FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:compileDebugKotlin'.
> Compilation error. See log for more details
* Try:

[!] Your project requires a newer version of the Kotlin Gradle plugin.
Find the latest version on https://kotlinlang.org/docs/gradle.html#plugin-and-versions, then update /Users/wf/Documents/workspace/project/flutter/nolovr-assistant/android/build.gradle:
ext.kotlin_version = ''
Exception: Gradle task assembleDebug failed with exit code 1
根据错误提示，升级Kotlin版本，在android->build.gradle 文件中，修改ext.kotlin_version

改完以后重新运行，以前那个错误没有了，但是又报出一个新的错误：
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:mergeDebugJavaResource'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
> More than one file was found with OS independent path 'META-INF/com.android.tools/proguard/coroutines.pro'

BUILD FAILED in 14s
Exception: Gradle task assembleDebug failed with exit code 1
这时候在android->app->build.gradle 中添加以下内容即可：
packagingOptions {
exclude 'META-INF/com.android.tools/proguard/coroutines.pro'
}

报错二：

Error: ADB exited with exit code 1
Performing Streamed Install
adb: failed to install /Users/wf/Documents/workspace/project/flutter/nolovr-assistant/build/app/outputs/flutter-apk/app.apk: Failure [INSTALL_PARSE_FAILED_MANIFEST_MALFORMED: Failed parse during installPackageLI: /data/app/vmdl1366387552.tmp/base.apk (at Binary XML file line #478): com.sina.weibo.sdk.share.ShareResultActivity: Targeting S+ (version 31 and above) requires that an explicit value for android:exported be defined when intent filters are present]
解决：
将targetSdkVersion改成30 或者更低的版本，重新运行项目

最后项目正常运行。
