NoSuchMethodError on JSR310DateTimeDeserializerBase.findFormatOverride -- checked for version incompatibilities

I installed the JSR310 datatype package by adding the below to my build.gradle.

compile group: 'com.fasterxml.jackson.datatype', name: 'jackson-datatype-jsr310', version: '2.9.5'

Once I did so, I started getting the following error on every POST endpoint on my spring-webmvc application:

Handler dispatch failed; nested exception is java.lang.NoSuchMethodError: 'com.fasterxml.jackson.annotation.JsonFormat$Value com.fasterxml.jackson.datatype.jsr310.deser.JSR310DateTimeDeserializerBase.findFormatOverrides(com.fasterxml.jackson.databind.DeserializationContext, com.fasterxml.jackson.databind.BeanProperty, java.lang.Class)'

I followed the advice I found here to remove incompatible extra versions of jackson on my classpath, which I did – I had 2.11.2 installed as well. I removed it, and when this problem persisted, I greped my home folder and removed every trace of that version I could find (from ~/.m2, ~/.gradle/caches, and my tomcat installation). Despite that, I’m still getting the same error. I also tried both downgrading and upgrading from 2.9.5 to 2.8.9 and 2.11.2, cleaning out all traces of other versions of the package each time.

When I run ./gradlew dependencies | grep jackson, all versions of Jackson-related packages are between 2.9.0 and 2.9.5.

Any idea what’s going on here? I’ve been trying to figure this out for more than a day, and I’m not sure what to try next. Thank you.

I found the issue (although I haven’t figured out how to fix it)…there’s a local jar that I’m including that has jackson-databind:2.6.7 in it. When I switched to jackson-databind:2.9.10, per @cowtowncoder’s suggestion, I got a new (but similar) error:

java.lang.NoSuchMethodError: 'void com.fasterxml.jackson.core.JsonGenerator.writeStartObject(java.lang.Object)'

In the process of trying to track that down, I discovered there were two JsonGenerator classes on my classpath, and the older one was inside that local jar.

For anyone else who runs into this issue – you can’t resolve it in the build.gradle or pom.xml files of the project from which you’re requiring the local jar. You have to exclude the old dependency from the build.gradle or pom.xml file of the package that you built the local jar from. Here’s what I mean:

I tried to remove the older version of jackson-databind by adding something like this to my primary build.gradle:

compile (files('path/to/local.jar')) {
	exclude group: 'com.fasterxml.jackson.core', module: 'jackson-databind'
}

That didn’t work. What worked was excluding the old version of jackson-databind from the original pom.xml for the local jar I was using. In my case, that looked like this:

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-signer</artifactId>
    <version>1.11.610</version>

    <exclusions>
	<exclusion>
	    <groupId>com.fasterxml.jackson.core</groupId>
	    <artifactId>jackson-databind</artifactId>
	</exclusion>
    </exclusions>
</dependency>

Then I rebuilt the local jar with mvn package, and referenced that new jar from my build.gradle.

Thank you @cowtowncoder and @kupci for your help!
