How can i use this suggested intelliJ command to disable double buffering? - intellij-idea

I use intelliJ 12 - despite requests from ages ago, it still runs really slowly on a remote connection.
One of the suggested settings is to use
RepaintManager.currentManager(null).setDoubleBufferingEnabled(false);
I have no idea what that means, but I am keen to try it out - can someone let me know how I can execute this command on my intelliJ? So that it will work smoother, i mean?

Original issue has a comment that links to this answer with the link to plug-in jar. Download the jar, Install from disk in Setting | Plugins.

IntelliJ-How to solve this problem about Git is not installed : Cannot invoke(class=Listener, method=beforeTaskStart,topic=ProgressManagerListener)

Thank you for come in to my ask :)
I have a problem when I first installed intelliJ and tried to set path to Git executable.
intelliJ setting screenshot
**I tried to solve this problem like this
remove git and retry to install git for homebrew
retry to install git from intelliJ "Download and install"
set another path like this "/usr/bin/git" (it has same result too)
**
but it didn't help so I search in google but there is no about
***"Cannot invoke(class=Listener, method=beforeTaskStart,topic=ProgressManagerListener)"
This is my first question so maybe my writing is a little bit poor
I would appreciate it if you could take a good look :) Thank you
The Cannot invoke class error looks like some unhandled exception in the logic that runs git commands. There might be several reasons for that, one of which is actually a corrupted installation.
Please try doing a clean install by downloading dmg from the web site, and make sure to select the one corresponding your system Intel or Apple Silicon.
If this does not help, IDE logs might have more details on the exception, and an optimal way would be to report the error and share logs with IntelliJ Support

Intellij 2018.2 stops working and exits on MacOs. What might be a problem?

As an daily IntelliJ user you usually concentrate on the projects you are working on and IntelliJ is just a tool. You are not willing to dig into tool's problem itself. But this is what is forced on you by default after IntelliJ installation on MacOS and opening relatively big project(most of the projects nowadays are huge and have thousands of files and use numbers of IntelliJ 3rd party plugins).
Here is a minimal list of actions. IntelliJ must have set MORE RAM to be used by default.
Read: https://intellij-support.jetbrains.com/hc/en-us/articles/207241085-Locating-IDE-log-files .
From IntelliJ open Help / Show log in Finder and open idea.log file with Console.app; In Console.app press "Reload" and "Now" buttons to track "live" what IntelliJ is doing.
If in logs of IntelliJ you find that some of the plugins exit with fatal error, you just uninstall those plugins. For me the one that failed to the moment of this answer was "BashSupport" as example.
Start Terminal.app ; Run command: open -a TextEdit /Applications/IntelliJ\ IDEA.app/Contents/bin/idea.vmoptions ; Change options in idea.vmoptions file to:
-Xms1024m
-Xmx2048m ; Read https://www.jetbrains.com/help/idea/tuning-the-ide.html to see how you can tune IntelliJ for your project. This step is handy when your IntelliJ app doesn't start at all and you want to change properties in a global way.
From IntelliJ open Help / Edit Custom Properties.... Here you can set same properties that will override global and will work only for current OS user.
Also there is also a possibility of underlying OS to do it voodoo magic so the IntelliJ won't work as it should like here - https://intellij-support.jetbrains.com/hc/en-us/community/posts/360000398280-IDEA-Ultimate-2018-2-Unable-to-save-settings-Unable-to-create-file-Windows-10
Make sure your project build output for *.class files is set. Read: https://intellij-support.jetbrains.com/hc/en-us/community/posts/360000000584-Build-does-nothing . In my case when IntelliJ started project build it terminated without warnings shortly after.
Finally in my case none of 6 steps above solved the issue so I found this read: https://intellij-support.jetbrains.com/hc/en-us/community/posts/115000532044-IntelliJ-cannot-build-projects . Basically try reinstall IntelliJ from original distribution again.
I know that you must read https://www.jetbrains.com/help/idea every time you install a new version of IntelliJ, but why not to add some consistency into configuration process of the main java process that runs IntelliJ itself? You can ask how much ram to use during installation of IntelliJ and explain why it is so. Then Help digging won't be necessary in the first place for devs who fed up with changing those default settings that will be always more than 700MB. I think for most devs out there it is at least 10x of that. I bet what makes most devs mad about this is not the fact that you need to do some options changing, but where those options are depending on OS plus the fact that you simply forget why IntelliJ app just exits while you are doing a debugging of your own app. I bet this problem makes us mad since first java based IDEs appeared. User-friendly is the key here and explicit reminders within the app itself would help.

Intellij IDEA 13 - Can't open Project Structure dialog anymore

as already described in title, i'm not able to open the project structure dialog window in intellij anymore.
neither the shortcut (Ctrl+alt+shift+s) nor the menu element under File -> Project Structure nor the little button in the upper right corner do work.
Clarification: Menu element :
This "bug" occured suddenly as I wrote a web (vaadin/maven) project and tried to set up glassfish, where i often had to switch to the project structure dialog.
Since the first occurence i wasn't able to fix it by restarting intellij or switching projects.
This also happened on my laptop running the same intellij and windows version (Ultimate 13.0.1 Build: 133.331 on Windows 7 x64)
i appreciate any help!
This also happened to me, but removing new plugins etc didn't help.
Nor did nuking my project and rebuilding it from scratch.
In the end I deleted all caches, restarted Intellij and at last I could access the project settings again! By the way, I'm using Intellij 11.1 - mainly because I can't get 13 to start up, but that's another story
Your log shows that it is a bug in IntelliJ IDEA - they are trying to create file passing null pathname. Try to delete project files and reopen project from scratch (maybe you've lost some file) - if it won't help then you should create an issue here: http://youtrack.jetbrains.com/ - You can even copy-paste text from your question and attach stacktrace
I had the same issue...upon further inspection in the log dump...I noticed the following:
ERROR - llij.ide.plugins.PluginManager - com.intellij.openapi.fileChooser.FileChooserDescriptor.setTitle(Ljava/lang/String;)V
java.lang.NoSuchMethodError: com.intellij.openapi.fileChooser.FileChooserDescriptor.setTitle(Ljava/lang/String;)V
at com.jetbrains.python.sdk.PythonSdkType.getHomeChooserDescriptor(PythonSdkType.java:247)
Disabled the latest Python Plugin and restarted and everything is working normal again.
I remembered I had recently update my python plugin and am not using it presently so I was able to disable it without issue.
Hope this helps someone else.
This also happened to me. The comment above helped. I had just added some plugins. Disabled them and it started working again. Not sure exactly which one because I disabled all 4 -- Bean Validation Support, Bitbucket, Jelastic Cloud Platform Integration, and Quick Notes.
For me it has been resolved by switching off FindBugs plugin and restart IDEA. So Project Structure is available for me now.
One of the plugins might be causing it. To disable a plugin, go here:
You'll know for sure if a plugin is bad if you see this Exclamation picture:
Clicking on it will bring up a pop-up. To disable the plugin, click on this:
For me it got resolved just by restarting the intelliJ IDEA. I'm using intelliJ IDEA Ultimate 2018.1 edition.

couldnt recognise pom.xml file

i am build forge as build tool. it is executing maven mvn commands fine ,but it couldnt recognizing the maven project pom.xml to run the build.so i tried to execute the same pom.xml through the command window and that is working fine could any one can help me how to solve the issue
i am using maven 2.09 version and build forge 7.1
is there any compatibility issues with maven if so what are they
thanks Dagg
I'm not sure you'll find more Build Forge knowledge here on SO (but I may be wrong) than on the forum where you posted the same question :) Build Forge doesn't seem to be very popular actually (and its forums not very active). That said, according to this message, it should be possible to kick off a maven project but, according to other messages from the same thread, the support seems limited and you are "on your own".
In your case, my guess is that maven is not started in the right "working directory" (or it should be able to find the pom). But this is just a guess, I don't have any BF knowledge (lucky me).
To be honest, you should consider talking to your IBM commercial guy or to IBM support or, if this is an option, just using something else than BF unless it's really providing value. Maybe your organization will thank you after all.

Setting up an Erlang development environment

I'm interested in looking at Erlang and want to follow the path of least resistance in getting up and running.
At present, I'm planning on installing Erlang R12B-3 and Erlide (Eclipse plugin). This is largely a Google-result-based decision. Initially this will be on a Windows XP system, though I am likely to reproduce the environment on Ubuntu shortly after.
Is there a significantly better choice? Even if it is tied to one platform.
Please share your experiences.
I highly recommend the Erlang mode shipped with the standard Erlang distribution. I've put together a "works out of the box" Emacs configuration which includes:
Syntax highlighting & context-sensitive indentation
Dynamic compilation with on-the-fly error highlighting
Integrated Erlang shell
And more....
You can browse my GitHub repo here:
http://github.com/kevsmith/hl-emacs
I've only done a small bit of coding in Erlang but I found the most useful method was just to write the code in a text editor and have a terminal open ready to build my code as I need to (this was in Linux, but a similar idea would work in Windows, I'm sure).
Your question didn't mention it, but if you're looking for a good book on Erlang, try this one by O'Reilly.
You could also try NetBeans there's a very nice Erlang module available: ErlyBird
Install Erlang: sudo aptitude install erlang
Install a recent JDK: sudo aptitute install sun-java6-jdk
Download and install (the smallest) NetBeans edition (e.g. the PHP one): www.netbeans.org/downloads
download the erlang module ErlyBird: sourceforge.net/projects/erlybird
manually install the modules via NetBeans
ErlyBird features:
syntax checking
syntax highlighting
auto-completion
pretty formatter
occurrences mark
brace matching
indentation
code folding
function navigator
go to declaration
project management
Erlang shell console
I'm using Erlang in a few production systems personally as well at the office. For client side testing, documentation and development I use a MacBook Pro as the OS/platform and TextMate with the Erlang bundle as an editor.
For sever side development and deployment we use RHEL 4.x/5.x in production and for editing I use VIM. Personally, I've got 4 machines (slices on slicehost.com) running Debian using Erlang for a few websites and jobs.
I try to go with the smallest 'engineering environment possible', usually the one with the fewest dependencies from apt or yum.
To add to the Emacs suggestions, I would also recommend that you look at the advantages of distel when running the Emacs erlang-mode.
I've seen answers suggesting TextMate here, so I wanted to add another good Mac OSX tool:
ErlangXCode plugin to XCode.
I've been using this since I started with Erlang and really do like it.
The download link on his blog is broken, here's the real download:
http://github.com/JonGretar/erlangxcode/tree/master
You could also try a virtual server on demand service like this one from CohesiveFT
Select the components you want (e.g. erlangrb12 + yaws + MySQL + erlyweb) and it will build a vm image for you to download or to put onto ec2.
Rolling you own locally is quite straightforward too if you follow the instructions in the pragmatic programmers book Programming Erlang
Just a quick note:
The Erlang "compiling" process described in Ciaran's post (described for Ubuntu 6.10 btw) can be easily skipped using apt command in any Debian based distro:
apt-get install erlang
Do not forget to install these packages if you see it fit:
erlang-doc-html - Erlang HTML document pages
erlang-examples - Some application examples
erlang-manpages - Erlang MAN pages
erlang-mode - editing mode for Emacs
Good Luck!
I like Justin's suggestion, but I'll add to it: this solution is great for learning a language. If you don't rely on something like code-completion, then it forces you to learn the language better. (If you are working with something with a huge API, like Java or Cocoa, then you'll want the code completion, however!)
It's also language-agnostic, and in the case of an interpreted language, particularly one that has an interactive interpreter, you'll probably spend just as much time in the shell/interpreter typing in commands. Even in a large-ish python project, I still work in an editor and 4 or 5 terminal windows.
So, the trick is more about getting an editor which works for you. I'm not about to suggest one, as that's heading towards evangelism!
I just use Scite. Type something and press f5 to see the results.
Just wrote a guide on this on my blog, heres the abridged version:
Part 1: Download what needs to be downloaded.
Download and install the Erlang run-time.
Download and install TextPad.
Download a .syn file for Erlang and place it in the system folder of TextPad. For me, this folder was C:\Program Files\TextPad 5\system. I'm not quite sure who did this syn file (the site is in another language), but they did a good enough job.
Part 2: Set up syntax highlighting.
Open up TextPad. Ensure no files are opened. Go to the 'Configure' menu, and select 'Preferences'. In the preferences window, click 'Document Classes'. There should be a list of currently recognized languages. Click the 'New' button (it is right under the list of languages), and type 'Erlang'. Click apply.
Click the '+' button next to 'Document Classes'. This should expand the list, and Erlang should now be on it. Click Erlang. You should see a list of file extensions associated with Erlang, click 'New', and type '*.erl'.
Now click the '+' button next to 'Erlang' on the left. This should expand a list of several more menus. Click on 'Syntax'. Click the drop down menu and select erlang.syn. If erlang.syn is not there, then the .syn file was not properly placed.
Feel free to edit some other syntax options to customize TextPad to your liking.
Part 3: Compiling from TextPad.
Note: as of 12/05/08 there are severe problems with compiling in textpad. The Erlang shell somehow ignores new compilation when it is done in text pad. This is only useful for checking for errors, when you want to actually run the code, compile it in the Erlang Shell.
In the preferences menu again, click 'tools' on the left.
Click the 'Add' button and select 'Program...'. Navigate to the erl5.6.5\erts-5.6.5\bin\ folder and select erlc.exe. Select and single click the new entry in the list to rename it. Click 'Apply'.
Now click the '+' button next to Tools on the left. Select erlc, or whatever you have named the new tool (I named mine 'Compile Erlang'). The parameters field needs to read '$File', and the initial folder field should read '$FileDir'.
I have had good success with Erlide.
If you use Vim I recommend you Vimerl (http://github.com/jimenezrick/vimerl):
Features
Syntax highlighting
Code indenting
Code folding
Code omni completion
Syntax checking with quickfix support
Code skeletons for the OTP behaviours
Uses configuration from Rebar
Pathogen compatible (http://github.com/tpope/vim-pathogen)
From what i've tried (and are still up to do), a good addition to an erlang dev. environment would be a virtual machine running ubuntu/yaws/erlang. Perhaps Erlyweb (erlang/yaws framework) would be nice checking out too.
Ciaran's posts (this would be the first of his "series") about his erlang install is nice, as he details the steps in setting up the server (and other stuff like xmpp with jabberlang).
Since you're switching to Ubuntu eventually anyways, I highly recommend using erlang-mode for emacs (which comes bundled with the Erlang distribution). It is officially what all the core developers use and what many other developers use because of the many features it offers you.
Installing the Erlang distribution itself should be simple :)
