jvm target incompatibility

[SpirikleOfficial]

Getting this error:

Execution failed for task ':update_available_android:compileDebugKotlin'.

'compileDebugJavaWithJavac' task (current target is 1.8) and 'compileDebugKotlin' task (current target is 17) jvm target compatibility should be set to the same Java version.

if we have in android/settings.gradle the following config then it works:

    id "dev.flutter.flutter-plugin-loader" version "1.0.0"
    id "com.android.application" version "7.3.0" apply false
    id "org.jetbrains.kotlin.android" version "1.7.10" apply false
}

but if the above are changed to:

    id "dev.flutter.flutter-plugin-loader" version "1.0.0"
    id "com.android.application" version "8.0.2" apply false
    id "org.jetbrains.kotlin.android" version "1.9.0" apply false
}

then the error is recieved.

update_available version: 3.1.0+1

[mateusfccp]

Thank you for your report.

Can you provide a minimal reproduction sample?

[SpirikleOfficial]

Open the default flutter project and add the lines mentioned previously. Also in the gradle-wrapper.properties file change the distributionURL to:

distributionUrl=https\://services.gradle.org/distributions/gradle-8.3-bin.zip

The above changes gave us the error.

What version of Flutter are you using? Did it used to work in previous versions?

[SpirikleOfficial]

Yes it did used to work previously. It seems the flutter version is not the culprit but the gradle versions are. As we tried to run on latest flutter default project and there it ran perfectly but with old gradle versions.

any update on how long this is going to take? We need to use it before 29 Aug.

Hello, @SpirikleOfficial.

Could you open a PR with a fix?

I'm not sure I'll be able to do it myself before tomorrow, as I'm a little busy this week, but I could definitely review your PR.

[mateusfccp]

@SpirikleOfficial Can you test against master? I just committed a potential solution.

In my personal tests, it should now emit a warning but compile nonetheless.

[SpirikleOfficial]

Will check and let you know

[mateusfccp]

@SpirikleOfficial I don't want to bother you, but could you test it?

I want to release a new version after this has been solved.

[SpirikleOfficial]

Used this in our pubspec.yaml:

dependency_overrides:
  update_available:
    git:
      url: https://github.com/mateusfccp/update_available
      ref: master
      path: update_available
  update_available_ios:
    git:
      url: https://github.com/mateusfccp/update_available
      ref: master
      path: update_available_ios
  update_available_android:
    git:
      url: https://github.com/mateusfccp/update_available
      ref: master
      path: update_available_android

Compiled with success. However, our debug app had old version and Google play store shows update available but we are getting UnknownAvailability() everytime. The same code worked previously when your package was able to compile but not now. The code is:

 final updateAvailability = await getUpdateAvailability();
    switch (updateAvailability) {
      case UpdateAvailable():
        {
          print('update available');
        }
      case NoUpdateAvailable():
        {

          print('no update available');
        }
      case UnknownAvailability():
        {
          print('unknown update available');
        }
    }

Are we doing something wrong in our code or there is a problem in the package?

[mateusfccp]

@SpirikleOfficial

That's interesting (and weird).

Does anything appear in the Java logs?

[SpirikleOfficial]

These are the logs after the getUpdateAvailablity() is called:

[mateusfccp]

UnknownAvailability means specifically that something happened that prevented the plugin from discovering the availability, probably an error.

It's weird that it didn't happen before and is happening now.

The log doesn't show anything relevant.

[mateusfccp]

@SpirikleOfficial

Please, update your code to the latest master.

I exposed the PlatformException from the method channel to the UnknownAvailability object.

Please, test your code again and check whether the error and stackTrace object are non-null. They may give us more insight about what's happening.

Your packages are wrong for some reason.

update_available_platform_interface should be 4.1.0-dev.1 instead of 4.0.1.

Are you sure you removed all overrides?

[SpirikleOfficial]

Please tell the code to write in pubspec.yaml

[mateusfccp]

dependencies:
  update_available: 3.2.0-dev.1

You shouldn't have anything related to update_available in dependency_overrides.

[SpirikleOfficial]

[mateusfccp]

Can you see if any error is returned in the UnknownAvailability object?

Notice that now it has two fields, error and stackTrace. They should have a PlatformException and it's exception.

[SpirikleOfficial]

used this code:

 case UnknownAvailability():
        {
          print(
              'error from updateAvailability object: ${updateAvailability.error}');
          print(
              'stackTrace from updateAvailability object: ${updateAvailability.stackTrace}');
        }
