Question

当我尝试执行“ flutter build apk”时出现以下错误。

警告：处理任务java.io.IO时发生异常：不能写 [C：\ Users \ AndroidStudioProjects \ flutter_project \ build \ app \ intermediates \ transforms \ proguard \ release \ 0.jar] （不会读 [C：\ Users.gradle \ caches \ transforms-1 \ files-1.1 \ media-1.0.0.aar \ 7e094adc751ccc61de6e32709d240e2d \ jars \ classes.jar（;;;;;; **。class）] （重复的jar条目[android / support / v 4 / media / MediaBrowserCompat $ a.class]））线程（任务限制器_1）：破坏

这是mygradle文件：

    def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}

有人可以指出这里有什么问题吗？
