Description
java-function-invoker incldudes a shaded dependencies and among those is an older version of jackson. This shaded version of jackson uses the same fully qualified classname as the actual jackson package, which causes it to be picked up by the classloader instead of the actual jackson classes.
This breaks my tests after I added a library that uses jackson's JsonFormat.Feature .READ_UNKNOWN_ENUM_VALUES_USING_DEFAULT_VALUE. When I remove the shaded classes from the test's classpath manually the test works again.
Suggested solution:
This library could just declare a dependency on jackson and instead of shading it into the library jar. If you must use shading you should use the feture of the shading plugin to avoid clashing with the real jackson.
Details:
The clash happens when using the following dependencies:
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-test-google-cloud-functions</artifactId>
<version>3.10.0</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>io.quarkiverse.langchain4j</groupId>
<artifactId>quarkus-langchain4j-vertex-ai-gemini</artifactId>
<version>0.13.1</version>
</dependency>
