because of this file, I get following error:

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: You cannot use prior versions of Spring Integration schemas with Spring Integration 4.2. Please upgrade your schema declarations or use versionless aliases (e.g. spring-integration.xsd).
Offending resource: class path resource [com/improvedigital/yield360/services/status/ctx/application-config.xml]

I'm trying really hard to make this work, but I'm out of ideas...help anyone?

Answer 1

Looks like you have a mix of versions in your classpath.

I guess the picture is like:

1. You have spring-integration-core-4.2.x
2. one of your spring-integration-http , ``spring-integration-xml , spring-integration-amqp or spring-integration-core-event is of version 4.1.x`.

When you upgrade to a new version you should do that for all Spring Integration modules at the same time.

The best way to achieve that is to use some Dependency Management tool like Maven or Gradle, when you can specify the version for bounded artifacts as a one variable in one place. During upgrade you'll just change that variable and that's all.
