NetBeans Janitor scan reports old versions - netbeans

I'm running NetBeans 12.6 on Wndows 10 (although this happened on previous versions). When I startup, after a pause, I get Notifications, saying "NetBeans 8.1 was last used 1,959 days ago".
If I click on it it offers to "Remove unused data and cache directories of NetBeans 8.1. Free up 154 MB of disk space."
If I say yes... nothing happens. And next time I run Janitor scan (from Tools>Options>Janitor, or on startup) the message is still there.
%APPDATA%..\Local\NetBeans\Cache does not contain an 8.1 directory, so it's not the cache.
Can anyone suggest what I need to do to make this work? and where are the 154MB of files it's referring to?
Thanks

I had the same problem with the Janitor notification. Except in my case I did find the cached folder it was referring to.
Kept getting the message to clean up xGB of old cache. Responded "Yes" and Janitor silently failed to clean up the old cache. Got annoyed, looked in the IDE log found the line
Cache Directory = "...."
Went to the cached directory, one level up, found and manually deleted the old cache folder. Problem solved.

Unable to start VSCode; suggestions for debugging?

I'm working on a disconnected network, so some options are a bit limited. Also, we have SAs who handle stuff like system updates (so, for instance, it is possible that there was a system update in there that I know nothing about).
However, I had 1.33.1, then 1.34.0, then 1.38 versions of VSCode working on my (Windows 10) machine. One day, for no apparent reason (I hadn't just installed something, for instance), 1.38 stopped working. It wouldn't even start up. Running 'Code --verbose' from the command line produced no output (the mouse cursor turned briefly to a spinner, but nothing even showed up in Task Manager, let alone something like a splash screen).
I did get an error message in the Application log, which included the lines (more or less; remember, no cut-n-paste possible):
Faulting Application Code.exe, version: 1.38.0
Faulting module ntdll.dll, version 10.0.16299.936
Exception code: 0xc0000374
Faulting Application path: c:\Program Files\Microsoft VS Code\Code.exe
Faulting module path: c:\Windows\System32\ntdll.dll
Re-installing VS Code (with or without system restart after uninstall) did nothing.
Removing all extensions (we have a bunch) did nothing
Installing 1.39.2 did nothing
The only good thing is that I can still run 1.34.0, if I reinstall that (did not try 1.33.1, and I don't have any in-between versions from 1.34 to 1.38 to try). So at least I'm not completely shut out.
I also tried deleting basically all of workspaceStorage, to no effect. Nor did renaming my storage.json.
The biggest weirdness, to me, is that the path to ntdll.dll is in System32, rather than in SysWOW64 (is there some way to force usage of the latter?). Second, why did 1.38.0 work just fine for a while, and then stop.
So, I'm curious if anyone else has seen this problem, and/or if anyone has any idea what else could be done to get more insight into what's causing this.
(edit: I plan to file bug for VSCode, but been waiting on confirmation email to finish creating my github acct for some time now. sigh)
I've had exactly the same problem twice. I'd been running the application since June 2019 and then in March of this year, Yep! Exact same problem as you encountered. A simple reinstall fixed that, but I've had the same problem again today and after some investigation, Windows 10 was telling me that I didn't have the right permissions to access the item (this is using the Owner's account!). Attempting to reinstall failed, with errors stating that the file / directory all ready existed and couldn't be overwritten or renamed. Attempting to un-install the application was only partially successful with the executable code.exe still remaining afterwards. The only way I managed fix it this time was to reinstall to a directory with a different name. Surprisingly though, all the existing workspaces, projects and extensions even were intact and the application opened where I had left off as though nothing had happened. This is a little worrying I have to say! But that's how I fixed it this time.

sql developer hangs on startup - what can I do?

At present I cannot run it (SQL Developer 4.1) because it hangs on "Restoring Editors" while starting. I suppose I've done it by exiting it before by killing sql developer process because it was hanged on fetching objects to Schema Browser so long...
Maybe I would clean some temporary files but can't find any.
Any ideas?
Deleting files from c:\Users\MY_USER\AppData\Roaming\SQL Developer\SQL History
and c:\Users\MY_USER\AppData\Roaming\SQL Developer\System...
Really helped me to resolve the connection issues
Basing on this thread https://community.oracle.com/thread/2564842 I've created own solution.
Extract installation of current version SQL Developer (4.1.0.17.29)
At "c:\Users\MY_USER\AppData\Roaming\SQL Developer\"
I've changed directory name system4.1.0.17.29 to system4.1.0.17.28.
After running newly extracted SQL Developer (4.1.0.17.29) I was prompted to let copy configuration from version 4.1.0.17.28 to 4.1.0.17.29 ;)
Everything works great now. I suppose that running the same (broken) installation after decreasing version could also help.
Remove folders c:\Users\USERNAME\AppData\Roaming\SQL Developer\system4.1.3.20.78\system_cache*. SQLDeveloper will recreate it after launching.
Just execute sqldeveloper as administrator. It works fine!
In my case the problem was because of windows compatibility issue. So I've selected my windows version and it's stop from randomly crash after startup
Our setup:
Windows 10
Sqldeveloper Versions <= 20.4.0
We observed this problem as well. Even worse while working over a VPN connection. I followed a couple of hints with more or less no effect.
To move
C:\Users\<USER>\AppData\Roaming\SQL Developer
to a local directory by adding this line
AddVMOption -Dide.user.dir=c:\temp\sqldev-conf
in the \sqldeveloper\bin\sqldeveloper.conf file gave us some improvement, but the “IndexPreferencesTask” still got stuck several times on startup.
After some more hours on unsuccessful research, we moved back from JDK 11 to JDK 8.
This solved 99% of the problem. The “IndexPreferencesTask” still hangs on startup but for less than a second.
Sounds to me like a problem with JDK 11.
In my case when i changed Tools --> Preferences --> Environment -> Look and Feel to Windows it is solved.
Delete the History files from C:\Users\User\AppData\Roaming\sqldeveloper
Restart the PC
In my case, the solution was kind of weird. After battling to resolve this for 2 days, no luck. Suddenly, on my mac, I searched for sql developer, not sqldeveloper. It popped up a sqldeveloper application (not sure how that is different from what I have been trying to open ), clicked it and boom, it opened. My guess is that there is a copy of that app on my system that I should have been opening rather than trying to open the reinstalled app. Note: I reinstalled the app after it started misbehaving though.
Operating System: Windows 10
Oracle Sqldeveloper Ver: 17.4.0
The problem has been noticed sometime when any network security
patch was installed on your machine. Looks like the patch impacts
your cached data under your user profile folder.
As above Lakh, rtbf and others answered. Removing below folders
will resolve the issue.
C:\Users\<userId>\AppData\Roaming\SQL Developer\SqlHistory
C:\Users\<userId>\AppData\Roaming\SQL Developer\system17.4.0.355.2349
If any one find more approriate reason please feel free to
disagree with my answer.

Eclipse randomly stopped starting

I've been using Eclipse a lot recently, and haven't had any problems with it. Last night, I was working on it perfectly fine. However, this morning, whenever I load it up, the program stops working half way the loading splash screen (before the actual workspace opens up). The information says "Loading Workbench" and just stays there forever. When I click on it multiple times, I get a message saying that Java(TM) Platform SE binary is not responding.
Google hasn't been a ton of help, and seems to just give a lot of responses about Minecraft. I'm slightly confused as to where I need to start looking, since nothing had changed since I successfully used it last. No updates to Java or Eclipse or anything else. Thanks for the help, and let me know if you need any more information!
I was actually able to fix it by just renaming my WorkSpace to WorkSpace1. Apparently it got corrupted somehow, and with the rename Eclipse was able to recreate a new one. Here's the link that helped me out:
http://spacetech.dk/eclipse-failed-java-was-started-but-returned-exit-code-805306369.html
Two things to check when you have problems with Eclipse:
First, always check the .log file, located in the .metadata directory (<workspace path>/.metadata/.log) of your workspace (not the Eclipse installation directory). Keep in mind that this is a hidden file under Linux or Mac OS. It usually contains the exception that is causing the crash. I usually delete any existing .log file before firing up Eclipse, just to make sure I am looking at the relevant log entries (the file will be recreated at startup).
If #1 does not help, you can try deleting the .metadata directory altogether. It will be recreated on startup (this is basically what you did by changing the workspace). In my experience with Eclipse, I noticed that some files can get corrupted inside .metadata, making Eclipse act weirdly. Keep in mind that this directory contains customizations you made in Eclipse and its plugins for the workspace and you might need to make them again.
Hope this helps.
Eclipse tends to be weird sometimes. If you move stuff around outside of the directories it was initially installed in, it usually won't load. I don't know if that's what you did, but your best bet is to back up your workspace, and reinstall eclipse. I'm sure that will do the trick.
Try a reinstall if possible or else, check the eclipse error log, which would be present at'/.metadata/.plugins/org.eclipse.ui.workbench/log'.
This will help you knowing the problem.

Eclipse getting too slow - workspace recreation helped

My Eclipse was getting slower and slower over time. Tips I found on the Internet did not help.
What I did is completely deleted my workspace, created new one and reimported all my projects into the new workspace and this really made the difference.
So my question is whether it's possible to perform this workspace clean-up without deleting and recreating workspace...
Maybe there is some cache in workspace which is getting big? Any ideas?
Thank you!
Eclipse keeps track of all changes in local history. That might introduce slowdown over time.
Local history is located at .metadata/.plugins/org.eclipse.core.resources/.history.
Not sure about newer versions of eclipse, but in 3.1 settings in
Preferences->General->Workspace->Local history
did not work for me. I had it set by default to 7 days but files were kept for 4 years. And I guess other people here had the same issue.
For me it helped to remove history files manually from
.metadata/.plugins/org.eclipse.core.resources/.history.
I use RAD 7.5 (which is based off of Eclipse 3.4). I found several of my projects had millions of history files, all older than 7 days, and mostly the same dummy MANIFEST.MF file (39 bytes).
I discovered this when I tried to delete an old project with Windows Explorer. After 12 hours, Windows Explorer reported that it had recycled 3.5 million files, and was still working.
I found the only way to remove the workspace was to open a Command Window, CD to
<project>\.metadata\.plugins\org.eclipse.core.resources\.history
then type
DEL *.* /s/q
Even this took the better part of an hour.
Try running eclipse from command prompt with
eclipse.exe -clean
More http://www.myeclipseide.com/PNphpBB2-viewtopic-t-10280.html
Sometimes due to Physical Memory issue it cant build the workspace.
So To remove Memory issues update #
eclipse.ini
file as below
-Xms512m
-Xmx1024m
-XX:MaxPermSize=1024m
--launcher.XXMaxPermSize 1024m
I just solve the problem by deleting all stuffs inside eclipse's directory OPTReplica. after that, re-stat eclipse, for me it helps.
Eclipse is programmed as a filebomb, and it causes a large variety of problem, evben on modern robust filesystem. Problem can goes from large waste of diskspace for nothing to preventing your OS to boot if your workspace is on your OS partition. Eclipse is programmed as a filebomb.
The cleanup mechanism in eclipse doesn't work, so the only viable option is to frequently cleanup your workspace by hand at regular interval, or to add your cleanup code to a sh file that does it before launching eclipse.
An other option will be to introduce the eclipse developpers to the fabulous world of databases that produce faster to run and easier to write code. Sadly a rhumor says that they will shot on sight everyone that pronounce the words "sqlite" or "jdbc", and will sacrifice virgind every sunday to the all-mighty-god-of-filebombs.

Missing disk drive in Eclipse Galileo

After extracting the Eclipse Galileo, it worked fine for a couple of days. But lately when ever I run it. It throws an exception/error :
Eclipse Galileo Error: there is no disk in the drive. please insert a disk into drive device harddisk2 dr2
Though I tried to remove it, and extract it again, however it still give me the same error!
Some plugin probably remembers a drive you once used it with. Try deleting workspace/.metadata !
Under windows, the directory name may be slightly different, and it may be hidden. Find it, kill it!
This is a brute-force solution. But since you were already willing to tear down and re-install Galileo, I see no further harm in it.
Read the exception literally - you don't have enough space on the hard-drive. Clean up some files and try again.
(by "cleanup some files" I mean - anywhere on the hard drive, not only in the workspace itself)
