java.sql.SQLException after upgrading from spring boot 2.6.7 to 2.7.0

We are upgrading our application from spring boot version 2.6.7 to 2.7.0 and we started getting an error on application start up:

java.sql.SQLException: Identity plugin 'AWS-IAM' is used without having AWS SDK in classpath. Please add 'software.amazon.awssdk:rds' to classpath

We already have the below dependency added:

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-rds</artifactId>
    <version>1.12.221</version>
</dependency>

No other changes were made in the code. Any ideas on how to fix this?

Stacktrace:

java.sql.SQLException: Identity plugin 'AWS-IAM' is used without having AWS SDK in classpath. Please add 'software.amazon.awssdk:rds' to classpath

Solution

  • Spring Boot 2.7 has upgraded from 2.7.x to 3.0.x of mariadb-java-client. In 3.0.x, they have made some changes to AwsIamCredentialPlugin. Previously, it looked for the presence of com.amazonaws.auth.BasicAWSCredentials but it now looks for software.amazon.awssdk.auth.credentials.AwsBasicCredentials which is in a different module.

    As the exception message suggests, adding a dependency on software.amazon.awssdk:rds should fix the problem. 2.17.199 is the latest version at the time of writing:

    <dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>rds</artifactId>
    <version>2.17.199</version>
</dependency>
