I have a pretty good idea of the reasons nb-javac exists - but I don't use Compile on Save, and the presence of nb-javac suppresses the ability to use preview features.
It is of course, easy to uninstall. But what I cannot figure is once uninstalled how to avoid getting the warning message telling me to install it on every startup. Anyone figured this?
The rest of the IDE seems to work fine with it not present. It's just an annoyance always seeing that message.

I use emacs org-mode heavily, but don't usually use emacs otherwise. I am still using emacs 25.3 but also have 26.3 installed. This evening, after a Windows Update (likely cause of the problem?), when I restarted emacs (runemacs) under 25.3 I received the following error message.
error: Required feature ‘ht’ was not provided
I have also tried running it under emacs 26.3 and receive a slightly more helpful error message "c:etc. etc. /AppData/Roaming/.emacs.d/elpa/ht-20190924.704/ht.elc failed to provide feature ‘ht’"
I have not changed or updated any of the packages in several weeks. So, it is unlikely to be a change in org-mode or emacs.
I have experimented around with a variety of different approaches but without any luck. Among other things I restored the elpa files and my customization files from a back-up of a couple of days ago without getting a different results.
package-list-package with emacs 25.3 works with the error message, and I can upgrade the packages (2) that can be upgraded. However that also makes no difference to the error message I receive when I restart emacs. This does imply that ht.elc is working since, without it, you can't install packages since the new package needs to have its hash code checked. If I delete the ht package and try to update packages without it, updates fail on the hash code check.
package-list-package with emacs 26.3 is a whole other problem which might be why I'm not using it. TLS connections fail, and it can't connect to melpa, orgmode.org, etc.
In any case, I can't load my customization files and can't use org-mode at this point. Anyone have any ideas, questions or suggestions?
Thanks in advance.
This is a solution, without being an answer.
Using package-list-packages, and looking at the details for the ht package, it showed an "alternative" version being available from melpa; same release number. So, I chose to install it and a refreshed list of packages then showed that I had the same version installed twice.
I then closed emacs and restarted it. It started with a similar error message, but this time referring to the dash package. Repeated the duplicate install process as described above.
I again closed emacs and restarted it, and now it loads and runs correctly.
I had tried previously to just delete the ht package from the elpa directory, but doing that and attempting to install a fresh package resulted in a shower of errors. I don't remember all of them but at least one of them was that emacs was unable to read the package signature.
So, problem solved, but I still have no idea why it occurred in the first place, since it had been weeks since I had updated any packages, nor why the restore of the directories from several days ago didn't solve the problem.
And before anyone yells at me about moving to the current emacs, I have now installed the missing dependencies and am running on 26.3.
so I have a problem. I accidentally deleted Eclipse folder and I wanted to install Eclipse again. But when I run installation it freezes the moment I run it, and I have to exit it...please help me
It would be informative to observe and mention any system error during installation attempt. By the way, I hope you are installing the right version for your operating system and more so, you have the recommended system requirement like RAM size, processor speed. I suggest:
Restart your system.
Use a system tool like Advanced System Care (free) and scan your system.
Well, I don't know what happened but I tried to install it 2 times, it freezed and didn't work. When I tried third time it worked. :D So yeah. Magic.
I had the same issue. Everytime I tried to install Eclipse, the installer froze at some point. Turned out it was a problem with the firewall. I tried the installation over a hotspot from my phone and it worked.
Might not be the problem for you, but I thought I leave this here, as I was trying for quite a while and almost gave up.
I'm trying to get EclipseFP (Haskell support, but the original coder stopped maintaining it last month) working on my iMac but everything seems to fail constantly. I've been debugging this for hours now and like most other Haskell stuff there isn't much decent support out there regarding the installation of such tools. I haven't even written a single line of Haskell code yet (apart from some playing around in GHC/GHCI which surprisingly did work)!
I've tried so many things already, different libraries, different solutions, different versions etc. But it seems that everything that has to do with haskell support is just one big clutter of confusion for me and nothing seems to point me in an apparent direction which bothers me since I am an experienced programmer and dealing with command line interfaces, tools and dependencies isn't unknown to me on all sort of platforms for years now.
Even the most relevant topics on StackOverflow or other knowledgebases just won't cut it regarding this topic and I'm starting to feel like dropping the entire Haskell language and just use something which does play nice with the system without such troubles since it is already such a pain in the ass to get the most basic development tools to work, let alone the coding itself...
The things I got:
Mac OSX Yosmite
GHC
GHCI
Cabal (repository)
Eclipse Luna
I've installed EclipseFP using the install instructions which worked out all great. At this point I thought it would just all work without any problems as the plugin installs just fine...
Well, that was not the case of course. I've restarted Eclipse as it requested after installing new plugins. Here is where the trouble begun..
In the following steps I would have to open the Haskell Perspective in Eclipse. Well... guess what.. there was none! After strolling the web I found out that it might have compatibility issues with the old JDK 1.6 which was installed by default on MacOSX. No worries.. I've downloaded Java JDK 1.8, set it up in Eclipse, restarted it. And there the item "Haskell perpective" showed up in the list.
After clicking that, and thinking my troubles were over (and I could finally start coding!) nothing happend! I've searched around for a while and found the Eclipse error console which until this day gives me nothing more than:
An error occurred while automatically activating bundle net.sf.eclipsefp.haskell.ui (459).
org.eclipse.e4.core.di.InjectionException: java.lang.RuntimeException: org.eclipse.core.runtime.CoreException: Plug-in net.sf.eclipsefp.haskell.ui was unable to load class net.sf.eclipsefp.haskell.ui.HaskellPerspective.
Of course I have tried solving this issue and came across some dependencies which needed to be installed using cabal (BuildWrapper, Scion-Browser and some other essentials). After doing so I still have the same problem and I have no idea where to look for. The only information I can really find are topics which are more than 3/4 years old which share 0 relevance to my exact problem.
I could paste the Java stacktrace here as well which came with the error message, but it doesn't show much useful information anyway other than just basic crashing.
I hope someone can help me because I would really like to start coding now for a change instead of wasting hours on getting my basic development framework/IDE set up.
Long story short; I'd like to code some Haskell in Eclipse but the development tools just won't install and/or work properly without any notable errors or directions to look for.
(I've read this question, but that answer doesn't solve my problem, so don't mark this one as duplicate)
I have a fresh installation of Eclipse (Eclipse for PHP Developers / Helios Release / Build id: 20100617-1415 on Windows 7 x86) I can't install any plugin or addition. Neither from official plugins repository, nor from user-provided URLs.
Installation, even of tiny plugins takes "years" (starting at 10-20 minutes, ending on over an hour) though I'm on quite very fast Internet connection (around 2 MB/s), which is strange itself. And it always ends up with the same error message:
An error occurred while collecting items to be installed
session context was:(profile=epp.package.php, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).
Comparison method violates its general contract!
Comparison method violates its general contract!
Error message is always the same, always mentioning epp.package.php, no matter, what plugin I'm trying to install. So I assume, that this is Eclipse-related, not plugin-related problem.
I did some reasearch on StackExchange (many similar topics but clearly programming question, related to errors in Java or Javascript code) and in the Internet in genereal. The only thing directly related to Eclipse, that I found was this forum topic saying about some know bug in Eclipse. Though this bug is marked as resolved fixed, I tried to adapt one of proposed quick solutions of starting Eclipse with:
eclipse.exe -Djava.util.Arrays.useLegacyMergeSort=true
(other, similar sources are unclear, whether there should be a space between -D and java.* or not)
But this has brought no effect. Again, installing even small plugin even from official repository takes very, very wrong and upon progress bar reaching around 20% (after about 20-30 minutes) entire installation process ends up with above error.
I have newest available stable versions of Eclipse for PHP and JRE.
I've read this question, but it brought me no closer to the solution. I saw no difference, when starting Eclipse with java.util.Arrays.useLegacyMergeSort=true switch and I wasn't able to update core Eclipse to newest version, because this process also failed with the same error.
And this does not explains, why installing anything takes so incredibly long on fairly fast connection?
Is downgrading to JRE 6 the only option I have?
The -Djava.util.Arrays.useLegacyMergeSort=true must come after the -vmargs switch, as that changes the command line from specifying Eclipse launch arguments to arguments to the JVM, which any -D would be.
Use this solution or upgrade to at least Indigo SR2.
We want to add command-line support to Netbeans, as in being able to run any program (using the full path of the current file as the argument) directly from the IDE. The same way you can do it already on Notepad++ with the Run tool.
Apparently there is a plugin called VCS Generic Command-Line Support that offers this functionality, but when we try to install it we get this error message:
Some plugins require Master Filesystem to be installed
The plugin Master Filesystem is
requested in version >= 1.1 but only
2.15.2 was found.
Any ideas?
EDIT
I Did some googling as you got me interested pretty much everything i found was in refernce to NetBeans 5.x or below... Im thinking maybe its not compatible with 6 - but thats just a guess.
Looks like a version incompatability with "Master Filesystem". Maybe they are checking the version improperly or perhaps they really mean it needs to be 1.x >= 1.1. Do you have the newest version of VCS Plugin?
As an aside if Im going to have to chek this out... ive been dying for external tool support like in my beloved Eclipse :-)
