Hi there,

after yesterdays demoCamp in Walldorf i thought i'll give codeRecommenders a try.
So added the updatesite, installed (did not report any errors), restarted.

Now i tried to add the "Recommenders" nature to some projects. Sadly the result is the following:

An internal error occurred during: "Building workspace".
com.ibm.wala.util.debug.UnimplementedError

Any idea what i am missing?
Using Helios SR2, BuildID: 20110301-1815


Here's the stacktrace from the eclipse log:
!ENTRY org.eclipse.core.jobs 4 2 2011-05-26 11:13:34.703

Hi,

great to hear you want to try. Badly, it doesn't work for you and i'm not able to reproduce the error yet.
First of all, did you choose the dev or the head update site? Is that error appearing in every project you add the Recommenders Nature or just for specific ones? You may want to try it for a clean new plug-in project. If it's working there we are very interested in what is different in your other projects and if not, we have to dig deeper what causes that exception. I'll appreciate anything you can provide me to reproduce the error.

Thanks for the quick answer.

>>First of all, did you choose the dev or the head update site?
Dev, thought it might be a good idea to use the more "stable" one Smile

>>Is that error appearing in every project you add the Recommenders Nature or just for specific ones?

I already removed the plugins cause i could not work due to every build failing.
I made a copy of my eclipse folder, installed the recommender plugins and used a clean workspace. New plugin project, add Recommenders nature and et voilà the error is there.

So yes it happens with every project even with new ones.

Hi Michael,

apparently we fail to resolve some elements of your project's class-path for an unknown reason. Unfortunately, I need little more details yet. Can you make the project you applied Code Recommenders on available to me for debugging purpose? The .classpath file may be sufficient to identify potential problems (but a sample project would be better).

If legal doesn't permit, I can instrument the byte-code toolkit to be more verbose for debugging. In any way, it would be great if you could help us hunting down this fault quickly.

Thanks,
Marcel

Hi Marcel,

i just exported the project from the second test (clean workspace, just an empty plugin project, added recommenders nature)

The zip file attached is the complete project.

P.S. Just drop me a message if you need further details. I am glad if i can help Smile

Hi again,

another thing i noticed that morning. (Wanted to debug the case a little to see if i can find something that helps)

If i start my eclipse from within eclipse (i mean just starting a defaul configuration with a little tweaking on the perm gen space setting) i don't get the error. First i thought it is cause of the debug mode. BUT no, it just did not happen (not in run nor in debug)

That makes me quite confused. I know sometimes "bugs" seem to be gone, but they never are. So tried several times. And no luck.

Tried it in the initial instance (my primary work eclipse) the problem is still there and reproducible all the time. So maybe it could be a plugin that interferes. Hmmpfff I had the setting in the configuration to use all workspace enabled plugins and the target plattform is set to running platform.

So what now ?

rgds

Michael

P.S. i think i install a new eclipse, only install the recommenders stuff and then step by step add the rest i need. Lets see where i get with this Smile

Hi Michael,

there is nothing obviously wrong with the project. It works w/o any changes in my workspace. I guess you will promise that your Eclipse setup is standard, right? Smile No tweaks, no special paths to JRE or plug-ins folder, no links on file system level, blanks in paths etc... (I'm just guessing what might cause this fault).

I'll come up with a patched version of the bytecode toolkit that may give us some more hints later today...

Thanks,
Marcel

Hi Marcel,

this was the hint i was looking for. AAAaaaaaahhhhh i am so sorry for the time you spend on that problem. (Also yours Johannes Smile )

After renaming my "[Eclipse]" collection folder to "Eclipse" it worked without a problem. (I did not try the features yet, but i don't get the build job errors any more.)

Again sorry about it.. (I just feel like a dumb beginner Very Happy )

This isn't your fault at all! Would should be able to handle this. It's great to learn what went wrong. I'll try to figure out how we can get around this nasty one for future drops.

Thanks for bringing this up and helping to hunt it down.

Best,
Marcel

Johannes, can you create a test for this issue?
Can you make a guess whether it may appears on Linux Mac too?

We should schedule a debugging session on your machine to track this one down. Unfortunately, I'm flooded until Tuesday morning. Can you schedule a session some time on Tuesday?

Hi Marcel,

i do that on purpose, i mean adding square brakets or special characters to the path of my workspace and or eclipse installation. We had such issues often, so i am sure if it runs on my eclipse and or workspace it should not have that problem.

The funny thing is, that i would never ever have thought of that a "unimplementedError" could have been caused by a not so ususal path.

Normally the procedure of "renaming" my folders to more common names (removoing the special characters) is one of the first things i try Smile Most of the time the errors are in the context of resources not found or similar. So next time ill try it anyway if an "unexplainable" error occurs.

Never the less, we have learned again that an exception might sometimes be caused by something that has nothing to do with the description Smile

By the way i could test/try to reproduce the issue with the dev version on my mac this evening. If that helps .-)

rgds and thanks

Michael

Hi,

i found the problem. No further testing required, thanks anyway.

The Wala plugin is looking for its own location. To do that they convert an URL to URI without checking for characters not legal to URIs like [ or ].
I'm evaluating how this can be fixed to report a patch within the bug report to wala.

I made a quick fix on my own in the wala project and deployed it to our head update site. So we don't have to wait for the wala team including that patch.
You may want to try head instead of dev to test, if the problem is solved now. After updating, the installed version of plugin com.ibm.wala.core should be 1.3.2.201105271446.

'rgds' --> 'ReGarDS' - He's a perfect candidate for the subwords completion engine, isn't he? Wink

If you don't know it already, you should read this blog-post:

Have a nice weekend Wink

Can't say how much I'd appreciate that. Your time and brains is welcome at all times Smile

We have a quite nice range of things we would like to do (code-search, stacktrace-search, extended-javadoc, code-completion, ...). Just tell us what area attracts you most. We'll then spent a few hours to create some ideas where/how to get involved easily.

And we always welcome new ideas - like subwords completion ...

Best,
Marcel
