Question

我和我的团队成员一起开发了一个 Flutter 项目。我最近从 github 中提取并出现了此错误。但是，我的朋友没有同样的问题，也没有从相同的代码中得到错误。

我得到了那个错误

FAILURE: Build failed with an exception.

Where:
Build file 'C:\development\flutter\.pub-cache\hosted\pub.dartlang.org\cloud_firestore-0.16.0\android\build.gradle' line: 41

What went wrong:
A problem occurred evaluating project ':cloud_firestore'.
build_2yq8w8slntfd1pcrdfbqqhulb$_run_closure2$_closure4

或者那个

FAILURE: Build failed with an exception.

* Where:
Build file 'C:\development\flutter\.pub-cache\hosted\pub.dartlang.org\cloud_firestore-0.16.0\android\build.gradle' line: 41

* What went wrong:
A problem occurred evaluating project ':cloud_firestore'.
> Incompatible magic value 0 in class file build_$_run_closure2$_closure4

build.gradle 中的代码行如下

39   android {
40     compileSdkVersion  29
41     compileOptions {
42         sourceCompatibility JavaVersion.VERSION_1_8
43         targetCompatibility JavaVersion.VERSION_1_8
44     }

解决办法是什么？感谢您的帮助。

整个 build.gradle


group 'io.flutter.plugins.firebase.cloudfirestore'
version '1.0-SNAPSHOT'

buildscript {
    repositories {
        google()
        jcenter()
        mavenLocal()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.4'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        mavenLocal()
    }
}

apply plugin: 'com.android.library'

def firebaseCoreProject = findProject(':firebase_core')
if (firebaseCoreProject == null) {
    throw new GradleException('Could not find the firebase_core FlutterFire plugin, have you added it as a dependency in your pubspec?')
} else if (!firebaseCoreProject.properties['FirebaseSDKVersion']) {
    throw new GradleException('A newer version of the firebase_core FlutterFire plugin is required, please update your firebase_core pubspec dependency.')
}

def getRootProjectExtOrCoreProperty(name, firebaseCoreProject) {
    if (!rootProject.ext.has('FlutterFire')) return firebaseCoreProject.properties[name]
    if (!rootProject.ext.get('FlutterFire')[name]) return firebaseCoreProject.properties[name]
    return rootProject.ext.get('FlutterFire').get(name)
}

android {
    compileSdkVersion 29
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    defaultConfig {

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

    lintOptions {

    dependencies {
        api firebaseCoreProject
        implementation platform("com.google.firebase:firebase-bom:${getRootProjectExtOrCoreProperty("FirebaseSDKVersion", firebaseCoreProject)}")
        implementation 'com.google.firebase:firebase-firestore'
        implementation 'androidx.annotation:annotation:1.1.0'

更新

我刚刚删除了以下目录，它可以工作

C:\Users\USER_NAME\.gradle\caches 
C:\Users\USER_NAME\.android\build-cache 
C:\Users\USER_NAME\.android\cache
