Hello Guys,

I tried to import the project according to http://www.globalqss.com/wiki/index.php/IDempiere/Setting_up_Eclipse ,and  I have the following error when i do

'Materializing iDempiere project within Eclipse' step.

My system environment:

Windows 7

Eclise  Juno Service Release 2

jkd 1.6.0.22

HI Aoslee,

Use Indigo, and see if the issue persists. The last time I know, iDempiere still have problem with Juno. Don't know if somebody have done any work on it.

Hi Hiep,Edwin:

 I changed  juno to indigo and I still get that error message.So I think it is main reason.

 I retry all steps according to http://www.globalqss.com/wiki/index.php/IDempiere/Setting_up_Eclipse,

and I get successful finally.

The following message in http://www.banym.de/eclipse/build-the-idempiere-project-using-eclipse-with-buckminster is what i say all.
"Daniel T wrote:
Finally I got it working after reading the instructions on Carlos wiki.DON’T clone the idempiere-repo from inside eclipse. That was my problem. If the idempiere repo is cloned from within eclipse, it automatically tries to add all the subprojects in the repo.
SO:
FIRST clone the repo outside of eclipse.THEN materialize using Buckminster in eclipse.The versions of Eclipse and Buckminster doesn’t seem to be a problem. Posted 01 Apr 2012 at 9:01 am "

Thanks for your reply.

best regards

Hi Everyone,

I am not able to materialize iDempiere in anything but Indigo Eclipse. Both Juno and Kepler failed with the "Java.lang.NoClassDefFoundError: org/eclipse/pde/internal/core/target/provisional/ITargetPlatformService" error. Here are the details:

• Microsoft Windows Server 2008 R2 SP1 Datacenter 64-bit Locale English Base AMI provided by Amazon
  
• Tried materializing directly from iDempiere clone.
• Tried materializing from a clone of a clone.
• Tried materializing from a downloaded copy of the code from 1.0C tag.
• FYI - no clones were made from inside eclipse

The only thing that always works is materializing from indigo. Does anyone have any insight?

Hi Everyone,

I figured it out. Eclipse Juno and Kepler require a newer version of Buckminster. Most of the tutorials out there call for http://download.eclipse.org/tools/buckminster/updates-3.7. With Kepler, you probably should install http://download.eclipse.org/tools/buckminster/updates-4.3. It just magically works when you install the newer version.

I hope this helps!

thanks Chuck

the error raised with Kepler, once I installed Buckminster  http://download.eclipse.org/tools/buckminster/updates-4.3, the error was solved.
