Cannot install GWT plugin to Eclipse

My task is to create a GWT project. I want to replicate what is done in this tutorial.

I'm using Eclipse Kepler 4.3, the newest version of the software and for installing GWT plugin I go to Help > Install New Software and I paste there this link: http: //dl. google.com/eclipse/plugin/4.3 (which I believe is the good one because it is for the 4.3 version)

I check all the stuff only without the Android related one, like in this picture, click next,next and wait for installation.

Somewhere in the middle of the installation it pops up a message saying:

Warning! You are installing software that contains unsigned content. The authenticity or validity of this software cannot be established. Do you want to continue with the installation?

I click OK, even if I think here is the whole stuff goes wrong.

After I click OK, the installation goes very fast, maybe because it skips some files. After that I must restart my Eclipse and I start following the tutorial with the StockWatcher.

But when I go to Window > Preferences > WindowBuilder I have only CodeParsing there, there is no GWT, I checked Window > Preferences > Google where I have Web Toolkit > Designer but here is only stuff about Layout, Code Style and Event Handler.

In Preferences > Google > AppEngine I have the file from their website and Preferences > Google > Web Toolkit their file too.

When I try to create a new project, there is no GWT Java Project...

Can anyone help?

It seems plugin installed in eclipse. there is no such GWT java project option. did you find web application project option while creating new project? - bNd
Yes, I can select that kind of project, it creates it but it is full of errors like Syntax error, annotations are only available if source level is 1.5 or greater, I'm using 1.8 - migea
It suggests me to change some stuff back to 1.5, I do that, the errors are gone, but when I try to run it, it fails and gives me this error: Jan 13, 2015 5:12:35 AM com.google.appengine.tools.development.agent.AppEngineDevAgent premain SEVERE: Unable to load the App Engine dev agent. Security restrictions will not be completely emulated. java.lang.RuntimeException: Unexpected exception during cast. at com.google.apphosting.utils.clearcast.ClearCast$CasterImpl.cast(ClearCast.java:385) at com.google.apphosting.utils.clearcast.ClearCast.staticCast(ClearCast.java:252) ... - migea
Do right click ->Properties->Java Compiler->Enable Project Specific Setting-> Set 1.5 or Greater jdk option. and as your second post: app engine should disable if you don't want in project, while creating pure GWT project. - bNd
I've done what you've told me and it goes the same as previous, no errors in classes, but crashes when run. It says that port 8888 is busy, maybe used by another thing, but I went to Task Manager and no app is using that port.. - migea

GWT is no longer featured in Eclipse
