问题
It's really getting annoying and tiresome when I'm working really hard on something I need to complete and then I need to make a few changes to the GUI so I open Scene Builder and it doesn't open up.
I've tried - Closing Eclipse and opening it. - Killing the scene builder process and opening it.
What works - Logging off and logging on and then opening eclipse & the scene builder.
This is starting to make me lose taste in JavaFX. Though I have to use this over Swing.
Also, when I open Scene Builder (from my desktop) it opens up just fine, though when I navigate to my Main.FXML (inside my project). Scene Builder can't be opened. It just does nothing when I open it, and it minimizes.

Even though this question has been asked some time ago, I want to contribute my solution to this problem because it differs from the other solutions and in addition is very simple.
This particular problem happened to me just a few mins ago and all I took to solve was maximizing the actual Scenebuilder window!
- Open the Windows Taskmanager
- Switch to the applications tab
- Right click the SceneBuilder (named: yourFileName.fxml)
- Select 'Maximize'
Description above works for Windows OS, on other OS the corresponding application managing program should do the same.
That worked for me just perfect. No copying and/or overwriting needed.

Its not the perfect answer but it works well. Try doing the following
1.Open scene builder directly from your local drive.
2.Click on File-> Open Recent -> Clear Menu
Then try to open up your fxml. Works fine for me.

I am having the same problem. It appears that either SceneBuilder or IntelliJ IDEA put my FXML file in a state that Scenebuilder can't parse.
You may find it helpful to edit the logging.properties file and reopen the bad FXML file. On windows it's %ProgramFiles(x86)%\Oracle\JavaFX Scene Builder 2.0\app\logging.properties. You can set
.level = ALL
Then examine the file %TEMP%\scenebuilder-2.0.log for clues.
Valid java.util.Logging levels in descending order are:
OFF
SEVERE
WARNING
INFO
CONFIG
FINE
FINER
FINEST
ALL
Also, copy the FXML file to a temp dir. Try to open it there. I did that and it appears to have fixed the problem.

For me, copying the code from the .fxml file that didnt work with scenebuilder to a new (!) .fxml file on lets just say the desktop and then opening that one worked. After I opened the new file I saved and overwrote it back to where it was in my source folder, and it worked just fine from there on.

- Open scene builder directly from your local drive.
- Click on File-> Open Recent -> Clear Menu
