Re: Eclipse 4 and p2

[Lars Vogel]

You mean http://www.vogella.com/articles/EclipseP2Update/article.html, right? Is your repository location correct?

Hi
iam try to develop a eclipse 4 rcp p2 and your tutorial--> Eclipse p2 updates for RCP applications  was very useful but there is a NullPoinerException at class:

P2UpdateHandler.java

line: operation.getProvisioningJob(monitor).schedule();

It seems that operation.getProvisioningJob(monitor) returns null

I thank you for your good tutorials.

Best Regards!

Are you running the update process from an exported Eclipse RCP application? This update does NOT work from an RCP application which is started via the Eclipse IDE.

I'm seeing exactly the same - yes i'm following the instructions you provided on the link you've given there.

i've tried a file:/// repository and i've also tried putting the repository onto a local webserver and pointing it at that - but that line ALWAYS returns null.

Any ideas?

Thanks for the response, Lars,

I worked out that it needs to be run from an exported application, but it still wasn't updating. I finally got it working by switching to using a an product specification based on features and using the p2.rcp.feature - this works, downloads updates from the remote site and all is well. 

[Lars Vogel]

Sounds like you are using an Eclipse 3.x application because AFAIK the p2.rcp.feature does not work in Eclipse 4. I assume this was also the problem.

ah ok. i was convinced i was using 4.2

i aren't in front of the project right now but will check

thanks

[Lars Vogel]

You may be using Eclipse 4.2 to develop an Eclipse 3.X RCP application. If you can switch I highly recommend that: http://www.vogella.com/articles/EclipseRCP/article.html

Thanks Lars, unfortunately the latest stable builds of 4.3 for mac seem unavailable.

I'll try again later

Thanks again for your help though, much appreciated
