Execution failed for task ':flutter_inappwebview:compileDebugJavaWithJavac'

When I try to build my Android App I get this error warning:

Execution failed for task ‘:flutter_inappwebview:compileDebugJavaWithJavac’.

Then I run ./gradlew --warning-mode all

My results:

I’m still not sure how to fix this problem so my app will build. Any help would be appreciated

Your output is not really helpful.
Besides that --warning-mode all is good to fix warnings and deprecations, they have nothing to do with a failing build.

Your second line shows that your build is failing when executing the task :flutter_inappwebview:compileDebugJavaWithJavac, but your second command that produces the output just executes the help task and not your failing task.

Just when the build failed, scroll up and check why the task is failing.

If you are using IntelliJ or Android Studio you might easily miss it due to this annoyance: https://youtrack.jetbrains.com/issue/IDEA-226613/Gradle-build-on-failed-build-IDE-auto-focuses-and-shows-incomplete-error-message-which-makes-it-hard-to-understand-why-build so you need to select a higher node in the tree to see the actual error details.
