Migrating from Spring 3.2.x to Spring 4 and using ‘spring-mock 2.0.8’ gives “java.lang.NoSuchMethodError: org.springframework.core.CollectionFactory.createLinkedMapIfPossible”

So this is a very short post, with a ‘gotcha’. I wasn’t able to find anything about this, thats why I write it down here right now:

If you are migrating from Spring 3 to 4 and you have in your pom.xml the following dependency:

    <properties>
        <spring.version>3.2.4.RELEASE</spring.version>
        <junit.version>4.9</junit.version>
    </properties>
...
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-mock</artifactId>
            <version>2.0.8</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>${spring.version}</version>
            <scope>test</scope>
        </dependency>

Once you migrate to Spring 4 (lets say 4.0.3.RELEASE) and run your tests you might run into a following stacktrace:

Then all you need to do is make sure that you *DO NOT* have ‘spring-mock’ still in your dependencies configured. As it seems that ‘spring-test’ has assimilated this in its own JAR in Spring 4.

Remove from POM.xml, re-run tests and be happy again. It took me a while to figure this out. I hope it saved you some time!
