Eclipse STS svn svn:ignore, not letting me ignore certain files

Question

I'm using Eclipse STS and SVN on Windows. I'm able to check-in/out from STS, no problem, but when I commit from STS I want to ignore generated files like .class, etc. So I'm trying to use the SVN Property tab and setting the property svn:ignore with the following exclusions...

target
target-eclipse
*.class

But when I commit from eclipse, the .class file still get displayed in the Commit dialog. Is the ignore pattern wrong? I tried using /*.class but eclipse won't let me save that pattern claiming the pattern is not valid
