--------------------------------------

             Summary: Explain validation errors in more depth
                 Key: ARQ-1567
                 URL: https://issues.jboss.org/browse/ARQ-1567
             Project: Arquillian
          Issue Type: Enhancement
      Security Level: Public (Everyone can see)
          Components: Extension - Droidium
    Affects Versions: droidium_1.0.0.Alpha2
            Reporter: Stefan Miklosovic


In many cases, it is not sufficient to provide a user just with stack trace when something goes wrong, for example, from this one:

{code}
java.lang.IllegalStateException: Directory to check against readability is null object or empty string.
  at org.arquillian.droidium.container.configuration.Validate.notNullOrEmpty(Validate.java:98)
  at org.arquillian.droidium.container.configuration.Validate.isReadableDirectory(Validate.java:147)
  at org.arquillian.droidium.container.configuration.AndroidSDK.<init>(AndroidSDK.java:189)
  at org.arquillian.droidium.container.AndroidDeployableContainer.setup(AndroidDeployableContainer.java:153)
{code}

It basically says that user does not have specified JAVA_HOME but he can not know that without looking into sources which is *totally* not desired.

Review all crucial configuration properties and its setters / getters and be sure that when it fails user knows whats going on.
