After adding dependencies springwolf-kafka and springwolf-ui app doen't start. Here's the exception:

Welcome to Springwolf. Thanks a lot for reporting your first issue. Please check out our contributors guide and feel free to join us on discord.

Hi @piomin, thanks for reporting this issue.
What version of Spring Boot and Java are you using?

[piomin]

Spring 3.1.3
Java 17

[stavshamir]

It doesn't seem related to Springwolf, please try adding the following dependency and see if the problem is solved:

<dependency>
            <groupId>javax.xml.bind</groupId>
            <artifactId>jaxb-api</artifactId>
            <version>2.3.0</version>
</dependency>

[piomin]

Yes, it solves. But is it the right approach since I already have jakarta.xml-bind-api:4.0.0 included ?

[INFO] +- org.springframework.boot:spring-boot-starter-test:jar:3.1.3:test
[INFO] |  +- org.springframework.boot:spring-boot-test:jar:3.1.3:test
[INFO] |  +- org.springframework.boot:spring-boot-test-autoconfigure:jar:3.1.3:test
[INFO] |  +- com.jayway.jsonpath:json-path:jar:2.8.0:test
[INFO] |  +- jakarta.xml.bind:jakarta.xml.bind-api:jar:4.0.0:runtime
[INFO] |  |  \- jakarta.activation:jakarta.activation-api:jar:2.1.2:runtime

[timonback]

I would have to look at the dependency tree again, but I think swagger-inflector still uses javax.

We plan to remove the dependency in the next release, which should also fix your problem.

I also think the same @piomin, if jakarta.xml-bind-api is on the classpath this error should not be thrown.
I am also facing this error below are the details:

1. Spring Boot: 3.1.5
2. Springwolf Kafka: 0.12.1
3. Java: 17

Hi @deepakdaneva
comments on closed issues are difficult to see. Please create a new issue - feel free to link to this one as a reference.

Have you tried the latest Springwolf version? It contains many improvements, including the fix for the original issue.

[timonback]

Recently, it was discovered that this may happen when swagger-core is used instead of swagger-core-jakarta.
