while runDistributable print path: file:/Users/shinxguangxing/Desktop/ResourceTest/ResourceTest/build/compose/binaries/main/app/ResourceTest.app/Contents/app/ResourceTest-1.0-SNAPSHOT-2ce49fe8d045f05311e2c12a2ba9c4cc.jar!/test

but while runReleaseDistributable

1.buildTypes.release isEnable = false print path: file:/Users/shinxguangxing/Desktop/ResourceTest/ResourceTest/build/compose/binaries/main-release/app/ResourceTest.app/Contents/app/ResourceTest-1.0-SNAPSHOT-2ce49fe8d045f05311e2c12a2ba9c4cc.jar!/test

2.buildTypes.release isEnable =true and add proguard-rules to keep

-keep public class java.lang.Thread {
    public static java.lang.Thread currentThread();
    public java.lang.ClassLoader getContextClassLoader();
}

-keep public class java.lang.ClassLoader {
    public java.URL getResource(java.lang.String);
}


-keep class **.resources.** { *; }

-keepnames class **.resources.** { *; }

print no found

Conclusion:

In release environment, even with proguard-rules added, Thread.currentThread().contextClassLoader.getResource("test") Still unable to retrieve the folder under the resource file

Test Demo: ResourceTest.zip

I hope to get the resource file path in release environment,what should i do?
