Melange Installation In Eclipse #132
Comments
Apparently, you used a version of melange that requires xtext 2.10 which isn't the one installed in your eclipse (you haven't indicated the version of neither xtext, nor eclipse in your issue :-( ) you can try another (more recent) version of melange which can be used with a more recent version of eclipse. such as update site http://melange.inria.fr/updatesite/nightly/update_2020-11-16/ (or one of the http://melange.inria.fr/updatesite/nightly/ corresponding to your eclipse version) alternatively, you can use a prebuilt eclipse package with melange already installed such as the GEMOC studio (http://gemoc.org/download.html) |
more specifically, if you start from a Eclipse for java developer I strongly advice to install xText from the Help->Install new software... -> (http://download.eclipse.org/releases/xxxx update site where the xxx version correspond to your current eclipse version ) in order to make sure that the tool is designed for this version (Marketplace may not ensure correct versions of the final installation) This method should be preferred whenever possible (ie. for all components available on http://download.eclipse.org/releases/xxxx) |
The website and this repo are scanty on installing melange within Eclipse.
After installing Text from the marketplace, attempts to install Melange, from the same marketplace fails with:
Cannot complete the install because one or more required items could not be found.

So with a standard Java Developer Eclipse, and Text already installed, how does one install Melange, so that the tutorials can be followed?
