Created attachment 135852 [details] stacktrace
Could you tell us a bit about your directory structure? Where exactly are you trying to create HTML5 project? From the exception it looks like the folder you are creating HTML5 project in already has a makefile and the C++ support project gets into conflict with HTML5 about ownership. I would think that C++ support for makefiles is at wrong here and should have reported the folder earlier to prevent HTML5 project from re-using the folder. Tomas, what's your opinion on this issue?
Hello... I have CMake-based C++ project, and inside it i have the "html" folder with HTML application. Exception occured when i try to create HTML5 application with root in the "html" folder. C++ project was opened at this moment... (In reply to comment #2) > Could you tell us a bit about your directory structure? Where exactly are you > trying to create HTML5 project?

Tomas, could you look into it please?
AFAIK, this scenario is not supported - see [1]. We already had a similar issue for PHP support - see issue #224799. I will improve the wizard. Please, let me know if I am wrong. Thanks. [1] http://wiki.netbeans.org/FaqSourceRootOverlap
So it seems that I was wrong and nested projects are (generally) supported so please ignore my last comment... However, I am not able to reproduce your issue - I can create an HTML5 project in an existing project (PHP project in my case) without any problem... Could you please try it once more? Or are there any exact steps I have to do? Simply reopen this issue. @mkleint: In any case, the problem seems to be in AntProjectHelper.createProject() - it should return the newly created HTML5 project and not C++ project (but as I wrote, it works for me properly). Miloši, can you confirm that? Thanks.

Miloši, > can you confirm that? Sorry, not precise. The code is: AntProjectHelper projectHelper = ProjectGenerator.createProject(dirFO, ClientSideProjectType.TYPE); setProjectName(projectHelper, name); ClientSideProject project = (ClientSideProject) FileOwnerQuery.getOwner(dirFO); The problem is on the last line, C++ project is returned and not the HTML5 one. Thanks.

The code is: > > AntProjectHelper projectHelper = ProjectGenerator.createProject(dirFO, > ClientSideProjectType.TYPE); > setProjectName(projectHelper, name); > ClientSideProject project = (ClientSideProject) FileOwnerQuery.getOwner(dirFO); in any case, you should never cast the project. it could be also the FeatureOnDemand proxy one.. use project.getLookup(ClientSideProject.class) or some similar pattern. The problem here could be not primary related to nesting existing projects but creation of a new project within an existing project. I'm sure it would work the other way around, when creating the html project first and then create a C++ project around it. You might want to consider calling ProjectManager.clearNonProjectCache() before attempting FOQ.getOwner() Also please note that C++ projects have a different definition of what belongs to the project (their config files contain a list of files belonging to the projects, so they likely have their own FOQImplementation that reports ownership based on their config file). Has the html folder been included in the c++ project? > > The problem is on the last line, C++ project is returned and not the HTML5 one. > > Thanks.
Thanks a lot Miloši for your comment, I will do the changes in HTML5 project code. (In reply to comment #8) > Has the html folder been included in the c++ project? This must be confirmed by reporter, I have no idea (so keeping resolved as INCOMPLETE). Thanks.
(In reply to comment #9) > Thanks a lot Miloši for your comment, I will do the changes in HTML5 project > code. Done. http://hg.netbeans.org/web-main/rev/50f29c90cca3

Please provide step by step instructions how to reproduce this problem from scratch. I tried it myself and it always works for me - I can create HTML5 project from existing sources for html files/folders from a C++ project. Thanks.

I've attached simply test project, for reproducing bug you need CMake, so steps are simply: 1) using cmake configure project with build directory "build" 2) in NB create "C++ project with existing sources" and select "custom" configuration mode 3) check "run configure script in subfolder", in textfield input "build", all other steps select default parameters 4) try to create html5 project with "html" folder as root - you will see exception...

Thanks, I can reproduce it now. It looks to me that cnd.makeproject/src/org/netbeans/modules/cnd/makeproject/MakeProjectFileOwnerQuery.java claims any file under C++ project root to belong to C++ project.
(In reply to comment #18) > It looks to me that > cnd.makeproject/src/org/netbeans/modules/cnd/makeproject/MakeProjectFileOwnerQuery.java > claims any file under C++ project root to belong to C++ project. Yes, this is what Miloš wrote in comment #8. IMHO bug in CND, not HTML5 project. Thanks.
Reassigning to CND - please evaluate (see comment #18). Thanks.
It is true: all files in C/C++ project source root belongs to C/C++ project. To create nested project add nested source root folder in ignore folders pattern in parent project properties.
(In reply to comment #21) > It is true: all files in C/C++ project source root belongs to C/C++ project. > To create nested project add nested source root folder in ignore folders > pattern in parent project properties. that's counterintuitive and makes c++ projects stand out. What was the reason for breaking the behaviour shared by other project types? (overriding the SimpleFileOwnerQueryImplementation behaviour)
(In reply to comment #22) > that's counterintuitive and makes c++ projects stand out. What was the reason > for breaking the behaviour shared by other project types? (overriding the > SimpleFileOwnerQueryImplementation behaviour) Simple answer: SimpleFileOwnerQueryImplementation does not fit CND FOQ requirements (project folder can be different with source root). By the way I do not see nested project problem except HTML5 project.
So, is it possible to fix this issue? (In reply to comment #23) > (In reply to comment #22) > > that's counterintuitive and makes c++ projects stand out.

re. "is it possible to fix this issue?" - this was answered by Alexander in comment 21: "To create nested project add nested source root folder in ignore folders pattern in parent project properties."
