The problem is that the definition of runWizardImpl has been changed and returns Utils::Wizard now instead of void.

I modified code to build it, it installs now, I see the plugin in modules list, it's activated, also in "Options" I see dub executable settings, but I can't understand how to create or open dub project.

[Groterik]

Now, as you installed the plugin you are able to open dub.json as File -> Open File or Project or create new DUB project via File -> Create New File or Project -> Non-Qt Project -> DUB Project. If it fails please check options for DUB executable path.

[drug007]

Probably installation is broken because I can't openg dub.json and can't create DUB project... Well, will keep trying... But DUB was system-wide installed and runs perfectely from CLI...

[drug007]

Ooops, it's funny but I can do it) will be testing it tomorrow. Thank you!

[drug007]

I can open simple DUB project, but when I try to open non-trivial DUB project either it fails due to dub process timeout or it fails in failed assert. But simple project works - and autocompletion, and building/running and even debuging. It's interesting!

[drug007]

When I increased timeout it only fails in assert. will investigate this.

[Groterik]

Please could you specify the assert file and line?

[drug007]

I manage to run one non-trivial DUB project - the problem was dub hanged during getting annotations. When this reason was removed this project opens and so on very well. But another project fails in dubproject.cpp:93. As I understand here

const ConfigurationInfo& s = m_parser->configurationInfo(m_parser->configurationsList().front());

is fetching front element from empty container.

[Groterik]

Thank you, that's very helpful, I'll try to handle this case. But still, why do you have empty configuration list? Could you exec dub build --annotate --print-configs for the project? Is an output list of available configurations empty?

[drug007]

I have empty configuration list because this package is container for subpackages only.

[Groterik]

Oh, ok, I'll fix it.

[drug007]

this project dub.json looks like

{
    "name": "rdpl",
    "targetType": "none",
    "subPackages": [
        "./core/",
        "./service",
        "./utils",
    ],
}

[Groterik]

I did some workaround for the last problem (f978d4076b6500d3221941eb664c830350f7f7dd). So projects that have no configurations are eligible now and are able to show a project tree for subPackages (only for their default configurations). Build configurations are available after manual configuration only (as long as dub build fails with such "none"-typed projects). It is a little bit messy but I could not find another way to do it because it seems impossible to configure QtCreator's subprojects. In conclusion, I suggest to open subPackages separately.

[drug007]

Thank you!
