    Description

      If you run Ivy on this ivy.xml:

      <?xml version="1.0" encoding="UTF-8"?>
      <ivy-module version="1.0">
      <info organisation="myself" module="ivytest"/>
      <dependencies>
      <dependency org="apache" name="dom4j" rev="1.6"/>
      </dependencies>
      </ivy-module>

      All is fine. But I am American and I accidentally wrote

      <?xml version="1.0" encoding="UTF-8"?>
      <ivy-module version="1.0">
      <info organization="myself" module="ivytest"/>
      <dependencies>
      <dependency org="apache" name="dom4j" rev="1.6"/>
      </dependencies>
      </ivy-module>

      (Note s/isa/iza/.) Ivy handles this as follows under normal logging level:

      exception while parsing: null in file:/tmp/ivytest/ivy.xml

      BUILD FAILED
      /tmp/ivytest/build.xml:22: syntax errors in ivy file

      Hmm. Using ant -v:

      using ivy parser to parse file:/tmp/ivytest/ivy.xml
      exception while parsing: null in file:/tmp/ivytest/ivy.xml

      BUILD FAILED
      /tmp/ivytest/build.xml:22: syntax errors in ivy file
