It seems like you are encountering the issue of "multiple SLF4J bindings". This problem occurs when there are multiple implementations of the SLF4J logging facade on the classpath.
SLF4J is a logging framework that serves as a simple facade for various logging frameworks such as Logback, Log4j, and java.util.logging. When you have multiple SLF4J bindings on the classpath, it can lead to conflicts and cause issues with logging initialization and output.
To resolve this problem, you need to identify the conflicting SLF4J bindings and exclude the unnecessary ones from your project's dependencies. This can be done by checking your project's dependency tree or using a tool like Maven's dependency plugin.
Once you have identified the conflicting dependencies, you can exclude them by adding exclusion rules in your project's build configuration file (e.g., pom.xml for Maven projects). Here's an example of how to exclude a specific SLF4J binding:
```xml
<dependency>
<groupId>your-dependency-group-id</groupId>
<artifactId>your-dependency-artifact-id</artifactId>
<version>your-dependency-version</version>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
</exclusion>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
</exclusion>
</exclusions>
</dependency>
```
By excluding the unnecessary SLF4J bindings, you can ensure that only one implementation is present in your project's classpath, resolving the "multiple SLF4J bindings" issue.
Remember to adjust the exclusion rules based on your specific project dependencies and the conflicting bindings you identified.
