How to upgrade a development environment
In order to prepare a new development environment you should find
- the latest version of Eclipse
- the latest version of Xtext
- any new version of Xpect
As a rule of thumb, we always prefer Eclipse for Java Developers because Eclipse DSL environment has older versions than recreating the environment manually.
- you can refer to the Jenkins nightly build, this is the main page
Eclipse uses p2 repositories which contain bundles of jars, and Wollok uses Tycho as a plugin for using those p2 repositories in a target platform and generate the final product (so you don't have to sync Maven and p2 repositories).
So, if you want to succesfully build a product, you must look for the latest bundles and the right p2 repositories (common failure is that you are looking for a newer version of a component in an old repository, or you try to use two versions of the same component)

You can point to this commit as the first step to collect the files you should review whenever you want to upgrade.
-
org.uqbar.project.wollok.targetplatform/org.uqbar.project.wollok.targetplatform.target
In this target platform file you locate p2 repositories and bundle jars, specially Xtext, EMF (Eclipse Modeling Framework), MWE/MWE2 (Modeling Workflow Engine), Xpand & Eclipse components (like SWT, GEF), and also JUnit, Xtend, EGit, Xpect... You must take care of locations & versions, based on this recommendations.
To accomplish that you should take a look at Eclipse Bundles Migration Support (here's an example of a previous one). You'll find there FAQs, incompatibilities,a and advises for migrations from latest version to the new one. If you are upgrading from 4.8 to 4.12, you should take a look at 4.9, 4.10, 4.11 & 4.12 release notes.
