle)

plugins {
    id 'org.jetbrains.kotlin.jvm' version '1.3.31'
    id "application"
}

apply plugin: "kotlinx-serialization"

group 'tz.or.self'
version '0.0.0'

mainClassName = "com.example.MainKt"

sourceCompatibility = 1.8

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

dependencies {
    implementation project(':subA')
}

you can proceed and build subB as you would a regular java project or even use the existing plugins, it will work
