> Call to <ivy:settings> results in different errors if override is not 
> explicitly set to 'true'.   The failure behavior depends whether override is 
> set to false or not set at all.
> These tests both call the target "resolve-dependencies" which depends on a 
> target  "bootstrap-ivy".  The <ivy:settings> only gets called from 
> "bootstrap-ivy".
> If override is not set at all, this is the error:
> C:\allworkspaces\ivy-poc\hellorm\hello-A\src\build-wrapper.xml:47: overriding 
> a previous definition of ivy:settings with the id 'module-settings' is not 
> allowed when using override='notallowed'.
>       at org.apache.ivy.ant.IvyAntSettings.execute(IvyAntSettings.java:262)
> If override is set to 'false', I get this error:
> C:\allworkspaces\ivy-poc\hellorm\hello-A\src\build-wrapper.xml:47: 
> java.lang.NullPointerException
>       at org.apache.tools.ant.Task.perform(Task.java:357)
>       at 
> org.apache.ivy.ant.IvyAntSettings.getConfiguredIvyInstance(IvyAntSettings.java:249).
>    
> This test calls the target "bootstrap-ivy" directly.   The behavior is same 
> as above if I don't set override.   However, if I set override to false, I 
> don't get the NPE anymore, I get a warning about the settings already being 
> defined:
> [ivy:settings] a settings definition is already available for 
> module-settings: skipping
