Install the GlassFish 3 server adapter with Eclipse Helios 3.6, I got a problem

When I install the GlassFish 3 server adapter with Eclipse Helios 3.6 SR1 by here. (Take care the third answer, I got the same problem.)

I got the wrong message:

Cannot complete the install because one or more required items could not be found. Software being installed: GlassFish Java EE 5, Java EE 6 1.0.54 (com.sun.enterprise.jst.server.sunappsrv.feature.feature.group 1.0.54) Missing requirement: GlassFish Java EE 5, Java EE 6 1.0.54 (com.s开发者_JAVA百科un.enterprise.jst.server.sunappsrv.feature.feature.group 1.0.54) requires 'org.eclipse.platform.feature.group [3.5.0,3.6.0)' but it could not be found

The main message is requires 'org.eclipse.platform.feature.group [3.5.0,3.6.0)', just like the third answer the way I followed.

Any suggestion ? Thank you.
