I create a own Setup Task. But now when I try to use it in a new Installation (other PC without any Eclipse) I get the following exeption.

!ENTRY org.eclipse.oomph.setup.installer 4 0 2020-06-19 12:02:09.051

I checked that the repository URL ant the feature Name are correct.

How can I see if the Problem is within my Setup Task?

The buttons are created conditionally:
    offlineProperty = PropertiesUtil.getBoolean(SetupProperties.PROP_SETUP_OFFLINE);
    if (offlineProperty == null)
    {
      offlineButton = buttonBar.addCheckButton("Offline", "Avoid unnecessary network requests during the installation process", false,
          "toggleCommand:org.eclipse.oomph.ui.ToggleOfflineMode");
      AccessUtil.setKey(offlineButton, "offline");
    }

    mirrorsProperty = PropertiesUtil.getBoolean(SetupProperties.PROP_SETUP_MIRRORS);
    if (mirrorsProperty == null)
    {
      mirrorsButton = buttonBar.addCheckButton("Mirrors", "Make use of p2 mirrors during the installation process", true, "mirrors");
      AccessUtil.setKey(mirrorsButton, "mirrors");
    }
But that suggests that org.eclipse.oomph.setup.ui.EnablementComposite.enableButtons(boolean) should guard against these things being null.

Did you set these properties such that the buttons aren't being created?

I only see the Offline checkbox but the checkbox is disabled.
I can not see a button or Checkbox for Mirrors.

How can I set the SetupProperties.PROP_SETUP_OFFLINE and SetupProperties.PROP_SETUP_MIRRORS property

If you want to look more closely at all the code and to be able to debug launch the installer (there are launchers in the projects available), you can use this:

https://www.eclipse.org/setups/installer/?url=http://git.eclipse.org/c/oomph/org.eclipse.oomph.git/plain/setups/configurations/OomphConfiguration.setup&show=true

That would also allow you to commit changes to Gerrit to fix problems.

That particular property is defined like this:
  public static final String PROP_SETUP_MIRRORS = "eclipse.p2.mirrors";

So I suspect you have this set to true or false to make that button not appear and to use that default setting instead.

Now I found my problem.

For some reason I add a wrong Definition to the vm Argument.
-Declipse.p2.mirrors=false

This removes the Checkbox and not the usage of mirrors.

Actually, setting it to false (anything non-null other than true) not only hides the button but makes it behave as if there were a button that's unchecked.

The fact that there is an NPE is definitely a bug. Please open a Bugzilla for that.

OK,
I will do this over the Weekend in my private time and will contribute a fix.
