Error occurs java.lang.NoSuchMethodError: reactor.core.publisher.MonoSink.contextView() after updating Quarkus version

Question

I have updated the quarkus version of the project from 2.13.final to 2.16.4 final. Then it gives an error as follows. java.lang.NoSuchMethodError: reactor.core.publisher.MonoSink.contextView()

The dependency tree of reactor.core is as follows.

+- com.azure:azure-storage-blob:jar:12.12.0:compile
[INFO] |  +- com.azure:azure-core:jar:1.37.0:compile
[INFO] |  |  +- com.fasterxml.jackson.core:jackson-annotations:jar:2.14.2:compile
[INFO] |  |  +- com.fasterxml.jackson.core:jackson-core:jar:2.14.2:compile
[INFO] |  |  +- com.fasterxml.jackson.core:jackson-databind:jar:2.14.2:compile
[INFO] |  |  +- com.fasterxml.jackson.datatype:jackson-datatype-jsr310:jar:2.14.2:compile
[INFO] |  |  \- io.projectreactor:reactor-core:jar:3.4.7:compile

As mentioned in java.lang.NoSuchMethodError: 'reactor.util.context.ContextView reactor.core.publisher.MonoSink.contextView()' I tried changing the version of reactor-core. But it didn't fix the issue.

@Banula Kumarage Welcome to Microsoft Q&A Forum, Thank you for posting your query here

This error typically occurs when there is a version mismatch between the reactor-core library used by your project and the version of reactor-core expected by one of its dependencies. In this case, it looks like the azure-storage-blob library is bringing in an older version of reactor-core (3.4.7) that is not compatible with the version of reactor-core your project is using (presumably 3.4.9 or higher).

To resolve this issue, you can try explicitly excluding the transitive dependency on reactor-core from the azure-storage-blob library in your pom.xml file or build.gradle file, and then adding a direct dependency on the version of reactor-core that your project is using. Here's an example of how to do this in a Maven project:

pom.xml

 

<dependency>
  <groupId>com.azure</groupId>
  <artifactId>azure-storage-blob</artifactId>
  <version>12.12.0</version>
  <exclusions>
    <exclusion>
      <groupId>io.projectreactor</groupId>
      <artifactId>reactor-core</artifactId>
    </exclusion>
  </exclusions>
</dependency>

Then, you can add a direct dependency on the version of reactor-core that your project is using:

<dependency>
  <groupId>io.projectreactor</groupId>
  <artifactId>reactor-core</artifactId>
  <version>3.4.9</version>
</dependency>

This should ensure that your project is using the correct version of reactor-core and that there are no conflicts with other dependencies that require a different version.

   

If you have any additional questions or need further clarification, please let me know.

Getting the same error after upgrading Spring Boot 3.1.4 and after downgrading reactor core to 3.4.19 version, it works.

<dependency>
  <groupId>io.projectreactor</groupId>
  <artifactId>reactor-core</artifactId>
  <version>3.4.9</version>
</dependency>
