Flutter BUG！阶段“语义分析”错误中的异常

Question

经过多次搜索并试图解决这个问题，最终我不能，当我试图在真正的手机上运行应用程序时，我得到这个错误：

失败：构建失败，但有例外。

• 出了什么问题：无法打开设置文件“C：\项目\扑腾\埃尔穆斯塔法\android\settings.gradle”的设置通用类缓存（C：\用户\Mahdi MyName.gradle\caches\6.5\scripts\bq3hllkgb26p0nrblf5gh8d37\settings6418c6d726070f323dbddda2aadc82ef）。

错误！源单元“BuildScript”中的阶段“语义分析”中的异常 不受支持的类文件主要版本 60

>

尝试：使用 --堆栈跟踪选项运行以获取堆栈跟踪。使用 --info 或 --调试选项运行以获取更多日志输出。运行 --scan 以获取完整的见解。

构建失败3m43s异常：Gradle任务程序集调试失败，退出代码1

第一次我检查了线下，我注意到我没有:

build.parallel=true

gradle version in \gradle\wrapper\gradle-wrapper.properties 是：

distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-all.zip

我清理了缓存文件夹：

rm -rf $HOME/.gradle/caches/
rm -rf $PROJECT/.gradle/caches/ && rm -rf $PROJECT/build/

我该如何解决这个问题？

Answer 1

由于gradle的缓存覆盖，通常会出现此错误。清理缓存

光盘Android。/gradlew干净

或者您可以手动清理gradle缓存。转到C：\用户\ganesh.gradle\缓存并从那里删除所有缓存。

清理缓存后。你可以升级Gradle。屏幕上显示程序运行的图片

然后运行您的项目。如有必要，只对build.gradle文件截图进行更改

Answer 2

升级导致解决此问题的JDK，我可以构建apk和iphone发布应用程序

Answer 3

我也遇到了同样的问题，但是降级jdk解决了这个问题。

我在计算机中安装了“jdk-16.0.2_windows-x64_bin”，卸载该计算机并安装“jdk-8u301-windows-x64”解决了这个问题。

安装jdk-8u301-windows-x64

请注意，安装“jdk-8u301-windows-x64”时需要在oracle中创建帐户。

完成后，重新启动计算机，然后“运行颤动”，您将很高兴
