Hi,

after having solved my previous problem (project-specific settings for O/T were missing), I'm now stuck at getting O/T enabled in my exported product (eclipse neon, not yet SR1).
All required plug-ins are exported and the code for activating teams does not throw exceptions (except for one weird case).
However, it turns out that my roles are not executed. Starting the product from inside eclipse, I have to set the "enable O/T equinox" setting explicitly in the "Run Configurations" dialog.
Is there anything I have to enable for product export in eclipse neon?
IIRC in eclipse 3.* this worked out of the box.

In Neon your product's .ini file should mention either of:
-Dot.weaving=otre

or
-Dot.weaving=otdre


(Which one you use must match to how you compile your code).

This setting is needed for sure. I'd have to look into the code, however, to see what happens if you specify neither.

"Normally" this setting is added when you install a recent version of OT/Equinox, but obviously, that trick doesn't help for a product.

Hi Stephan,

thanks a lot for your help!
I tried that by adding "-Dot.equinox=true" and "-Dot.weaving=otdre" to the vmargs section, but to no avail.
Eclipse starts up the RCP application with the following three O/T-related definitons:

-Dot.equinox=1
"-javaagent:<path-to-eclipse>\plugins\org.eclipse.objectteams.otequinox_2.5.0.201606070956\otequinoxAgent.jar"
-Dot.weaving=OTDRE

However, adding these lines also has no effect.

Ah, there's one more trick that otequinox performs when being installed: it set's it's own start level to 1.
Here's an extract from our p2.inf:
    org.eclipse.equinox.p2.touchpoint.eclipse.setStartLevel(startLevel:1); \
    org.eclipse.equinox.p2.touchpoint.eclipse.markStarted(started:true);


The result of this can be observed in eclipse/configuration/org.eclipse.equinox.simpleconfigurator/bundles.info as s.t. like
org.eclipse.objectteams.otequinox,2.5.0.201606070956,file:/mybundlepool/plugins/org.eclipse.objectteams.otequinox_2.5.0.201606070956,1,true


I think a product can specify start levels for specific plug-ins, right?

Stephan

Stephan,
yes, one can set this in the product definition. However, this still didn't do the trick Sad
I compared the simpleconfigurator's "config.ini" files and made sure that all plugins are the same version and have the same startup run level, but still to no avail. I also updated eclipse to neon SR1, but that still doesn't help.

Hmmm, do you see the following message in the console?

OT/Equinox: ot.weaving=OTDRE


If yes, and still no team activation, you can add more logging using -Dotequinox.debug=OK

If the above message doesn't appear, we'd need to figure out why/how starting of the otequinox bundle fails. Are you able to drop to an OSGi shell from your product?

I don't see that entry Sad the debug option reveals many of the following:

...



Just for reference: Running from inside eclipse with debugging option enabled, log entries like these show up before the !SESSION entry:

I'll try to find some time to get an OSGi shell running in the product -- what can I do then?

Not seeing "OT/Equinox: ot.weaving=OTDRE" (in the console! It's a plain silly System.err.println(..)) would indicate that the otequinox bundle is not started. For this case it would be interesting to know, what the OSGi console says about this bundle. Is it resolved? Is it shown as started? If not started can it be started manually?

Mh, does your product use org.eclipse.equinox.simpleconfigurator at all? (I don't know if it's possible to run equinox without it).

Not seeing "OT/Equinox: registered:..." messages could also indicate that the extension registry is somehow dysfunctional. But if otequinox isn't even started that might be red herring.

If none of this helps, maybe enabling tracing for equinox would tell us more, see debug options like org.eclipse.osgi/debug/startlevel.
For the general mechanism see, e.g., http://www.vogella.com/tutorials/EclipsePerformance/article.html#using-the-build-in-tracing-facilities-of-eclipse

Wonderful, I've got some better error message (at least I hope so...):
I ran the app from the console (with "-console -debug -consoleLog" program args) and the following comes up:

OT/Equinox: ot.weaving=OTDRE


So OT is activated Smile For each of my teams the following error is printed:

java.lang.UnsupportedClassVersionError: OTDRE: Class *****Team was compiled for incompatible weaving target OTRE


So I wonder if the export is somehow broken, i.e. the project specific settings are ignored then?

Just for completeness -- the plugins' states right after the app windows opens are:
org.eclipse.objectteams.eclipse.monitor (2.5.0.201606070956) "OT/Equinox Runtime Monitor" [Starting]

How do you export your product? Via export wizard? Using Maven/tycho?

You may want to add this line to "build.properties" in all projects using OT/J:
javacProjectSettings=true


Similarly (additionally?) the tycho-compiler-plugin accepts
<useProjectSettings>true</useProjectSettings>


HTH,
Stephan

Thanks a million!!!! I'm exporting via the export wizard and that additional line in the build.properties really did the trick!

That's good news! Thanks for confirming.

Now I just need to find a place where this info should be documented for the future...

Maybe OTD could inform or even enforce that setting to be made?
Do I guess correctly, that it's basically the flag which is set when enabling "project specific settings" for the base Java compiler?

maybe the Application.xmi is not a part of your build. You can check this in your build.properties file.
