I can´t install Epsilon in Obeo Designer 11.0 [message #1797785]

Hi everyone,

I need install the Epsilon 1.5 plugins for my Obeo Designer 11.0 but the wizards can't complete the installation. I attach an image of the problem. Any idea to solve the problem?

Thank you so much,

Cristian.

Hi

You have provided a screen shot of the useless 'solution' rather than a copy and paste log of the original problem so it is hard to know what your problem is.

I have been using Epsilon 1.5 on recent platforms with only a minor testing problem [1]. But I think that it is very unlikely that this would cause an install problem.

Hi

Once again you have provide an inadequate screen shot showing just two levels of the error message. A copy and paste would show all and allow me to copy in turn.

From what you show it would appear that XSD is missing suggesting that you have a limited EMF install and have not permitted the install to search for more either by allowing contact all sites or by providing a useful EMF site.

Correction: I have been successfully using 1.5.0. It appears that 1.5.1 has silently displaced 1.5.0. Epsilon does not provide versioned update sites.

Hi,

I solved the problem by following these installation steps in order:

Eclipse Photon Repository: http://download.eclipse.org/releases/photon/ (Install: Equinox Target Components)
GMF Tooling: http://download.eclipse.org/modeling/gmp/gmf-tooling/updates/releases/ (Install: Graphical Modelling Framework (GMF) Tooling SDK)
Epsilon 1.5.1: http://download.eclipse.org/epsilon/updates/

Thank you so much,

Cristian.

Hi

Your problems prompted me to look at Epsilon/QVTo/GMF Tooling issues and it appears that having got past your installation problem you will soon hit the NPE during GMFgen problem.

GMF Tooling unfortunately uses internal QVTo API, which the QVTo project has twice evolved (in 2013 and 2016) breaking GMF Tooling on each occasion. You must therefore use an old version of QVTo to match the old version of the see,mingly dead GMF Tooling project.

However, since GMF Tooling is clearly still in use, I was inspired to try and re-instate the internal APIs and avoid the need for an old QVTo. See [1]

If you download and try

https://hudson.eclipse.org/qvt-oml/job/qvto-branch-tests/70/artifact/releng/org.eclipse.qvto.releng.build-site/target/org.eclipse.qvto-3.9.1.N20181109-1902.zip

you should find two API breakages re-instated. Once we have confirmation that this makes GMF Tooling useful again we can look to include the fixes in the next QVTo release.
