We’re running into an error in WTP core that is exposed by the Maven WTP integration in MyEclipse 8.5 (.ear deploys with multiple nested lib folders)

This is fixed in a patch to WTP 3.1.2 which *should* work against ME 8.5, but I get an error that a dependency is missing. I’ve seen some Google hits indicating that the way ME manages features causes this as a side-effect, and there was a ‘compatibility-updates’ site for ganymede-based version of ME (7.5?) – I haven’t found anything equivalent for 8.5.

Here’s the error from Pulse:

 Software being installed: MyEclipse 8.5 (Profile) 2.0.0.0000000016 (com.poweredbypulse.profile-607439-rmb-736267 2.0.0.0000000016)
  Missing requirement: WTP Patches for org.eclipse.jst.web_core.feature 3.1.2.v201003170515-20Bi7w312115242715 (org.eclipse.jst.web_core.feature.patch.feature.group 3.1.2.v201003170515-20Bi7w312115242715) requires 'org.eclipse.jst.web_core.feature.feature.group [3.1.1.v200908121609-7S7CG-dFIhIeq7kV6qxaLD]' but it could not be found

    To: org.eclipse.jst.web_core.feature.patch.feature.group 0.0.0

Any assistance would be appreciated. Here’s a link to the M2E JIRA issue related to this:

Thanks,

Can I provide any additional information to get assistance with this? What’s this elusive “feature.group” feature that’s requested whenever an installation is attempted?

Thanks,
Brice

Brice,

I have escalated your issue to dev team member, they will get back to you on this.
Sorry for the inconvenience.

Thank you for the response. I have seen some other posts relating to missing ‘feature.group’ requirements and was hoping there was a simple solution, but I guess not 😉

Brice,

With MyEclipse 8 we changed the way we build and distribute MyEclipse by actually shipping the WTP features that we integrate into MyEclipse. Earlier versions (pre 3.5 / Galileo) would not ship these features and hence the patch site was required for users who needed to install third party software that required these features. By shipping the features we meet requirements of most 3rd party plugins.

What is happening here is that we have rebuilt the WTP feature in question – org.eclipse.jst.web_core.feature from source and we have the same version 3.1.1 – but a different qualifier. The WTP patch is unfortunately hard bound to their qualifier and so will not work with MyEclipse. I will look at whether we can fix this in the upcoming 8.6M1 release, but am unsure if this will make the cut. If you wish to apply this patch, you can download their patch and manually “loosen” the required range such that it can be applied on MyEclipse.

Sorry I could not be of more assistance, but if there is any more info, I will let you know.

[bdr011]

Sure, I can try that. Can you provide me with some assistance on what I need to change? Thanks.

Brice,

On further investigation of the patch, I noticed that if applied, it would overwrite important changes that MyEclipse made to the patched plugins, causing further breaks in functionality. So even if you loosened the requirements and applied the patch, the end result would be problematic.

I have pulled the changes made by these patches back into 8.6M1 (due next week). The WTP component of 8.6M1 will already have this functionality changed and you will not need to apply any patches.

[bdr011]

OK, I’ll await the 8.6M1 release

Brice,

You can download 8.6 M1 from http://www.myeclipseide.com/module-htmlpages-display-pid-4.html
