title: How to fix app:lint error when building flutter app?
body: <p>For some reason, all of a sudden my app cannot build anymore. First I had flutter devtools problem, then I upgraded to Flutter 2.8.1 and now my app cannot build. I tried upgrading Gradle to 7.3.3 and JDK 17 and still, my app cannot build, I searched the whole GitHub and StackOverflow and cannot find a solution.</p>
  <p>This was my first error:</p>
  <pre><code>* What went wrong:
  Execution failed for task ':app:processDebugMainManifest'.
  ←[33m&gt; ←[39mUnable to make field private final java.lang.String java.io.File.path accessible: module java.base does not &quot;opens java.io&quot; to unnamed module @27ec650
  </code></pre>
  <p>Which I fixed by adding:</p>
  <pre><code>--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
  </code></pre>
  <p>to gradle.properties.</p>
  <p>But now when I try to build I get another error:</p>
  <pre><code>* What went wrong:
  Execution failed for task ':app:lint'.
  ←[33m&gt; ←[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.${applicationName}, was not found in the project or the libraries [MissingClass]
            android:name=&quot;${applicationName}&quot;
                          ~~~~~~~~~~~~~~~~~~
