java.lang.NoClassDefFoundError software/amazon/awssdk/services/s3/crt/S3CrtSdkHttpExecutionAttribute

[ivanmgb]

Describe the bug

I downloaded the S3 Transfer manager dependency on Maven repo
<dependency> <groupId>software.amazon.awssdk</groupId> <artifactId>s3-transfer-manager</artifactId> <version>2.21.22</version> </dependency>

Setup my configuration and run my app and I got this error.
Running mvn dependency:tree, I noticed that one of the transitive dependency is software.amazon.awssdk:s3:jar:2.20.63

Instead of pulling version 2.21.22 as described under the compille dependencies section: https://mvnrepository.com/artifact/software.amazon.awssdk/s3-transfer-manager/2.21.22

The class S3CrtSdkHttpExecutionAttribute was introduced in https://javadoc.io/static/software.amazon.awssdk/s3/2.21.22/software/amazon/awssdk/services/s3/crt/package-summary.html

and is not in version 2.20.63
https://javadoc.io/static/software.amazon.awssdk/s3/2.20.63/software/amazon/awssdk/services/s3/crt/package-summary.html

Expected Behavior

It should pull the correct version based on the dependencies reported by Maven

Current Behavior

The dependency s3-transfer-manager version 2.21.22 pulled software.amazon.awssdk:s3 version 2.20.63

Reproduction Steps

Added the following in the pom.xml

   <dependency>
        <groupId>software.amazon.awssdk</groupId>
        <artifactId>s3-transfer-manager</artifactId>
        <version>2.21.22</version>
    </dependency>

    <dependency>
        <groupId>software.amazon.awssdk.crt</groupId>
        <artifactId>aws-crt</artifactId>
        <version>0.28.0</version>
    </dependency>

Then run mvn dependency:tree

@ivanmgb can you share your full pom.xml?
My guess is that some other dependency in your pom is pulling in s3 2.20.63

I'll move this to Github Discussion, since it's a guidance question.

Hi @debora-ito Here is the full dependency list of my pom

    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
    </dependency>
    <dependency>
        <groupId>org.apache.commons</groupId>
        <artifactId>commons-text</artifactId>
        <version>1.11.0</version>
    </dependency>
    <dependency>
        <groupId>software.amazon.awssdk</groupId>
        <artifactId>s3-transfer-manager</artifactId>
        <version>2.20.63</version>
    </dependency>
    <dependency>
        <groupId>software.amazon.awssdk.crt</groupId>
        <artifactId>aws-crt</artifactId>
        <version>0.21.12</version>
    </dependency>
</dependencies>

I'll check if there are conflicting dependencies. But currently my workaround is to use an older version of transfer manager and aws-crt. Thank you

To clarify: you have software.amazon.awssdk:s3-transfer-manager declared in two places in the pom file, with versions 2.20.63 and 2.21.22? Because the versions in this pom snippet are different from the pom in the issue description.

Can you share the full pom, not just the dependency list?
