如何在 libGDX 的 Android Studio 上安装 Tween Engine？

Question

我已经下载了两个jar 文件并将它们放在libs 文件夹中。

当我打开 build.gradle 项目 (":core") 时，我找不到应该将此代码放入的依赖项：

compile fileTree(dir: '../libs', include: '*.jar')

它应该看起来像这样，但我在 build.gradle 中找不到它：

project(":core") {
...

dependencies {
    ...
    compile fileTree(dir: '../libs', include: '*.jar')
}
}

这是我在 Gradle 构建日志中得到的错误：

错误：(8, 1) 评估根项目时出现问题 'runningame'。

Could not find method compile() for arguments [directory '../libs'] on org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler_Decorated@72594296.

我的 jar 文件位于：

C:\Users\zfilfah\AndroidStudioProjects\game\core\build\libs

还创建了一个新文件夹用于测试它是否有效：

C:\Users\zfilfah\AndroidStudioProjects\game\core\libs

我错过了什么？我还应该做些什么才能让 Tween Engine 在我的 libGDX Android Studio 上工作？

Android gradle:

android {
    buildToolsVersion "23.0.2"
    compileSdkVersion 23
    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
            jniLibs.srcDirs = ['libs']
        }

        instrumentTest.setRoot('tests')
    }
    defaultConfig {
        applicationId "com.mygdx.game"
        minSdkVersion 8
        targetSdkVersion 23
    }
}


// called every time gradle gets executed, takes the native dependencies of
// the natives configuration, and extracts them to the proper libs/ folders
// so they get packed with the APK.
task copyAndroidNatives() { 
    file("libs/armeabi/").mkdirs();
    file("libs/armeabi-v7a/").mkdirs();
    file("libs/arm64-v8a/").mkdirs();
    file("libs/x86_64/").mkdirs();
    file("libs/x86/").mkdirs();

    configurations.natives.files.each { jar ->
        def outputDir = null
        if(jar.name.endsWith("natives-arm64-v8a.jar")) outputDir = file("libs/arm64-v8a")
        if(jar.name.endsWith("natives-armeabi-v7a.jar")) outputDir = file("libs/armeabi-v7a")        
        if(jar.name.endsWith("natives-armeabi.jar")) outputDir = file("libs/armeabi")
        if(jar.name.endsWith("natives-x86_64.jar")) outputDir = file("libs/x86_64")
        if(jar.name.endsWith("natives-x86.jar")) outputDir = file("libs/x86")
        if(outputDir != null) {
            copy {
                from zipTree(jar)
                into outputDir
                include "*.so"
            }
        }
    }
}

task run(type: Exec) {
    def path
    def localProperties = project.file("../local.properties")
    if (localProperties.exists()) {
        Properties properties = new Properties()
        localProperties.withInputStream { instr ->
            properties.load(instr)
        }
        def sdkDir = properties.getProperty('sdk.dir')
        if (sdkDir) {
            path = sdkDir
        } else {
            path = "$System.env.ANDROID_HOME"
        }
    } else {
        path = "$System.env.ANDROID_HOME"
    }

    def adb = path + "/platform-tools/adb"
    commandLine "$adb", 'shell', 'am', 'start', '-n', 'com.mygdx.game/com.mygdx.game.AndroidLauncher'
}

// sets up the Android Eclipse project, using the old Ant based build.
eclipse {

    // ignores any nodes added in classpath.file.withXml
    sourceSets {
        main {
            java.srcDirs "src", 'gen'
        }
    }

    jdt {
        sourceCompatibility = 1.6
        targetCompatibility = 1.6
    }

    classpath {
        plusConfigurations += [ project.configurations.compile ]        
        containers 'com.android.ide.eclipse.adt.ANDROID_FRAMEWORK', 'com.android.ide.eclipse.adt.LIBRARIES'       
    }

    project {
        name = appName + "-android"
        natures 'com.android.ide.eclipse.adt.AndroidNature'
        buildCommands.clear();
        buildCommand "com.android.ide.eclipse.adt.ResourceManagerBuilder"
        buildCommand "com.android.ide.eclipse.adt.PreCompilerBuilder"
        buildCommand "org.eclipse.jdt.core.javabuilder"
        buildCommand "com.android.ide.eclipse.adt.ApkBuilder"
    }
}

// sets up the Android Idea project, using the old Ant based build.
idea {
    module {
        sourceDirs += file("src");
        scopes = [ COMPILE: [plus:[project.configurations.compile]]]        

        iml {
            withXml {
                def node = it.asNode()
                def builder = NodeBuilder.newInstance();
                builder.current = node;
                builder.component(name: "FacetManager") {
                    facet(type: "android", name: "Android") {
                        configuration {
                            option(name: "UPDATE_PROPERTY_FILES", value:"true")
                        }
                    }
                }
            }
        }
    }
}

核心gradle:

apply plugin: "java"

sourceCompatibility = 1.6
[compileJava, compileTestJava]*.options*.encoding = 'UTF-8'

sourceSets.main.java.srcDirs = [ "src/" ]


eclipse.project {
    name = appName + "-core"


}

Answer 1

解决方法如下：

将两个 jar 放入 libs 文件夹
打开您的项目文件夹并找到 build.gradle 文件 -- 这是根构建
在 "core" 和 "android" 的依赖部分下添加此行 compile fileTree(dir: '../libs', include: '*.jar') 项目。
将这 2 个补间引擎 jar 添加到 IDE 中的模块依赖项。
与 gradle.

Answer 2

进一步为我更改其他答案：

compile fileTree(dir: 'libs', include: '*.jar')

至：

compile fileTree(dir: '../libs/tween-engine-api-6.3.3 2', include: '*.jar')

成功了。（显然你的文件名可能不同（例如末尾没有 2））
