You have a too old version of the tool installed!
Your statement is correct. The platformUiTools.p2f uses the version 0.16.0 The stable new version is 0.17.0 I replaced the old version in platformUiTools.p2f with the new version, and now the install works as described in [2] [2] https://wiki.eclipse.org/Platform_UI/How_to_Contribute#2._Install_the_development_tools
