Javafx application

javafx · February 24, 2022, 2:43pm

hi,I use proguard to obfuscate a javafx application ,I have config -adaptresourcefilecontents **.fxml ,but it does not work ,the name of the controller class had changed ,but in fxml,the corresponding class name dose not change ,for example ,in fxml file ,there is a config fx:controller=“queshens.controller.CameraSettingStageController” ,queshens.controller.CameraSettingStageController is the full name of the class ,which has been obfuscated as A.C.
how to do with this situation,the similar question is javafx - Proguard does not process onAction calls in FXML - Stack Overflow
thans for watching.

Hi @javafx ,

Can you share the full configuration with us? Is it just for this specific controller or are none of the classes in the fxml files renamed? Which ProGuard version are you using at the moment?

I quickly tried replicating the issue in a small Javafx sample but it seems to work correctly on my end.

Best regards,

Jonas

now, I download the source ,and debug,print some logs show that in the action of Shrinker ,the class had disappear .

jonas.gijbels · March 7, 2022, 10:34am

Hi @javafx ,

ProGuard indeed removes classes that are not really used in the code. This needs configuration as it can happen that a class that is actually used, is still removed by ProGuard. Adding a -keep rule for that class should do the trick;

-keep class com.example.MyClass

Please consult the troubleshooting guidelines for more info.

Best regards,

Jonas

javafx · March 9, 2022, 6:59pm

thanks,and now I have a new question,
i have config

-keepclassmembers class * {
    @javafx.fxml.FXML
    <fields>;
    @javafx.fxml.FXML
    <methods>;
}

and after obfuscates,the fields annotation with @FXML don’t rename ,but the methods name which annotion with @FXML have change,It should not be rename.

and the action compoent corresponding this methods name have not change ,even if I have config -adaptresourcefilecontents **.fxml , does -adaptresourcefilecontents cofig just modify the class name ,not modify the mothod name?

thanks for watching,waitting your reply

james · March 11, 2022, 5:16pm

Hi @javafx ,

I can see from your keep rules that the processLogin method should not be renamed.

If you write the method name explicitly in your keep rules does it work? e.g.

-keepclassmembers class * { public void processLogin(...); }

Are you able to provide a sample that reproduces the problem?

does -adaptresourcefilecontents cofig just modify the class name ,not modify the mothod name?

Yes, -adaptresourcefilecontents only modifies the class names in resource files not method names

Thanks,

James
