创建项目时出错 - Eclipse

I am trying to to setup Xdebug with Eclipse for the purpose of looking at how Wordpress works by stepping through code. I have successfully installed

  • XAMP 2.5 (Apache and MySql)
  • Wordpress 3.7.1 locally.
  • Xdebug 2.1.1
  • Eclipse Version: Kepler Service Release 1, Build id: 20130919-0819 (64 Bit)
  • JRE 7 (64 Bit)
  • PDT (PHP Development Tools)

When I do File -> New -> PHP Project I get

Problems encountered while setting project description.
Error configuring nature 'org.eclipse.php.core.PHPNature'.
org.eclipse.dltk.core.IBuildpathEntry.isContainerEntry()Z

What does this mean? How do I fix it?

I have the same problem and fix it right now. I think the reason is that some components are not compatible with others. Try to download PDT again: http://download.eclipse.org/tools/pdt/updates/3.3. If eclipse shows PDT is installed, delete it first from Help->About Eclipse->Installation information->Find PDT and uninstall.
