Netbeans automatically cloning my jar based packages with their empty 'name equivalents'

I'm new at java programming so i just wanted to try something with ssh understand how it works and so i downloaded a java library which is mentioned in this Stack Overflow answer
. After a lot of failed attempts on importing this library into netbeans. I decided to simply put the files into my src folder. But Netbeans ide duplicating packages in the jar file with their 'name equivalent' empty packages and this prevents me to reach the classes in the packages because the IDE and the Code completion automatically sees the empty packs.I've search the network couldn't find anything about this problem.I 'm ready to share any log files if there are any of them .Here is my screenshot about this situation.

OS : Linux Mint Rosa
IDE : Netbeans 8.1 Linux version
Edit : I Already looked these topics
How to use .jar files in NetBeans? : At first i've tried this and in this solution netbeans not duplicating any empty packs but when i start to type somethin' like that import sshj.foo.*; Auto Complete can't find anything and also if i try to write the whole path to a specific class which is in an specific pack IDE gave me an error the pack that you're looking for is not exist.Secondly I've tried this
and got the same issue at first try.I can see the packs,classes and other stuff but still can't reach them in a random class which is imported project.
How can I include external jar on my Netbeans project : I've tried this and also this ran perfectly without errors as they said but when i try to reach classes still got the same problem so nothing changed.
How to add a JAR in NetBeans :
In this topic all of the replies explained types of libraries.That's not even related to my problem
How to use classes from .jar files? : I've tried to do explained in this reply also and I've transfered my jar file into a compiled .class extension file and this didn't solve my issue too.

I've just solved that problem with downloading part of the libraries from here.
All libraries need to contain three kind of jars ;
1 . Compiled files containing jar (with extension .class)
2 . Source files containing jar (with extension .java)
3 . Javadoc files containing jar (optional)
Open a project find libraries folder on ide right click and choose Add JAR/Folder specify the directory that contains the compiled files.After importing library hit right click over it and choose edit then specify the source files and javadoc files directories you are ready to roll.

BlueJ Importing custom class library

Ok the deal is, I've made a small class library (*.Jar file) to help make a more visually organized code and to help with some common tasks.
Before you tell me to go to: Tools > Preferences > Libraries.
I have done that, over and over and over again.. I also tried to manually add it to: C:\Program Files\BlueJ\lib\userlib\"jar file here"
And yes, i did restart BlueJ to load the newly added libraries.
No matter what i seem to try it won't let me import it to my project using the import command, but without it, it just won't compile.
I know i can just add the classes manually, but as the class library slowly grow, so does the effort of adding all the classes in that library.
In advance, thanks for your help and consideration.

If adding your jar file in the Preferences > Libraries tab doesn't work, you can try adding the jar to the "userlib" directory at <bluej-dir>/lib/userlib (where <bluej-dir> is the folder where BlueJ was installed).
A third option you can try is adding your jar file directly to a project by creating a +libs directory inside your project directory and copying the jar to that directory. This has the drawback that you have to manually copy the jar to each project +libs subfolder that needs your library. On the plus side, it allows you to distribute your project (library jars included) just by zipping up the root project directory.

On Windows I create directory named "+libs" on my blueJ project directory,
then add .jar to that directory, and restart blueJ ,
that´s help me, and import after that work fine

Despite the post's oldness for who stumble upon i can say with the newest version of BlueJ (actually 4.1.3) in an old Ubuntu distro(Lucid Lynx aka 10.04LTS) all work as intended per default without any hack

Eclipse SVN always includes auto generated bin dir and classes no matter what I do

I am using Eclipse Juno with Subversive plugin.
I have a java project set to compile automatically which creates a lot of bin dirs
No matter what pattern i put in window-> preferences->->team->ignored resources, eventually i see the bin dir and all of it's sub dirs in the team synchronizing perspective as new uncommitted files.
I have tried the following syntax:
*/bin,**/bin, */bin/, */bin/*
No luck.
Also, I have noticed that sometimes if I close eclipse and start it again, the ignored files disappear from the team synchronizing perspective as required, but still, some bin dirs are still present. This whole thing is very inconsistent.
Any idea ?
I have forgot to mention that I am using two worksets, one is the subset of the other, this add buggyness to the whole process appearently

Try the "Subversive SVN JDT Ingnore Extensions". It is located on the Juno Update Site, under "Collaboration". Its description says:
The feature is useful for Java development because it allows to automatically interpret output folders as ignored resources.
Seems like exactly what you want. Also, it should work independently of the name of your output folders which is an advantage if you use Maven for example (in that case, your output folders will probably be called target and not bin).

I gave up and switched to Subclipse. Now everything seems to be working fine, or at least less buggy.

Eclipse edit java files and run under original folder

Although this seems an easy thing I'm not able to find the answer for it.
What I'd like to achieve is simple. I have a folder with java source files and I want to edit them using eclipse within a new project. But at the time of running the application I don't want eclipse to use the workspace project folder as "root", instead it should use the folder with the java source files.
The effect should be like opening the source files with a text editor directly and changing them, but instead this should be done through an eclipse project but still use the original folder to run the application.
I just want to have all the advantages that come from editing source files within an eclipse project instead of using something like notepad++.
I tried linking the source files and changing the relative path to the source directory but it doesn't work. When running the application it needs xml files which exist in the directory but because it's running "from" the eclipse project folder it doesn't find them.

I'm not sure I really understand what you want to do, but sounds like you want to set the run configuration's working directory: Open 'Run Configurations', choose the class containing your main method (or create a new run configuration for that class first if it's not yet there), then specify the Working Directory on tab 'Arguments'.

I do same with all my projects. What you need to do is :
Create workspace directory on different location than your source code.
Import your source code in your workspace directory. Here don't copy source to your workspace
EDIT
In Eclipse
Go to File->Switch Workspace->Other-> Type "new directory workspace" path, click OK. Eclipse will restart.
Go to File->Import->General-> Existing Projects into Workspace-> Next-> Select Root directory
Eclipse will list your project, select it.
Start editing and saving files.

Thought this does not directly answer your question, as an alternative to using Eclipse IDE for Java files try using Padclipse which is a text editor based on Eclipse.
Padclipse is a light weight text editor based on Eclipse. The basic
product is composed of Eclipse RCP plus Text Editor, Compare and
Search facilities and their dependencies. A few additional third party
plug-ins are included as well.
Check it out here
Also, the default JDK on my system was a 64 bit because of which starting up padclipse failed. Create a padclipse.ini in the folder where you unzipped it in and put in the following contents :
-showsplash
-launcher
padclipse.exe
-name
Padclipse
--launcher.library
plugins\org.eclipse.equinox.launcher.win32.win32.x86_1.0.0.v20070523\eclipse_1017a.dll
-startup
plugins\org.eclipse.equinox.launcher_1.0.0.v20070606.jar
-vm
C:\dev\jdk\1.5\1.5.0_21\jre\bin\server\jvm.dll
Change -vm argument to point to the java.exe or jvm.dll of a 32 bit jdk.

Where to tweak an Eclipse to change the default settings used when creating a new Workspace?

We use Eclipse with projects in CVS. It has proven to be the simplest to create a new workspace when having to deal with another branch or application, and then use Team -> Import project set to get all the needed projects from CVS.
Unfortunately, I then have to do the following each and every time:
Change text font to Consolas 11 pt
Disable spell checking in text editors
Run everything in the background
plus some more of the same.
I'd like to change the standard values once and for all in the Eclipse distribution files after having unzipped the distribution (Windows). Where are these defaults located inside Eclipse?
EDIT: For now we just have a preference file which must be read in. An extra step, but works...
EDIT 2014: I've ended up creating a workspace with the settings I want, and then creating a new copy everytime I need a new one. Also handles Maven Central information etc. Accepted the oldest answer saying essentially this.

You can export your settings from a workspace and import them into any other (this basically does what VonC's answer says, but with some measure of error checking).
To do so, in the source workspace select File->Export...->General->Preferences, then select Export All and enter a file to export to, then Finish.
You can then import the preferences into any workspace by doing File->Import...->General->Preferences, browse to the preferences file and hitting Finish.

I have created a clean workspace with all settings i want to have. This workspace i have copied into a save folder i will never delete ;)
When i want to create a workspace for a new project, i copy the confugured workspace and thats it.
I have than configured the svn repository path, code format (you also can import preferences in eclipse for this), view configuration and so on.

Try checking:
<workspace>\.metadata\.plugins\org.eclipse.core.runtime\.settings
Some .prefs files could be interesting to copy from one workspace to the next.
(like org.eclipse.team.cvs.ui.prefs which contains any non-default value for CVS settings)
I want to fix the defaults inside Eclipse so the workspace is created with the defaults I want every time.
Hard core solution:
Change the .options file within <eclipse-SDK-3.5-win32>\eclipse\plugins\org.eclipse.team.cvs.core_3.3.200.I20090430-0408.jar (that is the name I have for eclipse3.5)
That is the file with the default values, at least for CVS.

Here's what I do:
Start up Eclipse
Without importing or starting any projects, edit the workspace and make all the config changes you want
Open up the workspace in windows explorer and create a copy of the folder.
Then, any time you wish to use it, copy this folder to your new workspace folder location - you may need to create the new workspace folder first (and definitely call it something different.)
This is what I do anyway. Yes, it's very dirty but it does get what I want pretty quickly!

When importing preferences (Rich Seller's approach above), especially those that were created by someone else, make sure you backup your Eclipse environment first. That's easy, since it's portable - just copy it to a temporary location.
I've totally hosed my Eclipse environment importing preferences in the past, and importing my own preferences, which I exported just prior to importing, did not fix my issues.

Fix the defaults inside Eclipse so the workspace is created with the defaults, If you want every time suggestions, then
Go to eclipse extract path -eclipse\configuration\.settings -> Edit -org.eclipse.ui.ide ->
Change value to true: SHOW_WORKSPACE_SELECTION_DIALOG=true
Similarly in this file you can directly change other default settings.

I find a way to do that:
open <eclipse>\plugins\org.eclipse.cpp.package.cpp_1.4.2.201210131-1456\plugin_customization.ini
and add
folding
org.eclipse.cdt.ui/editor_folding_enabled=true
org.eclipse.cdt.ui/editor_folding_preprocessor_enabled=true
then new project will enable folding by default.
So
You need to know where your prefer locate, in my case, folding is under org.eclipse.cdt.ui, you can try on an project then check <workspace>\.metadata\.plugins\org.eclipse.core.runtime\.settings to find it
"org.eclipse.cpp.package.cpp_1.4.2.201210131-1456" should be variable depends on what version you use. whatever it's, you should find "plugin_customization.ini "
