[ceylon-dev] FYI: SNAPSHOT versions

[Tako Schotanus]

Hi people,

Just a heads up about issue https://github.com/ceylon/ceylon/issues/6127
which is about SNAPSHOT versions. This issue has been completed and we've
just merged the code to master.

The main reason for SNAPSHOT versions is to make sure the modules we
generate during development never conflict with the modules we create for
an official Ceylon release. So during development all modules will have
`-SNAPSHOT` appended to their version to distinguish them from their final
version. (As a side-effect it will also make it much easier to find all
instances of versions when they need to be changed)

But the switch wasn't a trivial one because of the OSGi information we
generate for our modules. Specifically the versions that OSGi supports are
not compatible with the versions we support and use for Ceylon. (We're
mostly compatible with Maven's versioning). So we first had to come up with
a way to unambiguously convert Ceylon versions to OSGi versions.

So please be alert for any strange behaviour you might suddenly be seeing
that might be caused by this change. We tested thoroughly but we might have
missed something.

Also, David will follow up with a mail explaining what you have to do if
you had already installed a version 1.3.1 plugin in your Eclipse.

Cheers,
-Tako

Hi all,
Due to changes in the way OSGI version qualifiers are generated for
Ceylon modules and Ceylon distribution artifacts,
people who have already installed a 1.3.1 development plugin in Eclipse
will encounter problems to update to new components based on the new
SNAPSHOT version.
The reason is that the generated OSGI qualifier will be seen as older
than the previous one. This problem will only happen once, due to the
switch to the new versioning scheme.
The solution is simple: uninstall the Ceylon components, restart, and
install them again, as I show in more details below.
So when trying to update the 1.3.1 Ceylon plugin, you should see the
following screen:
Note that all the bundles from the 'Ceylon IDE Runtime Bundles'
category are shown without the update icon.
If you still click on 'Next', you will get the following error message:
 
So in order to uninstall the previous 1.3.1 Ceylon components, go to
the 'Installation Details' dialog:
 
select the Ceylon components and uninstall them.
Then restart and you will be able to install the new components based
on the last master with the SNAPSHOT version.
Cheers,
David.

Same thing for those who are updating Ceylon IDE for IntelliJ from Jenkins:

https://ci-ceylon.rhcloud.com/job/ceylon-ide-intellij/lastSuccessfulBuild/artifact/out/installation-packages/updatePlugins.xml <https://ci-ceylon.rhcloud.com/job/ceylon-ide-intellij/lastSuccessfulBuild/artifact/out/installation-packages/updatePlugins.xml>

Now that we have snapshots, I can use better version numbers with automatic updates from dev versions to releases.

Old versions looked like this:

* snapshots == 1.3.1-v20161004012345
* releases == 1.3.1-v20161004012345 😕

New versions look like this:

* snapshots == 1.3.1-SNAPSHOT-v20161004012345
* releases == 1.3.1, 1.3.1-1, 1.3.1-2, 1.3.2 etc

If you are using nightly builds, you’ll have to force the IDE to use an ‘older’ version of the plugin (because in theory 1.3.1-SNAPSHOT-v20161004012345 < 1.3.1-v20161004012345):

* download https://ci-ceylon.rhcloud.com/job/ceylon-ide-intellij/lastSuccessfulBuild/artifact/out/installation-packages/CeylonIDEA.zip <https://ci-ceylon.rhcloud.com/job/ceylon-ide-intellij/lastSuccessfulBuild/artifact/out/installation-packages/CeylonIDEA.zip> manually
* go to Preferences > Plugins > Install plugin from disk
 and chose the file you just downloaded
* restart the IDE

This has to be done only once. Automatic updates from snapshots to releases and releases to snapshots will work according to the update repositories configured in your IDE.
As a bonus, we will now have meaningful versions (previously we had 1.3.0-201609301555 instead of 1.3.0-1 for example).
