java - 找不到参数的方法实现()[org.jetbrains.kotlin :kotlin-stdlib-jdk7:1. 3.50]

Question

我也是 Android 开发和 Flutter 的新手。导出我的应用程序时，我遇到很多错误，目前卡在这个错误上。不知道如何解决这个问题。如果你们能帮助我，那将是很大的帮助!

收到此错误:

FAILURE: Build failed with an exception.

* Where:
Build file 'F:\GAMES\quiz\android\app\build.gradle' line: 88

* What went wrong:
A problem occurred evaluating project ':app'.
> Could not find method implementation() for arguments [org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.3.50] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDepen
dencyHandler.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

Running Gradle task 'assembleRelease'... Done                       4.3s
Gradle task assembleRelease failed with exit code 1

我认为 gradle 文件中一定存在一些错误，因此包括下面的 gradle 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 FileNotFoundException("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'
}

您在其中添加实现“org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version”的依赖项 block 位于buildscript内 block 。 这意味着您正在尝试修改构建使用的依赖项，而不是项目使用的依赖项。

• 构建依赖项仅使用 classpath 配置，因此如果这是您的目标，请将实现替换为classpath。
• 项目依赖项必须在与 android block 处于同一级别的 dependencies block 中声明。请参阅Android documentation了解详情。因此，如果这是您的目标，请将该行移动到新的依赖项 block
