Hi

My custom JET templates have suddenly started to fail with 7 "The method
hasStaticFeatures() is undefined for the type GenClass" errors.

This is no doubt because I moved the tip of my EMF GIT to the latest
master, picking up

commit 197526f3fa90e8fad36fddd5b0ec4db26369ff11
[418541] Properly handle static features for dynamic feature delegation

However org.eclipse.emf.ecore.codegen is a closed project in my
workspace, so I am surprised that it is being used at all.

My .jetproperties are

<?xml version="1.0" encoding="UTF-8"?>
<jet-settings>
<template-container>templates;@platform:/resource/org.eclipse.emf.codegen.ecore/templates</template-container>
<source-container>jet-gen</source-container>
</jet-settings>

but changing /resource/ to /plugin/ makes no difference.

Since I cannot find any documentation on the significance of the "@"
that I copied from MDT/UML2 maybe my usage is inappropriate, but it
would seem to me that neither setting should be able to use a closed
project.

Is my thinking wrong or is it a Bugzilla?

Regards

Ed Willink

Yes, and that commit clearly includes the new method:

Much of the JET infrastructure is low level and operates without much
knowledge of the workspace. Even if there is a bug, "fixes" might be
considered a bug by someone relying on current behavior. I'm surprised
though if platform:/plugin makes no difference, and I'm not sure you
should expect platform:/resource to look anywhere other than the
workspace, so a fix is most likely one that just makes it fail until you
have such a workspace project open...

In any case, if you want me to have a look, including everything I need
in a self contained zip file...

Hi

https://bugs.eclipse.org/bugs/show_bug.cgi?id=419239 raised.

..../plugin/... works, provided you restart Eclipse after making the
change; it seems the Nature/Builder has a change insensitive cache.
