Symptoms
When building a Maven project that pulls from the Event Streams schema registry, the build fails with an error similar to the following message:
Could not resolve dependencies for project <project>: Failed to collect dependencies at com.ibm.eventstreams.schemas:<schema-name>:jar:<version>: Failed to read artifact descriptor for com.ibm.eventstreams.schemas:<schema-name>:jar:<version> Could not transfer artifact com.ibm.eventstreams.schemas:<schema-name>:pom:<version> from/to eventstreams-schemas-repository (https://<schema-registry-route>/files/schemas): Not authorized
Causes
The Maven settings.xml code snippets provided in the Event Streams UI for both SCRAM and Mutual TLS are missing the <servers> XML elements.
In addition, the same error can also be displayed when using SCRAM credentials, and the Authorization value does not have the following format: Basic <scram-token>
Resolving the problem
Update the Maven settings.xml file to have the following format:
<settings>
<servers>
<server>
<id>eventstreams-schemas-repository</id>
<configuration>
<httpHeaders>
<property>
<name>Authorization</name>
<value>Basic <scram-token></value>
</property>
</httpHeaders>
</configuration>
</server>
</servers>
<profiles>
<profile>
# ...
Also, if using SCRAM credentials, ensure that the Authorization element has the format Basic <scram-token>, where the <scram-token> value is a Base64-encoded string in the following format: <scram-username>:<scram-password>
