1. install liferay-ide and restart eclipse
2. install latest bndtools(maybe 3.2 release version)(https://dl.bintray.com/bndtools/bndtools/latest/) and restart eclipse
3. open "Install Details" windows and switch "Plug-ins" tab and input "bnd" and it will just show bndtools releated bundles and you should make sure the version of the plugins is the one you just installed not the one included in liferay-ide.(just see 3.2 version and can't see 3.1 version)
4. the same with buildship.
