进程无法访问该文件，因为该文件正在被另一个进程使用 [Android] [Gradle]

Question

每当尝试运行 flutter 应用程序时，我都会遇到此错误。

* What went wrong: Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'. java.nio.file.FileSystemException: D:\Projects\buisnesscard\build\app\intermediates\transforms\mergeJavaRes\debug\0.jar: The process cannot access the file because it is being used by another process.

我尝试添加：

packagingOptions { exclude 'META-INF/DEPENDENCIES.txt' exclude 'META-INF/NOTICE' exclude 'META-INF/NOTICE.txt' exclude 'META-INF/LICENSE' exclude 'META-INF/LICENSE.txt' }

到我的构建 gradle 文件并重新启动 android studio 但错误仍然发生。

我的 /app/build.gradle 看起来像这样：

`

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'
}

apply plugin: 'com.android.application'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

android {
    compileSdkVersion 28

    lintOptions {
        disable 'InvalidPackage'
    }

    packagingOptions {
        exclude 'META-INF/DEPENDENCIES.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.seandiacono.buisnesscard"
        minSdkVersion 21
        targetSdkVersion 27
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.google.firebase:firebase-core:17.0.0'
}

apply plugin: 'com.google.gms.google-services'

Answer 1

对我有用的是关闭 Android Studio，转到文件资源管理器中的我的工作区并删除 {project}/app/build。然后重新打开 Android Studio。

Answer 2

试试这个
Android 工作室：

File -> Invalidate Caches / Restart.. > Invalidate/ Restart

或终端：

flutter clean
