如何修复应用程序：构建flutter应用程序时的棉绒错误？

Question

出于某种原因，我的应用程序突然无法再构建了。首先我有颤振devtools问题，然后我升级到颤振2.8。1现在我的应用程序无法生成。我试着把Gradle升级到7.3。3和JDK 17，但我的应用程序无法构建，我搜索了整个GitHub和StackOverflow，但找不到解决方案。

这是我的第一个错误：

* What went wrong:
Execution failed for task ':app:processDebugMainManifest'.
←[33m> ←[39mUnable to make field private final java.lang.String java.io.File.path accessible: module java.base does not "opens java.io" to unnamed module @27ec650

我通过添加以下内容来修正：

--add-exports=java.base/sun.nio.ch=ALL-UNNAMED --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.lang.reflect=ALL-UNNAMED --add-opens=java.base/java.io=ALL-UNNAMED --add-exports=jdk.unsupported/sun.misc=ALL-UNNAMED

去gradle.properties.

但是现在当我试图构建时，我得到了另一个错误：

* What went wrong:
Execution failed for task ':app:lint'.
←[33m> ←[39mLint found errors in the project; aborting build.

  Fix the issues identified by lint, or add the following to your build script to proceed with errors:
  ...
  android {
      lintOptions {
          abortOnError false
      }
  }
  ...
  Errors found:

  ...\android\app\src\main\AndroidManifest.xml:5: Error: Class referenced in the manifest, com.example.my_app.${applicationName}, was not found in the project or the libraries [MissingClass]
          android:name="${applicationName}"
                        ~~~~~~~~~~~~~~~~~~
