android - 错误 :Cannot set readonly property: proguardFiles for class: com. android.build.gradle.managed.BuildType

Question

我正在尝试运行来自以下来源的 AR 示例应用程序:https://artoolkit.org/documentation/doku.php?id=4_Android:android_examples

我试图打开项目 ARSimpleProj。但它给了我这个错误:

Error:Cannot set readonly property: proguardFiles for class: com.android.build.gradle.managed.BuildType

我正在使用 Android Studio 2.2.2 和 Gradle 2.14.1

谢谢!

根据 this description ，在版本 0.4.0 中，'+=' 被禁用，而是使用“.add()”代替它。所以声明

proguardFiles += file('proguard-rules.pro')

改为

proguardFiles.add(文件('proguard-rules.pro'))

错误会消失

build.gradle 文件现在看起来像下面这样...注意变化..完成了 2-3 处变化但现在工作得很好。代码如下:-

    apply plugin: 'com.android.model.application' 

    model {
        android {
            compileSdkVersion = 23
            buildToolsVersion = "23.0.2"
        defaultConfig.with {
            applicationId = "org.artoolkit.ar.samples.ARSimple"
            minSdkVersion.apiLevel = 15
            targetSdkVersion.apiLevel = 22
            versionCode = 1
            //Integer type incremented by 1 for every release, major or minor, to Google store
            versionName = "1.0" //Real fully qualified major and minor release description

            buildConfigFields.with {
                //Defines fields in the generated Java BuildConfig class, in this case, for
                create() {           //default config, that can be accessed by Java code
                    type = "int"     //e.g. "if (1 == BuildConfig.VALUE) { /*do something*/}".
                    name = "VALUE"
                    //See: [app or lib]/build/generated/source/buildConfig/[package path]/
                    value = "1"      //     BuildConfig.java
                }
            }
        }
    }

    android.buildTypes {
        release {
            minifyEnabled = false
            proguardFiles.add(file('proguard-rules.pro'))
        }
    }

    android.productFlavors {
    }

    android.sources {
        main{
            jni {
                source {
                    srcDirs = ['src/main/nop']
                }
            }
        }
        main{
            jniLibs {
                source {
                    srcDirs = ['src/main/libs']
                }
            }
        }
    }
}
dependencies {
    compile project(':aRBaseLib')
}
