NoClassDefFound org.eclipse.microprofile.config.ConfigProvider

Question

I have a small rest client project using microprofile 3.3 and i want to deploy it on a raw wildfly 21.0.1.FINAL using the standalone-microprofile.xml.

This project has activated security with jwt and calls another rest-service via @RegisterRestClient-Interface.

I have the problem that the authorization header is not transferred to the following intern rest-call.

In my research i found out that in DefaultClientHeadersFactoryImpl.config() an error occurs that the class ConfigProvider is not found. I thought that using the microprofile-dependency in pom and standalone-microprofile.xml in wildfly add all dependencies for microprofile automatically. Also when i add microprofile-config-api additionally and not provided i get this error.

Does anyone know this problem and how to fix it?

If you need additional information: Just ask ;-)

My only dependency in the pom.xml:

<dependencies>
    <dependency>
        <groupId>org.eclipse.microprofile</groupId>
        <artifactId>microprofile</artifactId>
        <version>3.3</version>
        <type>pom</type>
        <scope>provided</scope>
    </dependency>
</dependencies>

I am launching wildfly with following parameter:

--server-config=standalone-microprofile.xml

The projects are available at Github
