Hi,

I am using Jackson 2.6.6 version as my aws-java-sdk-core is 1.11.77

i am trying to invoke my aws java code in lambda function. when i run my code i got following errors:

com.fasterxml.jackson.databind.ObjectMapper.enable([Lcom/fasterxml/jackson/core/JsonParser$Feature;)Lcom/fasterxml/jackson/databind/ObjectMapper;: java.lang.NoSuchMethodError

Can anyone help me on this.

Thanks,

Do you know if there are other versions of Jackson potentially available on the classpath? It's possible a different library is pulling in a conflicting version of the library.

If you're not sure, printing the output of this statement may provide some information:

com.fasterxml.jackson.databind.ObjectMapper.class.getProtectionDomain().getCodeSource().getLocation()

I am facing same issue. I am using aws-java-sdk-core-1.11.113 which is internally calling older version of jackson jar. Although I have included the latest version of jackson in my pom.xml and that file is present at classpath too.

The syso of com.fasterxml.jackson.databind.ObjectMapper.class.getProtectionDomain().getCodeSource().getLocation() is 2.4.1. But the dependency which I have included is 2.6.6

The issue in normal wording is "reading a lower jackson version from the aws-java-core folder".

Hi @millems,

Thanks for the reply.

i got file:/var/task/ as output when i put below statement in sysout.
com.fasterxml.jackson.databind.ObjectMapper.class.getProtectionDomain().getCodeSource().getLocation()
my code running inside Amazon Lambda Fucntion. how can i know my invocation Jackson Lib Version.

Please let me know if you need more information.

Thanks,

@anuragmishra1991 ,

when try to invoke below statement in sysout com.fasterxml.jackson.databind.ObjectMapper.class.getProtectionDomain().getCodeSource().getLocation() i got file:/var/task/ as output.
how can i check my jackson library version. My code running inside Amazon lambda fucntion.

Thanks,

[anuragmishra1991]

@janardhan0415
Please try below for checking the version used
System.out.println(com.fasterxml.jackson.databind.ObjectMapper.class.getProtectionDomain().getCodeSource().getLocation())
The syso for me is jar:file:/opt/wildfly/modules/system/layers/base/com/fasterxml/jackson/core/jackson-databind/main/jackson-databind-2.4.1.jar/

For me it is giving specific version of jar from which java class is loaded.

[janardhan0415]

where are you running it from your computer/eclipse/lambda?

[anuragmishra1991]

I am running from Intellij Idea.

[janardhan0415]

i am running it at Amazon Lambda, so it is giving some file path as file:/var/task/ it may be a linux environment.

how can it get the running version inside of file:/var/task/

[anuragmishra1991]

@janardhan0415
I do not know how to get this is Amazon Lambda but you can try digging in this folder to search does this have any folder named fasterxml or jackson-databind.

I hope this will help you to check the version which you are currently referring to.

For the IntelliJ users, the exact fix depends on what you're using to manage your library versions.

1. If you're manually copying jars, you will need to upgrade the jar to at least the 2.6 version required by the AWS DSK.
2. If you're using maven, you can resolve to a higher version manually, as per https://stackoverflow.com/questions/3937195/maven-how-to-override-the-dependency-added-by-a-library
   You should be able to find more information by searching for "override library version" and specifying your dependency management system (eg. gradle, maven).

For Lambda users, you can try the above steps as well as checking the version you're actually deploying to lambda. I'll look to make sure there's nothing else going on with the Lambda case.
