任务 ':firebase_core:compileDebugJavaWithJavac' 执行失败。 > 找不到 tools.jar

Question

我曾尝试使用 Flutter 进行开发，但是当我使用 android 模拟器时出现此错误。

Execution failed for task ':firebase_core:compileDebugJavaWithJavac'. Could not find tools.jar

我尝试添加

android.useAndroidX=true android.enableJetifier=true

或

org.gradle.java.home=/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

在 gradle.properties 中，但这是同样的问题。

当我指挥颤振医生时，我得到了这个信息。

如何解决？

转到 C:/users//.gradle/cache 删除所有内容然后再次运行。我希望这会有所帮助。
