Flutter：任务“：geolocator：compileDebugJavaWithJavac”执行失败；

Question

该项目于今年一月前完美建成。但现在它告诉我错误。首先他们向我显示位置 16+ 错误。然后我将位置包更改为地理定位器。但不固定。 然后创建新项目并导入旧代码库。 并将目标和compilesdk更改为31。并取消注释compileOptions

这是我的应用程序级别build.gradle-

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'
}

这是我的pubspec.yaml file -

# The following line prevents the package from being accidentally published to
# pub.dev using `flutter pub publish`. This is preferred for private packages.
publish_to: 'none' # Remove this line if you wish to publish to pub.dev

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43

# Both the version and the builder number may be overridden in flutter

但没有任何效果。 现在仍然显示此错误：

The plugin `geocoder` uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android
V2 embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated
APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding:
https://flutter.dev/go/android-plugin-migration.

我该如何解决此问题。请有人帮我解决这个问题。

Answer 1

@abir-ashan 在我的例子中，此类问题已通过将“geolocator”从 6.2.1 升级到更新版本来解决

% flutter pub outdated
% flutter pub upgrade --major-versions

Answer 2

我遇到了同样的问题并尝试了很多解决方案，但最终通过执行以下更改解决了问题

安卓>应用程序>源代码>构建.gradle

    android {
       compileSdkVersion 31

       defaultConfig {
          minSdkVersion 21
          targetSdkVersion 29
       }
    }
