The parent project dir doesn't have target dir & eclipse files ignored, none have idea and netbeans ignored.
It's nice to have intellij idea and netbeans files excluded too.
The svn:ignore property should be equal on every folder that contains a pom.xml: parent pom dir, module pom dirs etc.
Here's an advisable list, it includes the build map, and project configuration of eclipse, idea and netbeans,
and a local map, which is handy for a notepad.txt file etc
