Bug 269822

The IDE probably just does not "know", which file is the result of your build. In the case of managed project (i.e. when you choose "Application Project", "Dynamic Library" or "Static Library" when creating your project) IDE knows everything about your code. If you choose "project from existing code" or "project from binary", IDE probably just do not know what's the result of the build, so it does not know what to download.

If that's the case, then please go to Project Properties, choose "Build > Make" in the tree to the left, and fill "build result" field. IDE then will prompt tp download this file after build.

I see that indeed strange things happen with downloading changed files in 8.2. I think I'll fix this in an upcoming patch.

Information from you is valuable, however. 
I'd like to know
1) whether you project is managed or based on a custom makefile
2) if it's based on a custom makefile, then please check whether build result is filled properly.

Otherwise I can solve problems that I see with download (they are different from yours), but not your problem.

There is another thing that can prevent downloading files. In brief, IDE stores information concerning changed files downloads in the file 
nbproject/private/downloads-${host}-${user}-22
This file might get corrupted. 
As a workaround try to do the following:
- quite NetBeans
- remove this file
- restart NetBeans and try again

No Build>Make

Hi,
first of all there is no Build>Make options (see attachment). This screenshot  is BTW from a minimal "Hello Raspberry Pi" application, that I created with default settings exactly to see if there  a problem with project settings, but the downloading still doesn't work. All my projects are managed by Netbeans.

I probably should have mentioned, that some of the projects are Qt based. And biggest problem with the bug that the files that are generated by moc and especially by uic during building are not  downloaded. Therefore Netbeans can't provide code assistance for them, which is very inconvenient.

Also there is no downloads-*** file in all folders.

No. By design in most cases on local host user hasn't any compilers. IDE parses files on "remote host". You key problem you uses Linux-ARM. On Linux-ARM you needs configure project by hands,

Such scenario works nicely:
- Add Raspberry Pi host in SFTP mode
- Create "Hello Qt World" project
- Build project
==> "Download HelloQtWorld_2, moc_HelloForm.cpp and ui_HelloForm.h" wizard appears

I did similar thing for similar purposes, the projects builds alright, but I see no dialogue.

Do you need any extra information?

I installed Netbeans 8.0.2 that I had used before upgrading to 8.2 to see if it would  work better.
Not really, but playing around with them I found something interesting: in both versions some older projects still get downloaded, but new new ones don't

Is there an option/setting that controls this behavior?

While investigating this and some other complaints I found a number of related problems and filed an issue 270157 with implementation-wise description of the problems found.

I've just fixed issue 270157. I think this one is resolved as well by these fixes.

I think Monday (Mar 27) morning the will be available in NetBeans daily builds; I encourage you to try it.

I tried the build 201703280002 and in the process of trying it I found out that the problem is in a space that I have in the name of an upper level folder. If it is removed, the downloading works, even in stable 8.2

You are right, this is easily reproduced with a path that contains space - even after my recent fixes.

fixed, change sets 7dbc8d5cfa4e and dfc41470b9ec on enum

I tried build 201704100002, but it doesn't work. Is the fix not yet integrated?

Integrated into 'main-silver', will be available in build *201704110002* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
