Possible Duplicate:
Auto refresh eclipse project upon folder update
I have been working with Java projects using Eclipse (both Ganymede and Helios). I have noticed that when I generate a file, for instance if I create and write data to a text file, or if I serialize some objects, then although the file is visible if I search outside of eclipse (i.e. using windows explorer or the places on linux) it is not appearing in my project folder.
If I try and import this file into my project, then Eclipse tells me that I can't do this because the file is already in my project structure. So I have to move the file manually outside of this folder using windows explorer etc and then import it into the eclipse project before I can see it.
Is there a way to make these generated files appear automatically? What ias the reason they're not already doing so?
Thanks in advance
right click on the project -> refresh
or press F5
Refresh your Eclispe project (F5).
If you are writing those files programmatically, you might be interested in either Auto refresh as Beau suggested, or, if you can, switch to the Eclipse IO API if you wish tighter integration with Eclipse, which will directly take care of this.

After using Apache Netbeans 12.1 for some days, today (without touching the installation folders) I tried to create a new project but I got the error message
"Project Folder already exists and is not empty"
NetBeans creates instead a "default folder", that doesn't open automatically in which you cannot create any package or class.
I used to save my projects in a different folder in my hard disk instead of the default one (the one that NetBeans creates inside "Documents") but I've never got any kind of problem.
I deleted all my folders in which I used to have Java projects and i re-installed NetBeans, Java and JDK many and many times (trying different methods like uninstalling from control panel, from uninstall.exe, etc...) but I was not able to solve it.
I started to think that may be a compatibility issue with NetBeans and JDK because I'm not able to create any package or class and also because after the reinstallation I noticed that the NetBeans User Interface changed, like it was a new version of the software (may be not compatible with my JDK yet?).
I'm currently using Windows 10. Thanks for your time.
That means the default project destination folder that NetBeans picking up for you (or you manually) is not empty and has some files inside it. Open the Explorer and create a new folder inside the same directory and select that while creating a Project.
I'm trying to test Eventuate (framework JAVA that implement event sourcing) But I have a huge feature with eclipse, when I imported the project eclipse display the same files a lot of time.
For information the project is a spring-boot project using gradle.
This is a screen shot:
Would do you have an idea why this happens ?
Use the Package Explorer instead of the Project Explorer, and you won't get the second duplicate.

Another R.Java file missing [duplicate]
(5 answers)
Closed 9 years ago.
I opened an android application project called Test Canvas and later cleaned it by
Project > Clean ...
'Bulid Automatically' option was ticked.
Then the R.java file was deleted and it did not regenerated.I tried all the other options mentioned in the questions of stackexchange.But the R.java file remained missing.
One answer said that R.java generation fails because of errors in .xml files.But there were no errors.I'm 100% sure.
Then i created a new android application project which cannot have any issues in xml files.
When i created the new project it didn't came with the R.java file. I tried cleaning and building with different combinations.It still doesn't work.
I am using eclipse Helios
Android API 15
Android SDK Manager Revision 22
JDK 7U25
Can any one help me on this please?
I understand you have tried cleaning the project. What I would like you to do is Build the project and check the console for any errors.
The R.java also doesn't gets generated if the your project contains errors and these errors are clearly mentioned in your console.
Have a look and see if you can resolve your problem.
Try the following
Close and Reopen the project
Ensure your project folder has 777 rights
Use a later version of Android, that triggers a clean build
Check Problems tab, sometimes errors are not shown on the project files/folder, but a error shows up in this tab
Check top to see the amount of memory you have left, sometimes OOM screws things up
Please use a more later version 1.5 is like decades old
Try this.
Open the properties of your Project
Go to the Android Build target of your Application
Just change the from the currently checked one to another version(can be anything, but one that is supported to at least the minSDK declared in the Manifest)
Do a clean build, if your Project has no issues like in your resources like hyphens in draw able names,unrecognized strings,missing dimension values etc ... your Project should generate the R package with the R class

How can i refresh Eclipse Package explorer with java code?
(2 answers)
Closed 9 years ago.
I found 2 links in the forum but neither really solved my problem. I am creating files in the front end and they get reflected only when i manually refresh the project folder in eclipse... Does any other alternative exist to refresh eclipse automatically?
Thanks in advance
Use : Window->Preferences-> General -> Workspace and check Refresh using native hooks and polling checkbox.
I have verified it. Seems like it polls after few seconds.
I am using Window > Preference > general > worskspace setting .
You should refresh eclipse project programmatically. Take a look on the following discussion: how to refresh eclipse workspace programatically?
Once you learn how to implement plug-in that refreshes the project make it to watch your file system an run refresh once your files have been generated.
I was working on a project, when netbeans freezed and closed abnormaly. When i reopend the project was missing, when i checked the netbeans workspace the folder was missing too.
Does netbeans keep a back-up for his projects? Is there any way to recover ?
Yes of course, hoping the freeze has not break the save system.
For file only it's easy :
Right-click on your project/package
Choose Local History -> Revert Deleted
Now if you have drop all the project you can do this (I've tried it has worked for me)
Create a new project with the same name.
Do the trick for files (2 first points)
If this trick doesn't work I fear you have no more Local History and will never get back your files...
