如何从 Android Studio 项目中制作 .jar [英] How to make a .jar out from an Android Studio project

问题描述

我正在使用 AndroidStudio，我的项目如下所示:

I'm using AndroidStudio and I have this project as shown:

蓝色圆圈内是 myLib.myLib 还需要使用红色圆圈内的外部库和 apache 包(绿色圆圈).

What is inside the blue circle is myLib. myLib also needs to use an external lib that is inside the red circle, and an apache package (green circle).

所以我想把这整个东西变成一个单独的 .jar，这样我就可以在其他项目中使用它.

So I want to make this whole thing become a single .jar, so I can use it in another projects.

非常感谢您提供分步指南，我是开发者世界的初学者.

A step-by-step guide would be really appreciated, I'm a beginner in the developer world.

谢谢！

推荐答案

• 为库项目打开 build.gradle

  • Open build.gradle for library project

    在build.gradle中写两个任务——deleteJar和createJar并添加规则createJar.dependsOn(deleteJar, build)

    Write two tasks in build.gradle -- deleteJar and createJar and add rule createJar.dependsOn(deleteJar, build)

    上面的代码:

    task deleteJar(type: Delete) {
        delete 'libs/jars/logmanagementlib.jar'
    }           
    
    task createJar(type: Copy) {
        from('build/intermediates/bundles/release/')
        into('libs/jars/')
        include('classes.jar')
        rename('classes.jar', 'logmanagementlib.jar')
    }
    
    createJar.dependsOn(deleteJar, build)
    

    • 从右侧展开 gradle 面板并打开 yourlibrary->others 下的所有任务.您将在那里看到两个新任务——createJar 和 deleteJar

      • Expand gradle panel from right and open all tasks under yourlibrary->others. You will see two new tasks there -- createJar and deleteJar

        双击createJar

        Double click on createJar

        任务成功运行后，从 createJar 任务中提到的路径即 libs/xxxx.jar 中获取生成的 jar

        Once the task run successfully, get your generated jar from path mentioned in createJar task i.e. libs/xxxx.jar

        将新生成的jar复制到你需要的项目的lib文件夹-->右键-->选择添加为库"

        copy the newly generated jar into your required project's lib folder-->right click-->select "add as library"
