Custom installation fails to load plugins

[Aleksey Midenkov]

There are numerious error messages for my custom installation (which
is not guaranteedly correct):

kdevplatform.shell: Unable to load plugin named "kdevappwizard"
because not all mandatory properties are set.
kdevplatform.shell: Unable to load plugin named "kdevexecute" because
not all mandatory properties are set.
kdevplatform.shell: Unable to load plugin named "kdevexternalscript"
because not all mandatory properties are set.
...

I found out that there is no `X-KDevelop-Version` property at this check:

94 // the version property is only required when the plugin
is not installed into the right directory
95 QVariant version = info.rawData().value(KEY_Version()).toVariant();
96 if (version.isValid() && version.value<int>() ==
KDEVELOP_PLUGIN_VERSION) {
97 return true;
98 }

(gdb) p info
$2 = (const KPluginMetaData &) @0x7fffffff9c08: {
m_metaData = {
["KPlugin"] = {
["Authors"] = {{
["Name"] = "Alexander Dymo",
["Name[uk]"] = "Олександр Димо",
["Name[x-test]"] = "xxAlexander Dymoxx"
}},
["Category"] = "Core",
...
["ServiceTypes"] = {"KDevelop/Plugin"},
["Version"] = "0.1"
},
["X-KDevelop-Category"] = "Global",
["X-KDevelop-Interfaces"] = {"org.kdevelop.ITemplateProvider"},
["X-KDevelop-Mode"] = "GUI"
},
m_fileName = "/home/midenok/src/kde/kdevelop/stable/kdevplatform.build/plugins/appwizard/kdevappwizard.so",
d = {
d = 0x0
}
}

Where this `X-KDevelop-Version` should be set for each plugin? I only
found it in kdevelopplugin.desktop which is some kind of template and
does not contain real value.

Hi,
You have not installed the plugin. I think most peoople do this, and
then set QT_PLUGIN_PATH accordingly. AFAIK then it works without this
property. It is possible that the property got lost in the desktop ->
JSON transition and is not actually used set any more, which makes it
not work in this case.

Greetings,
Sven
