We have a 2021-06 based setup minus some M2E dependencies (because Greclipse has conflicts with M2E logback feature and we don't use M2E).

Features removed from the Eclipse product:

  • org.eclipse.m2e.feature.feature.group
  • org.eclipse.m2e.lemminx.feature.feature.group
  • org.eclipse.m2e.logback.feature.feature.group
  • org.eclipse.mylyn.wikitext_feature.feature.group

      </repository>
    </setupTask>
  </version>
</setup:Product>


Scenario 1:
When using that product alone no Oomph features get installed.
Using the installed Eclipse to install "org.eclipse.oomph.setup.feature.group" does not show any addtional missing dependecies beside Oomph setup itself.

Scenario 2:
In addition to the product we make use of a project which defines additional setting and plugins.
After installation we saw the setup tasks not being executed.
Further investigation showed that "org.eclipse.oomph.setup.feature.group" was not get installed but these were:

  • org.eclipse.oomph.setup.jdt.feature.group
  • org.eclipse.oomph.setup.pde.feature.group
  • org.eclipse.oomph.setup.targlets.feature.group
  • org.eclipse.oomph.targlets.feature.group


Again using the installed Eclipse to install "org.eclipse.oomph.setup.feature.group" does not show any missing dependecies and installs without issues.

Scenario 3:
Having added a 
  <setupTask
      xsi:type="setup.p2:P2Task"
      label="Oomph"
      licenseConfirmationDisabled="true">
    <requirement
        name="org.eclipse.oomph.setup.feature.group"/>
  </setupTask>
makes things work again but still additionally installs

  • org.eclipse.oomph.setup.jdt.feature.group
  • org.eclipse.oomph.setup.pde.feature.group
  • org.eclipse.oomph.setup.targlets.feature.group
  • org.eclipse.oomph.targlets.feature.group


I'm wondering what is going wrong... or better why the requirement for the Oomph setup gets missing and other Oomph "stuff" gets installed.
All this done with 1.22.0 Build 5141 and latest from https://www.eclipse.org/downloads/packages/installer (which is 1.21.0 Build 5141).

Note that the generated product catalog has this p2 task in it:
<?xml version="1.0" encoding="UTF-8"?>
<setup.p2:P2Task
    xmi:version="2.0"
    xmlns:xmi="http://www.omg.org/XMI"
    xmlns:setup.p2="http://www.eclipse.org/oomph/setup/p2/1.0">
  <requirement
      name="org.eclipse.oomph.setup.feature.group"/>
  <repository
      url="${oomph.update.url}"/>
</setup.p2:P2Task>
So all products will include at least the Oomph setup feature.

In addition to this, depending on which task are used in the setup, the implementing features of those tasks will also be installed. This information comes from the "enablement" annotations in the Ecore model from which the task is generated, e.g.,

https://git.eclipse.org/c/oomph/org.eclipse.oomph.git/tree/setups/models/JDT.ecore#n7

So if you have a JRE task that needs to be performed, the org.eclipse.oomph.setup.jdt.feature.group will be installed.
