As part of our workflow, we prefer not to commit any auto generated files from JUCE. This prevents engineers from accidentally making changes to auto-generated files, and also ensures that we don't clutter code reviews with code out of our control.
To get around this, we can just run:
./Introjucer --resave /path/to/project.jucer
This works fine for a machine with a GUI, but on our headless linux build servers, this is what happens:
Well.. It's all just done as one executable for simplicity, but it should be able to survive that. I don't have a headless set-up to try, do you have stack traces for the assertion and the crash?
Sorry for the delay, but I'm just getting back where I can test this fix.
Unfortunately that didn't do the trick. It looks like IntrojucerApp::isRunningCommandLine doesn't get set until after it has passed the check that was added to jucer_AppearanceSettings.cpp. I fixed that little part like so:
class IntrojucerApp : public JUCEApplication
{
public:
//==============================================================================
IntrojucerApp() : isRunningCommandLine (true) {}
//==============================================================================
void initialise (const String& commandLine) override
{
LookAndFeel::setDefaultLookAndFeel (&lookAndFeel);
settings = new StoredSettings();
if (commandLine.isNotEmpty())
{
const int appReturnCode = performCommandLine (commandLine);
if (appReturnCode != commandLineNotPerformed)
{
setApplicationReturnValue (appReturnCode);
quit();
return;
}
}
isRunningCommandLine = false;
But that only led to failure later on in juce::MouseCursor::showWaitCursor():

More generally, it seems that any call to Desktop::getInstance() is going to be problematic.
I am running ubuntu server inside of VirtualBox to test this, just in case that helps with debugging.
