1. Acceleo solution from an Acceleo update site,
   
2. Acceleo required dependencies from the Papyrus Add-ins update site
   
3. and finally the Ada 2005 Code Generator from the Papyrus Add-ins update site.
   

Hi all,

I have faced the following issue when trying to add the Ada 2005 Code Generation add-in into a vanilla Papyrus-1.12.3 installation (Linux, 32bit, latest "official" 1.6.0_24 Java):

  Cannot connect to keystore.
  This trust engine is read only.
  Cannot complete the install because one or more required items could not be found.
    Software currently installed: ADA 2005 code generator for Papyrus 1.0.1.200911231214 (com.adacore.uml2ada2005_feature.feature.group 1.0.1.200911231214)
    Missing requirement: com.adacore.uml2ada2005 1.0.1.200911231214 (com.adacore.uml2ada2005 1.0.1.200911231214) requires 'bundle com.cea.papyrus.integration.acceleo 1.2.0' but it could not be found
    Cannot satisfy dependency:
      From: ADA 2005 code generator for Papyrus 1.0.1.200911231214 (com.adacore.uml2ada2005_feature.feature.group 1.0.1.200911231214)
      To: com.adacore.uml2ada2005 [1.0.1.200911231214]

I think, that keystore is not a problem here. I have also both the CDT Gallileo and the Acceleo update site configured, as suggested on the Add-ins donwload site. I would expect, that if the dependencies are possible to satisfy, the update manager would just pick them.

I was also trying to install manually the "Acceleo integration plugin for Papyrus" plugin in, but this fails with the another missing dependency:

  Cannot connect to keystore.
  This trust engine is read only.
  Cannot complete the install because one or more required items could not be found.
    Software currently installed: Acceleo integration plugin for Papyrus 1.2.0 (com.cea.papyrus.integration.acceleo.feature.group 1.2.0)
    Missing requirement: Acceleo integration inside Papyrus 1.2.0 (com.cea.papyrus.integration.acceleo 1.2.0) requires 'bundle fr.obeo.acceleo.chain 0.0.0' but it could not be found
    Cannot satisfy dependency:
      From: Acceleo integration plugin for Papyrus 1.2.0 (com.cea.papyrus.integration.acceleo.feature.group 1.2.0)
      To: com.cea.papyrus.integration.acceleo [1.2.0]

Am I missing something?

Thanks in advance! Piotr.
