Question

我需要你的帮助。请我帮忙。

Error:(63, 0) Cannot set the value of read-only property 'outputFile' for ApkVariantOutputImpl_Decorated{apkData=Main{type=MAIN, fullName=debug, filters=[]}} of type com.android.build.gradle.internal.api.ApkVariantOutputImpl. Open File

applicationVariants.all { variant ->
    variant.outputs.each { output ->
        def file = output.outputFile
        output.outputFile = new File(file.parent, "kickmaterial-" + defaultConfig.versionName + ".apk")
    }
}

安卓版本是3.0.1请您帮忙。

从gradle插件3.0开始，你不能像documentation那样使用each()说:

Using the Variant API to manipulate variant outputs is broken with the new plugin. It still works for simple tasks, such as changing the APK name during build time, as shown below:

// If you use each() to iterate through the variant objects,
// you need to start using all(). That's because each() iterates
// through only the objects that already exist during configuration time—
// but those object don't exist at configuration time with the new model.
// However, all() adapts to the new model by picking up object as they are
// added during execution.

android.applicationVariants.all { variant ->
    variant.outputs.all {
        outputFileName = "${variant.name}-${variant.versionName}.apk"
    }
}

因此，您需要使 block 代码如下所示:

android.applicationVariants.all { variant ->
    variant.outputs.all {
        outputFileName = "$kickmaterial-${variant.versionName}.apk"
    }
}
