我在Windows上并更新到Android Studio(AS)3.0 RC1.当我尝试使用gradle通过AS或终端构建我们的项目时它会停止,Stacktrace就在最后.奇怪的是,在我的同事Mac上它只是建立.

所以我猜这条路有问题.我找不到任何关于此BuildException的具体内容.任何人都知道为什么路径看起来重复？C:\Development\Workspace\Project\app\build\outputs\apk\Test\debug\C:\Development\Workspace\Project\app\build\outputs\apk\Test\debug

我还能尝试解决这个问题吗？我清理,重建并重新启动了我能做的一切.

更新我刚刚更新AS到3.0 RC 2仍然遇到同样的问题.

更新与稳定的AS 3.0版本相同:(

我想在我的项目中使用android构建工具"com.android.tools.build:gradle:3.0.0-alpha4".在我的构建脚本中,我重命名输出apk,它在过去运行良好但似乎不再受支持.

android {

   productFlavors {
        flavorUnsigned {
            applicationVariants.all { variant ->
                variant.outputs.all { output ->
                    output.outputFile = new File(
                            output.outputFile.parent,
                            output.outputFile.name.replace("app-flavorUnsigned-release-unsigned.apk", "DemoApp-${variant.versionName}($variant.versionCode).apk"))
                    def mappingFile = "${rootDir}/app/build/outputs/mapping/${getCurrentFlavor()}/release/mapping.txt"
                    if (variant.getBuildType().isMinifyEnabled()) {
                        variant.assemble.doLast {
                            copy {
                                from "${mappingFile}"
                                into "${rootDir}/app/build/outputs/apk"
                            }
                        }
                    }
                }
            }
        }

    }
}

但是现在我在构建项目时遇到了这个错误

Error:Cannot set the value of read-only property 'outputFile' for ApkVariantOutputImpl_Decorated{apkData=Main{type=MAIN, fullName=flavorUnsignedDebug, filters=[]}} of type com.android.build.gradle.internal.api.ApkVariantOutputImpl.
