title: Using microprofile-config-api: WELD-001408: Unsatisfied dependencies for type String with qualifiers @ConfigProperty
body: <p>I playing with the mpConfig-1.2 feature, but it seems to not work in my setup.</p>
  
  <p>Using Liberty 18.0.0.2.</p>
  
  <p>Have added the maven dependency for microprofile-config-api, CDI is working fine, but the @ConfigProperty is failing at startup with the message</p>
  
  <pre><code>[ERROR   ] CWWKZ0106E: Could not start web application demo-service-ear {1.0-SNAPSHOT}.
  [ERROR   ] CWWKZ0004E: An exception occurred while starting the application demo-service-ear {1.0-SNAPSHOT}. The exception message was: com.ibm.ws.container.service.state.StateChangeException: org.jboss.weld.exceptions.DeploymentException: WELD-001408: Unsatisfied dependencies for type String with qualifiers @ConfigProperty
    at injection point [BackedAnnotatedField] @Inject @ConfigProperty private no.klp.bpm.task.KOPSTask.endpoint2
    at no.klp.bpm.task.KOPSTask.endpoint2(KOPSTask.java:0)
  </code></pre>
  
  <p>The annotation is like this:</p>
  
  <pre><code>@Inject
  @ConfigProperty(name="rule.engine.host", defaultValue="ukjent!")
  private String endpoint2;
  </code></pre>
  
  <p>What can be possible wrong here ?</p>
