java - Error when trying to connect to Azure Eventhub: AzureTokenCredentials / IllegalArgumentException: name

Question

I am following a tutorial on how to setup a connection to Azure EventHub in Spring Boot: [1]

When starting the spring boot app, I get the following error:

2021-01-07 13:37:25.447  WARN 16444 --- [           main] ConfigServletWebServerApplicationContext :

nested exception is java.lang.IllegalArgumentException: name

my.azureauth looks like analogous to the on in [1].

I am using Java 11. Here is the relevant part of my pom:

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>com.microsoft.azure</groupId>
            <artifactId>spring-cloud-azure-eventhubs-stream-binder</artifactId>
            <version>1.2.7</version>
        </dependency>
        <dependency>
            <groupId>com.microsoft.azure</groupId>
            <artifactId>azure-servicebus-jms-spring-boot-starter</artifactId>
            <version>2.3.5</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <!-- Workaround. -->
        <!-- Apparently com.microsoft.azure:spring-cloud-azure-eventhubs-stream-binder:1.2.7 has a transitive -->
        <!-- dependency to the following package. However, it seems that the version is not pinned correctly, so -->
        <!-- we have to pin the version to a compatible one as a workaround. -->
        <!-- 7.5 is apparently the latest version in which com.nimbusds.oauth2.sdk.http.CommonContentTypes is available. -->
        <!-- For a similar (but different) issue see also https://github.com/microsoft/azure-spring-boot/issues/650 -->
        <dependency>
            <groupId>com.nimbusds</groupId>
            <artifactId>oauth2-oidc-sdk</artifactId>
            <version>7.5</version>
        </dependency>

Note the workaround regarding the dependency com.nimbusds.

I tried navigating to the relevant code. However, for some reason the code of AzureContextAutoConfiguration.credentials is not available in the disassembled code of my IDE.

Is the version I used in the workaround in my pom.xml appropriate? Does anyone have an idea what the error means and how to fix it? Can anyone report, that this tutorial still works?

Answer 1

So here the root issue is

"Failed to instantiate [com.microsoft.azure.credentials.AzureTokenCredentials]: Factory method 'credentials' threw exception; nested exception is java.lang.IllegalArgumentException: name"

I would suggest you to verify your my.azureauth and application.properties files again against the guide.

Also, as the guide suggests, if you're using JDK version 9 or greater (you are using 11 here), add the following dependencies

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.1</version>
</dependency>
<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
    <version>2.3.1</version>
    <scope>runtime</scope>
</dependency>
