Would you please tell us which eclipse version do you have exactly? I assume Fedora rpms but need your confirmation. Also do you install webtools from rpm or from update site? What is the error you see? Please attach the log file.

Hmm, it looks like you are using webtools from Neon update site instead of RPMs?

Can you try instead to use the RPMs?

It may need to move your "~/.eclipse" directory to disable any plugins downloaded from the Neon update site, for example:

mv ~/.eclipse ~/.eclipse.old
su -c 'dnf install eclipse-webtools\*'
Comment 5 Diamantis Karagkiaouris 2016-09-01 18:24:22 UTC 
It seems to be working now when i installed rpms eclipse-webtools*, but it should be possible to install plugins from marketplace or other repositories. Also when i download the Neon from the project site, everything seems to be working out of the box.
Comment 6 Diamantis Karagkiaouris 2016-09-01 18:28:07 UTC 
Also something that come up recently is that the eclipse ui suffers from missing webkitgtk3. I think that it must be in eclipse dependencies. I use XFCE and it wasn't installed by default

If the RPMs are working for you, I will close this bug. In most cases installing plugins from the market place or third party repo does work, but sometimes it's necessary for us to add patches to a plugin, which is why we prefer users to use the RPM versions of a plugin (when one exists) with the RPM version of Eclipse.
