Gradle-一个项目，多个包装，多个罐子 [英] Gradle - one project, multiple packages, multiple jars

问题描述

我在问您一个非常基本的问题，但我希望您能抽出时间来帮助我:

I'm asking you about a very basic question but I hope you can find the time to help me:

我正在尝试实现一个Java项目，该项目可以吐出几个不同的程序，这些程序部分地依赖于我的其他项目.

I'm trying to realise a java-project, that can spit out several different programs which partially have dependencies on other projects of mine.

为了简单起见，我想将所有代码放在一个由Gradle运行的项目中，因此，如果我对中央库(例如数据库连接器)进行更改，则所有子程序都会自动接收更改

In order to keep it simple, I want to have all the code in one project, run by Gradle, so if I make changes to a central library (the database connector for example) all the child-programs automatically recieve the changes.

一个例子可能像这样:

项目:

• program_A
• central_library
• program_B

输出:

• program_A.jar(包括中央库)
• program_B.jar(包括中央库)

现在，在为此找到正确的构建脚本时，我遇到了很大的麻烦，并且想知道这里是否有人可以帮助我.

Now I'm having serious troubles finding a correct buildscript for this and was wondering if someone here could help me out.

P.S.:由于我是新手，所以如果我应该通过Gradleproject中的不同模块而不是Gradleprojects源文件中的不同包来实现这一点，请随时告诉我:)

P.S. : Since I'm new to this, if I should realize this through different modules within the Gradleproject instead of different packages in the Gradleprojects sourcefile, feel free to tell me :)

推荐答案

一种解决方法是拥有一个根项目，其中包含其他三个项目.

One way to approach this is to have a root project, that holds the three other projects inside of it.

在其 settings.gradle 文件中指定子项目:

Specify the sub-projects inside its settings.gradle file:

rootProject.name = 'RootProject'
include 'program_A'
include 'central_library'
include 'program_B'

有了这个， program_a 可以通过在 build.gradle 中添加依赖项来依赖 central_library :

With this in place, program_a can depend on central_library by adding a dependency in its build.gradle:

dependencies {
    compile project(':central_library')
}

我在我的项目之一中进行了类似的设置，尽管中央库"是根项目，而子模块是测试环境.

I have a similar setup in one of my projects, although the "central library" is the root project and the submodules are test environments.
