extra dependency needed: org.apache.httpcomponents.client5 httpclient5

[serban-cordis]

Hi,

I am using a simple CLI project, no other dependencies besides:

        <dependency>
            <groupId>com.windowsazure</groupId>
            <artifactId>Notification-Hubs-java-sdk</artifactId>
            <version>1.0.3</version>
        </dependency>

    public static void main(String[] args) throws NotificationHubsException {
        NotificationHubClient client = new NotificationHub(HUB_CONNECTION_STRING, HUB_NAME);
    }

I am getting a class definition not found: Exception in thread "httpclient-dispatch-1" java.lang.NoClassDefFoundError: org/apache/hc/core5/http2/impl/nio/ClientHttpProtocolNegotiator at org.apache.hc.client5.http.impl.async.HttpAsyncClientEventHandlerFactory.createHandler(HttpAsyncClientEventHandlerFactory.java:257)

When i checked, org.apache.hc.core5.http2.impl.nio.ClientHttpProtocolNegotiator cannot be found in org.apache.httpcomponents.client5:httpclient5:5.1.3 jar

To fix this i have to add and extra:

        <dependency>
            <groupId>org.apache.httpcomponents.client5</groupId>
            <artifactId>httpclient5</artifactId>
            <version>5.2-beta1</version>
        </dependency>

This dependency contains the missing class.

Why is this not included directly in the notification-hubs-java-sdk artifact? I am using 1.0.3, the latest version on maven repo.

Should a new release with the upgraded http be required in order for this to work directly without any extra artifacts?

Please advise.

Thank you, Serban

The latest stable version of org.apache.httpcomponents (5.2, 5.2.1) doesn't contain the class org.apache.hc.core5.http2.impl.nio.ClientHttpProtocolNegotiator.

So with Notification-Hubs-java-sdk 1.0.3, you should stay on version 5.2-alpha2 of org.apache.httpcomponents. You can use httpcore5 or httpclient5:

<dependency>
          <groupId>org.apache.httpcomponents.core5</groupId>
          <artifactId>httpcore5</artifactId>
         <version>5.2-alpha2</version>
</dependency>

<dependency>
            <groupId>org.apache.httpcomponents.client5</groupId>
            <artifactId>httpclient5</artifactId>
            <version>5.2-alpha2</version>
</dependency>
