Question

我正在尝试使用Netbeans设置一个简单的libGDX项目。不幸的是，我的编译器似乎无法找到任何链接到的libGDX jar。是不是Gradle应该自动为您找到并安装所有依赖项？无论如何，当我尝试“运行”桌面项目时，编译器会给我这个：

这是从libGDX项目设置实用程序新生成的代码。我没有做任何改变。我尝试将根项目中的源级别更改为1.6，但这没有帮助。

我读过的另一篇文章建议将libGDX jar放在我的类路径上，但我不确定这些罐子是什么或在哪里找到它们。

我记得大约一年半前做过这件事而没有遇到任何问题。我不确定我做错了什么。

所以我能够通过修补我的build.gradle文件来修复我的问题，该文件的代码取自早期版本的setup插件生成的libGDX项目。基本上，由最新版本的gdx-setup.jar生成的build.gradle具有完全为空的“依赖”子句。我重写了它们看起来像

project(":desktop") {
    apply plugin: "java"


    dependencies {
        compile project(":core")
        compile "com.badlogicgames.gdx:gdx-backend-lwjgl:$gdxVersion"
        compile "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-desktop"

        compile "com.badlogicgames.gdx:gdx-tools:$gdxVersion"
    }
}

project(":android") {
    apply plugin: "android"

    configurations { natives }

    dependencies {
        compile project(":core")
        compile "com.badlogicgames.gdx:gdx-backend-android:$gdxVersion"
        natives "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-armeabi"
        natives "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-armeabi-v7a"

    }
}

        compile "org.robovm:robovm-cocoatouch:$roboVMVersion"
        compile "com.badlogicgames.gdx:gdx-backend-robovm:$gdxVersion"
        compile "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-ios"
        compile "com.badlogicgames.gdx:gdx-bullet-platform:$gdxVersion:natives-ios"
        compile "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-ios"
    }
}

project(":html") {
    apply plugin: "gwt"
    apply plugin: "war"


    dependencies {
        compile project(":core")
        compile "com.badlogicgames.gdx:gdx-backend-gwt:$gdxVersion"
        compile "com.badlogicgames.gdx:gdx:$gdxVersion:sources"
        compile "com.badlogicgames.gdx:gdx-backend-gwt:$gdxVersion:sources"
        compile "com.badlogicgames.gdx:gdx-ai:$aiVersion:sources"
    }
}

project(":core") {
    apply plugin: "java"


    dependencies {
        compile "com.badlogicgames.gdx:gdx:$gdxVersion"
        compile "com.badlogicgames.gdx:gdx-bullet:$gdxVersion"
        compile "com.badlogicgames.gdx:gdx-freetype:$gdxVersion"
        compile "com.badlogicgames.gdx:gdx-ai:$aiVersion"
    }
}

现在桌面项目将编译并运行。尚未尝试过android。 ios项目给了我关于“依赖性解析失败”的错误消息，我不知道如何修复。我有点好奇为什么设置工具没有生成任何依赖信息。

我只是尝试使用最新版本的安装插件再次生成项目，这次工作正常。不确定为什么我的依赖项第一次都是空白的。

Answer 1

我也有同样的问题。

libgdx安装程序在尝试在我的计算机上添加第三方扩展时导致运行时异常。异常发生后，通常显示的常用生成器对话框之一无法显示。

我生成了一个新项目而没有尝试添加任何第三方扩展，我得到了一个成功的项目，我现在可以很好地导入到eclipse中。

无法在Netbeans
