plug-in jar remains same during uninstall and reinstall [message #336784]

Hi,

I have two installations of eclipse-3.4.2. One for development of our
plug-in and another for testing the same.
This is what happens :
I install our plug-in on eclipse-3.4.2. And after a couple of quick tests
I uninstall it.
Then I do some changes to the plug-in and build fresh plug-in update site
by following this method :
http://wiki.eclipse.org/FAQ_How_do_I_create_an_update_site_(site.xml)%3F
I install the plug-in again on the test-eclipse-installation and test out
the features. But I don't find the latest changes in the plug-in. I don't
even see the simple println statements.
Also, when I check the creation date of plug-in jar it clearly tells me
that the jar present in eclipse/plugins is old one.

How do I solve this problem?

Thanks.

I'm not an expert. I think that the 'right' thing is to increment the
plugin version number, so that eclipse knows it is changed. If Eclipse
had the possibility to see changes in the content of the plugin without
different plugin version, it should download every plugin installed at
each update command (if you have automatic updates, this can be really
expensive).

If there is another way, I'm very intereasted too, since everytime I put
on my update site a new version, and there is a little bug (like a
NullPointer...), I dislike very much to increment version number just to
update clients...

As mentioned, you need a higher version number. most plugins have a
version similar to:
Bundle-Version: 0.9.0.qualifier

qualifier gets replaced on build, and can be replaced on a
File>Export...>Deployable plugin and fragment as well.

Most qualifiers look like: v20090629 or I20090629-1930

To make sure plug-in sources are updated between uninstall and reinstall I
realized that I had to change the version number.
To do so :

I added the qualifier in plug-in's MANIFEST.MF as :
Bundle-Version: 1.0.0.v200908041905

Then I created update site by following steps in this document (just as I
do normally and works great):
http://wiki.eclipse.org/FAQ_How_do_I_create_an_update_site_(site.xml)%3F

Problem :
This added another plug-in jar to update-site/plugins directory apart from
the old one with just 1.0.0 as the version number.
A new unit with this version number was added to content.xml.
Also a new artifact was added to the artifacts.xml.
The size of our final zip (of update-site dir) has obviously doubled!
Deleting old jar manually before zipping up doesn't solve the problem as
old entries of 'unit' and 'artifact' remain in the xml files which are
then searched for during installation. And installation halts on not
finding them.

Am I doing something wrong here while adding a qualifier to the bundle
version?
If yes please tell me what is the right way of changing version number of
plug-in jar.

Thanks.

Adding the qualifier allows update (now p2) to know that bundle needs to be updated. So adding v200908041905 to the MANIFEST and jar name solves that problem when deploying your site?

Is the problem now that your deployed site is twice as big because it has the 1.0.0 version as well as the one with the qualifier? If you are deploying from eclipse, it should be possible to delete the 1.0.0 version from your site project and/or site.xml and re-deploy the site ... no?
