NullPointerException when using Ant task

[maartenc]

Hi,

when we try to use the macker 1.0.2 Ant task, we get the following NullPointerException:
java.lang.NullPointerException
at de.andrena.tools.macker.rule.RuleSetBuilder.(RuleSetBuilder.java:71)
at de.andrena.tools.macker.Macker.addRulesFile(Macker.java:230)
at de.andrena.tools.macker.ant.MackerAntTask.addConfiguredRules(MackerAntTask.java:205)

This used to work with macker 1.0.1, so I guess your last change caused a regression.

kind regards,
Maarten Coene
