在Windows 10(Intellij IDEA)上安装带有gradle项目的Google或工具 [英] Installing Google or-tools with gradle project on Windows 10 (Intellij IDEA)

问题描述

是否可以在IntelliJ Idea上安装库?

Is it possible to install the library on IntelliJ Idea?

还是我必须使用Visual Studio 2017?

or do I have to use Visual Studio 2017?

如果是，该如何安装?我发现Google文档令人困惑.

If so, how do I install it? I find the google documentation confusing.

推荐答案

万一其他人来了，这是我使用Gradle构建和运行OR工具的配置.

In case anyone else comes here, this is my configuration for building and running OR-tools with Gradle.

首先，我有一个顶层项目，其中有与应用程序相关的代码，称为suite，还有一个模块，其中我分离了所有与OR-Tools相关的代码，称为optimization.在optimization模块中，我有一个文件夹lib，其中包含以下文件(不确定是否需要所有文件):

First of all, I have a top-level project where I have application-related code, called suite, and a module where I have separated all the OR-Tools related code, called optimization. In the optimization module, I have a folder lib which contains the following files (not sure if you need all of them):

com.google.ortools.jar
libcvrptw_lib.so
libdimacs.so
libjniortools.so
libortools.so

如您所见，这里没有protobuf.jar-稍后再介绍.然后，将以下内容添加到现有的顶级build.gradle文件中:

As you can see, there's no protobuf.jar here -this comes later. Then I added the following to my existing top-level build.gradle file:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.google.protobuf:protobuf-gradle-plugin:0.8.6'
    }
    ...
}

apply plugin: 'application'

applicationDefaultJvmArgs = ["-Djava.library.path=optimization/lib"]

mainClassName = 'com.package.name.MainClass'

请注意，对于applicationDefaultJvmArgs，您必须将路径更改为lib文件夹.当然，将mainClassName更新为您的主类.

Note that for applicationDefaultJvmArgs you have to change the path to your lib folder. And of course, update mainClassName to your main class.

最后，在我的optimization模块的build.gradle中，添加了以下依赖项:

And finally, in the build.gradle of my optimization module I added the following dependencies:

dependencies {
    compile files('lib/com.google.ortools.jar')
    compile 'com.google.protobuf:protobuf-java:3.0.0'
    ...
}

以上代码从lib文件夹编译ortools.jar，并从mavenCentral下载protobuf-java库.

The above compiles ortools.jar from the lib folder and downloads the protobuf-java library from mavenCentral.

PS.不要忘记在访问OR工具的Java类中加载jniortools库:

PS. Don't forget to load the jniortools library in your Java class that accesses OR-tools:

static {
    System.loadLibrary("jniortools");
}

很显然，您不需要子模块即可完成此工作-这只是我的实现.希望这会有所帮助.

Obviously, you don't need sub-modules to make this work - this is just my implementation. Hope this helps.
