Periodically (during autosave) and at close i get:
Problems saving workspace
(X) Problems occurred while trying to save the state of the workbench.
Details >>
Could not write metadata for '/projectname'.
encoded string too long: 123456 bytes
Can't find a reason or solution for this using the usual means. Any ideas how to fix?
THis is using eclipse 3.4 (Ganymede)
It should relate to a bug in DataOuputStream that it cannot writeUTF with longer then 65535 utflen.
If I were you, I will try to find a way to reduce the data size, and I will submit bug report to Eclipse and JRE.
Started having the same issues under Vista x64. The latest JRE appears to not have the same DataOuputStream limitation so installing it fixes the annoyance.
An observation I've made about these occurrences for me is that they only occur on newly created projects during the same Eclipse session that I created the project. Once I restart Eclipse, I don't see the issue again until the next time I create a new project.
Has anyone else noticed this about the occurrences of the error for them?
It's not a write permissions or disk-space issue. I'm getting the same problem on Eclipse 3.5 M4. No troubles with 3.4.1.

All of a sudden the code completion and suggestion (for example when typing the . operator listing the possible methods on an object, etc.) is very slow, also fixing imports. Restarting the IDE didn't solve it.
I cannot see any other task NetBeans is running.
What can be the cause?
Is it because the update to 12.4 is coming up and NetBeans gathers some data or metrics :)
Otherwise the IDE is working normal, quick as usual.
Check if the performance is same when you deactivate your antivirus
Check in the About window of NetBeans where your cache directory is located and rename/delete it
You can try it with most recent release 12.4. It's not yet published on their website but you can download it anyway: https://www.apache.org/dyn/closer.cgi/netbeans/netbeans/12.4/netbeans-12.4-bin.zip
I'm trying to install Netbeans 8.2 Java EE, but whenever I start the installer it quits after configuring it. I am trying to install it on Windows 10 64-bit.
This is not going to make sense at all, but do you happen to have the "God Mode" item on your desktop? Take it off the desktop (delete it, move it somewhere else, whatever). I have no idea why, but it worked for me: I found the solution in this bug report - https://netbeans.org/bugzilla/show_bug.cgi?id=269988
I do hope this helps you, too.
This is an Java issue, which was came up due to recent windows 10 update, that started treated differently for GodMode folder/shortcut.
This has been already fixed - https://bugs.openjdk.java.net/browse/JDK-8179014
You can verify the fix in early access build of JDK8 update 152, which is available here
We have verified the issue only with GodMode, do let us k now if there are any other scenarios that can cause such similar issues.
I'm adding this because: I had a different issue which I was unable to find addressed anywhere, this question appears near the top of a web search for "NetBeans 8.2 ee won't install on Windows 10", and someone else may have the problem I had.
My NetBeans install was almost immediately crashing with the following error:
An unexpected exception happened in thread main
Exception: javax.xml.parsers.FactoryConfigurationError: Provider for
class javax.xml.parsers.DocumentBuilderFactory cannot be created
In my Windows 10 System Properties -> Environment Variables -> System Variables, I had a previously created _JAVA_OPTIONS variable values using -Xbootclasspath/a to append some jar files to the end of the bootstrap class path. These files are used with some work I'm doing with the Oracle BI Publisher plug-in for Microsoft Word.
As soon as I renamed the _JAVA_OPTIONS variable to something else, my NetBeans installation started normally and completed with no issues.
After NetBeans installation, I reset the name of this variable back to _JAVA_OPTIONS, and discovered that the values I have for this System Variable cause NetBeans launch to crash. (Which does not completely make sense to me since I am only appending these files/classes to the class path, and not overwriting.)
Regardless, I'll have to go back to the drawing board for my work with the BI Publisher plug-in; but at least I can use NetBeans now!
Uninstall any Java installations along with NetBeans, and install Java with NetBeans (bundle) from the Oracle website.
I had the same issue, and then installed the bundle, works perfectly.
When I go to the "Boot Dashboard" (Update: actually I see similar messages on each Spring view) view I see the message
Could not create the view: org.springframework.ide.eclipse.boot.dash.views.BootDashView
There is an icon to see the error logs beside it, so I deleted them, reopened STS, and I did not see any error.
Any guidance on how to resolve this or further debug it?
More info
After following Martin's advice and opening the Host OSGi Console and typing ss to get the short status and doing diag <id> on a few different things all I was ever able to get was similar to this,
org.springframework.ide.eclipse.boot.dash [962]
No resolution report for the bundle.
Martin mentioned looking for INSTALLED, but all I saw were ACTIVE, RESOLVED, STARTING, and <<LAZY>>. I ran diag on at least one bundle of each state, but got nothing any different than above (of course the names and IDs were different).
I was facing the similar issue with Spring Boot Dash view and using -clean option and restart STS worked for me.
Just faced the same issue upgrading to latest STS 3.8.3 based on Neon.2 (4.6.2). Starting with the -clean option did nothing for me, neither did uninstalling / reinstalling the Groovy Eclipse feature as discussed.
What resolved it for me was switching to a new clean workspace - the boot dashboard then started working again. Oddly, it also works if I now switch back to the old workspace. Before this, the module was showing as LAZY in the Host OSGi console, now it's ACTIVE:
966 ACTIVE org.springframework.ide.eclipse.boot.dash_3.8.3.201612191259-RELEASE
The problem was one of my Groovy Eclipse compiler plugins (it was 1.8, 1.9, 2.0, 2.1, or 2.2, not sure which). After uninstalling it the Boot Dashboard no longer has an error.
Since part of my question was wondering about how to get better insight into the problem (more than checking the error log, which was empty) I will not mark this answer as accepted.
I have been struggling with a very weird issue that has suddenly popped up on the latest version of Eclipse Classic (4.2.2).
Everytime I try creating or refactoring a class or subclass in any of my projects (all Java) in my Eclipse workspace I get an error at the very top of my class that says
A class file was not written. The project may be inconsistent, if so try refreshing this project and building it
Again, this happens when I create new classes. And even when I rename current classes, then undo the renaming, its totally fine, but changing a single character in the name causes this error to happen for that specific class.
I have Auto Build on, and I tried multiple times to clean and refresh every project as well as restart Eclipse entirely.
I have literally no idea how to even start figuring out how to fix this. The solutions i've found through search didn't help, so i'm hoping I might find any clues here.
I had the same problem and here's how I solved it in the end:
It turned out that the disc space on the drive where workspace resides was full.
Silly mistake but worth checking.
In my case, this was caused by the fact that the build output directories were owned by a different user, and Eclipse could not write into them.
I had the same issues, the following worked for me:
Right click eclipse then running "as an Administrator"
Click Project > Clean.
Clean your workspace by starting eclipse from the command line with the -clean argument :
eclipse -clean
See also How to run eclipse in clean mode? and what happens if we do so?
I solved this problem by running Eclipse as root.
I had the same issue on Mac OS X. I had a maven project.
Try running the following command on Terminal. This looks like an access issue.
sudo mvn clean
Provide password for admin user.
Then open Eclipse and refresh your project.
We are using Eclipse here too and have to handle a workspace with more than 200 plug-ins. Every now and then people have similar problems with their workspace and inconsistencies reported in a weird way by Eclipse.
What people here usually do is (next step only in case previous step didn't help):
- trying to ContextMenu->Team->Clean/Refresh the whole workspace
- creating a new workspace and check out all necessary files from the repository
- reinstalling Eclipse to a new directory
From my experience after using the Eclipse IDE on a daily basis for many years, it doesn't make very much sense to waste too much time with these issues, unless they aren't solved by one of the steps above. It takes too much time to struggle with these things, while starting from scratch is done in an hour or less (and usually fixes the issue).
If your Eclipse still behaves strangely it might make sense to go through your installed plug-ins. Not all external plug-ins follow the Eclipse guidelines and can seriously harm the performance and operational consistency of your Eclipse installation (E.g. Sonar Plug-in, Toad Plug-in, ...)
In my case this kind of error caused due to disk space got full and it got resolved by just freeing disk space where eclipse have been installed.
That is c/d/e drivers.
I come up with the same error, and in my case, this is because the permission of the project/bin directory is not recursively 775
I fixed it by:
Remove the project/bin directory: sudo rm -rf project/bin
Switch to Eclipse, rebuild the project: Project->Clean...
Then no errors.
Try to launch Eclipse as Administrator.
In my case such error was caused by a question mark in a quoted method name (I use geb+spock combination for automated testing).
So this method name will throw an error "Do you want something?"()
And this will not "Do you want something"()
It may not be the best response but to fix it, I've just delete the error marker.
Had the same issue. but cleaning the project and restart eclipse didn't help and disk space was not the issue. Solved the issue by copy the code to notepad(just to not lose it) and then delete the class, recreate it and paste the code back in again.
I solved it changed the owner of the project files. I changed from root(old owner) to user my current(user that i use with eclipse).
Just changed and saved java file to recompile the class. Then error disappeared.
I was try run
Project->Clean...
And Rebuild. My problem was resolved
For linux (Debia) and working on Spring boot project (maven):
$ sudo mvn clean
Then open Eclipse and File -> Refresh.
I had same issue, it is something similar but this post didn't help in my case. I have many inner classes which is causing the compiler to create class names with all inner class names together that is creating class name more than 255 character file limit on NTFS! read it in some other blog. I thought it will be helpful to post here.
Ex : classA$InnerClassB$......InncerClassZ.class in target folder it won't generate the class if it exceeds this limit. Try renaming your inner class name shortened. In my case i have to add InnerclassZ as its exceeding its not generating class and Eclipse complaining.
A class file was not written. The project may be inconsistent, if so try refreshing....
I shortened InnerClassZ to IClassZ fixed the issue.
I had the same issue and it got fixed by running eclipse in administrator mode
Eclipse Shortcut-->Right click-->More-->Run as Administrator
I've been throught that error once when I used wsdl2java to extract java classes from a wsdl, it turns out that all classes were created in the same "class", causing end classes with long names (error - File name too long). When I organized and rename some classes the error disappeared.
I had this issue. I did the following, it resolved.
Open Eclipse in Administrator mode; Right click on eclipse.exe "Run as administrator"
Clean all projects.
#Denny's answer put me on the right track, though in my case it was the target directory. I deleted it for some reason and something automatically recreated with owner root. Changing the directory owner was not enough as it contained files that were also owned by root. So make sure to really remove the complete content of the directory and to change the owner.
In my case current user didn't have access to this project dir
Before giving a try to the above solutions. Just cleaned the project and it worked.
I searched lot about this topics but can't find a proper solution.
I am using eclipse 3.6 Helios version with operating system fedora15. In my application I am using GWT2.4 for front end development.
Now while I work with debug mode and want to debug at some point at the same time eclipse hangs for 3-4 mins.It resumes after and again start to debug process.
I am using this eclipse from last 3 years with windows but not faced this issue.In fedora I am using it from last 4 months and this problems stated to occur from last one month.
I am not getting what is the issues with eclipse.
Please help me out.
Thanks in advance.
Is this something that happens with different projects/code, or is it the same code that causes freezes? I've had issues where threads have started in the background and caused problems.
You say "(...) hangs for 3-4 mins.It resumes after and again start to debug process.", what do you mean? Does it continue to debug and move to the next line, or is there a crash and it restarts?
How long has it been since you changed workspace? I've found this, rather than the Eclipse installation, to be an issue over time. Create a new workspace folder, export all your projects and preferences and start fresh.
You are using GWT 2.4 and I think you might be working with UI.xml too... There is a tag in each ui.xml at the top like
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
Which means eclipse is going to get that xhtml.ent file each time and there is a issue in GWT eclipse plugin have a look to below link
http://code.google.com/p/google-web-toolkit/issues/detail?id=5265
There is one comment which says
For me, removing
SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent"
and saving the document,
solves the problem..
maybe it is needed for something, so better you copy that locally somewhere, and link that.
Try it out and let me know.
I had experienced the exact same problem on a less-powerful notebook I had to use.
Try one of the following
Download the latest Eclipse version (It needs, just as helios, a lot of RAM and CPU because it's based on a new "architekture", in contrast to, for instance, galileo)
Make sure you are using the latest JDK and JRE
Download Eclipse Galileo, which does require pretty less resources and goes still very very fine with most projects!
It sounds like you are experiencing the features of the latest Eclipse arch. In the latest versions of Eclipse I have noticed that the more plugins and add-ons you have installed, the slower the environment runs. There are a lot of similar posts regarding performance on the new platform
I have removed all but the plugins I am using and never install anything not needed into the Eclipse environment.
I "may" have experience this. Not sure. Suddenly started working again. I was getting a hang every time I would try to debug an app, in the part of the code (inside GWT) that creates a "table" element. Could be that there is something that just takes a while and you just have to "wait it out" the when it happens. Go get a cup of coffee, type thing. anyway I HAD stepped deep into the GWT code, plenty so I'm convinced it IS a GWT issue of some kind.
I was thinking it was some infinite recursion possibly in the logging system (like logger code accidentally trying to log itself, and going into loop?). Also there's a 50/50 chance that it was simply clicking on 'run' instead of 'debug' made it start working again. So at least try that if you have problems. My gut instinct and 30yrs programming under my belt tells me it's logger related. I can rule out "slow computers" because I never had this happen until I got a new machien which is Dell XPS, Core i7, 8 GB ram, and massive disk. So I wouldn't blame hardware, or Eclipse bloat.
