java - File inside resource folder is not visible for docker file

Question

I have a spring boot application and I am consuming external soap service and I have requirement to put the wsdl file local and I put it in resources folder under wsdl folder. I am reading that file which is inside resources folder under wsdl folder -

ClassPathResource resource = new ClassPathResource("wsdl/custom.wsdl");
File file = resource.getFile();
wsdlURL = file.toURI().toURL();

I have created a simple Dockerfile with below content and running the spring boot application

FROM openjdk:8-jdk-alpine
ADD target/*.jar /app/app.jar
CMD ["java", "-jar", "/app/app.jar"]
EXPOSE 8080

BUt I am getting below error.

java.io.FileNotFoundException: class path resource [wsdl/custom.wsdl] cannot be resolved to absolute file path because it does not reside in the file system: jar:file:/app/app.jar!/BOOT-INF/classes!/wsdl/custom.wsdl
