I need the Eclipse Installation folder, it was requested from another program, but there is no such a folder. When I installed eclipse I did not get any folder out of the compressed file, I only get the program itself.
However, I copied the contents and it says " it's not the installation folder since it does not have "plugins" subfolder.
The error message
The new path for the plugins is
/Applications/Eclipse.app/Contents/Eclipse/plugins
The eclipse will be installed where you decided to put it not always under /Applications necessarily. The easiest way I think to find the installation folder is to run eclipse, go to Eclipse > About Eclipse. Click "Installation Details" at the bottom. The configuration tab in installation details should have the location of eclipse for launcher and startup config. Hope this helps!
In mac os you need to select the eclipse ini file not ecllipse.app

I just downloaded Eclipse Juno onto my machine. I extracted the files to an Eclipse subdirectory in "C:\Program Files". When I try to launch eclipse from here, it works great! But I don't want to have to navigate to this directory every time I want to launch eclipse. I tried just moving the executable to my Desktop, but then when I try to run it I get this message:
The eclipse executable launcher was unable to locate its companion library.
How do I let eclipse know where it's companion library is if I don't plan to have them in the same folder? Please be very specific.
Thanks!
You dont move the executable to your desktop because the executable needs to be in the same directory with other files where it was. get it back and then make a shortcut or link to it. you are free to make the shortcut or link where you want.
Well i had the same problem sometime back, and i figured out that since i've changed the location of my elcipse.exe , it has some how effected the "eclipse.ini " file
1.Path to -startup
D:\ < elcipse folder> elcipse:\ plugins\org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar \this is the start up jar file.
2.Path to shared lucher library
D:\ < elcipse folder> elcipse:\ org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20120522-1813 \this is the shared launcher library jar file.
just set the follwing two paths and ti will start up again like befor..
Happy coding..
This is a bug filed with Eclipse for Windows and Mac:
When attempting to launch Eclipse (double click on Eclipse.app), the launch fails. The only action is a dialog box with this message:' the eclipse executable launcher was unable to locate its companion shared library'. I found an online description of the problem and the workaround here:
Specifically, as per the instructions above:
I opened the Eclipse.app package, located eclipse.ini, edited it
searched the plugins folder for something matching org.eclipse.equinox.launcher.carbon.
copied the maching folder name (from plugins)
pasted it as the terminating portion of the path for --launcher.library
replaced the --launcher.library line with that path

Eclipse Neon, 2017:
I copied my old .p2 folder found in my home.
Ran eclipse again and it worked.
It used to be that you could just copy eclipse as a zip and it would work fine, but it seems some plugins now rely on the .p2 folder.
I feel really stupid by asking this question, but how can I install Json Editor Plugin in my Eclipse Helios? I looked at the Forum in sourceforge, but I can't install it neither through .zip or by adding a web site. And will I need to change the execution environment to Java 1.6?
Here is what I did to get the Json Editor Plugin to show up in the Install Dialog.
By doing a little Google-ing, I found this page which describes the steps to install JsonEditorPlugin on 3.4.
After you have followed the first 6 steps, make sure that Group items by category is un-ticked. After that, you can then choose Json Editor Plugin to be installed from the local Zip archive that you have downloaded from the net.
Edit: as a side note, you must not have the unzipped contents of the zip archive in the dropins/ folder, otherwise it will appear as if the plugin is already installed.
Simply dropping the zip contents into the dropins folder however did work also.
Note: You must right click your .json file and choose 'Open with' -> 'Json Editor'
You can install plugins by just unzipping them into the dropins folder.
It does not matter if the zip file contains the parent folders "plugins" and/or "eclipse".
I would recommend Java 1.6 as it brings a better performance and the plugin might require Java 1.6. On your desktop shortcut you use following execution arguments:
eclipse -vm <path to jre 1.6 installation folder>\bin\javaw
Download jsonedit-repository-0.9.7.zip (or whatever) and put it in a folder you like.
In Eclipse Help --> Install New Software
Add --> Archive button and select the zip file.
Name it and press OK
Press button Next and Follow master of installation.
Then after opening json file possibly needed right click mouse on the file --> open with --> JSON editor
I am behind an intranet that does not have access to the download sites. Assuming I have access to all of the correct zip and jar files. What are the step by step instructions to get Eclipse to the point where I can go to Windows -> Preferences and see the Google entry?
1) I don't have access to the http://code.google.com/eclipse/docs/getting_started.html site because I am on a closed network.
2) I tried using the dropins folder and when I re-open Eclipse and go to Windows->Preferences "Google" isn't listed.
Any ideas?
The official zip-file installation instructions are at http://code.google.com/eclipse/docs/install-from-zip.html
This uses the Eclipse dropins mechanism, which helps Eclipse to pick up the new plugins in a clean way, quote:
... the dropins folder can be used much like the plugins directory was used in the past. A subtle twist on old behavior here is that plug-ins and features added to the dropins folder are properly installed into the system rather than being forced in.
Note:
Make sure, that you extract the zip file into the correct destination. It can easily happen, that it gets extracted e.g. into some subdirectory - so please check twice. You should have the following structure:
eclipse (this is your Eclipse installation folder)
dropins
eclipse (this is the directory created by extracting the zip file)
features
com.google.*
plugins
com.google.*
features
(your already installed features)
plugins
(your already installed plugins)
...
Then (re-)start Eclipse.
Just install the plugin from here and you are set to go.
http://code.google.com/eclipse/docs/getting_started.html
If you get a correct zip file for plugin, you will see "plugins" and "features" as soon as you open the zip file.
If your eclipse is in a location "c:\eclipse", extract the zip file into "c:\eclipse". The files will go into the corresponding folders.
Drop them in the plugins folder
I have eclipse and I can test run java apps but I am not sure how to compile them. I read that I should type javac -version into my cmd.exe and see if it is recognized. It is not. So I went to sun's website and downloaded/installed JDK v6. Yet it still says 'javac' is an unrecognized command. What am I doing wrong?
Thanks!
UPDATE
OK after reading some replies it seems like what I am trying to do is create a .jar file that can be ran on another computer (with the runtime). However I am having trouble figuring out how to do that. This might be because I am using Flex Builder(eclipse), but I added the ability to create java projects as well.
Thanks
UPDATE
OK I do not want to make a JAR file, I am not trying to archive it...the whole point of making a program is to send it to users so they can use the program...THAT is what I am trying to do...why is this so hard?
To setup Eclipse to use the JDK you must follow these steps.
1.Download the JDK
First you have to download the JDK from Suns site. (Make sure you download one of them that has the JDK)
2.Install JDK
Install it and it will save some files to your hard drive.
On a Windows machine this could be in c:\program files\java\jdk(version number)
3.Eclipse Preferences
Go to the Eclipse Preferences -> Java -> Installed JREs
4.Add the JDK
Click Add JRE and you only need to located the Home Directory. Click Browse... and go to where the JDK is installed on your system. The other fields will be populated for you after you locate the home directory.
5.You're done
Click Okay. If you want that JDK to be the default then put a Check Mark next to it in the Installed JRE's list.
You don't need a separate compiler, eclipse already compiles the application for you. What you probably want to do is to create an "executable" JAR file, which you can do in eclipse by selecting File->Export->Runnable JAR file.
Note, however, that the resulting JAR file is not a "real" (i.e. Windows binary) executable - it still needs a JRE installed on the target computer. There isn't really a way to create windows binaries; that's not how Java works. On the upside, it will work without recompilation on a Linux or MacOS machine (if it has a JRE installed).
javac is located in the "bin" folder of your JDK installation. In order to run it you must either use full path or add this directory to your systems search path via the Control Panel.
If you installed to c:\program files\java\jdk1.6.0 your call will have to look like this:
c:\> "c:\program files\java\jdk1.6.0\bin\javac" -version
Umm, eclipse is an IDE, it compiles things as you go. You don't need javac.
If you have Eclipse installed and you can write new java apps from within it, your compilation should work already..
Eclipse automatically builds/compiles your system when you're saving new Java files. Just try to write a new simple Hello world app, printing something to the console (just type sysout and Ctrl+Space inside Eclipse)
Eclipse automatically compiles all project in the workspace. YOu can disable this option if you like under Project->Build Automatically.
A JAR file can function as an executable, when you export your project as a JAR file in Eclipse (as Michael Borgwardt pointed out) you can specify what's the executable class, that meaning which one has the entry point [aka public static void main(String[] args)]
If the user installed the JRE he/she can double-click it and the application would be executed.
EDIT: For a detailed explanation of how this works, see the "How do I create executable Java program?"

Since Eclipse 3.5 there seems to be no option to have drop a plugin jar ( not a feature ) in the Eclipse base directory and have it picked up at next startup.
Is there any possiblity to have plain plugins jars installed in Eclipse 3.5?
Since the advent of p2, you should be using the dropins directory instead.
To be completely clear create "plugins" under "/dropins"
and make sure to restart eclipse with the "-clean" option.
Simplest way - just put in the Eclipse plugins folder. You can start Eclipse with the -clean option to make sure Eclipse cleans its' plugins cache and sees the new plugin.
In general, it is far more recommended to install plugins using proper update sites.
For Eclipse Mars (I've just verified that) you to do this (assuming that C:\eclipseMarsEE is root folder of your Eclipse):
Add plugins folder to C:\eclipseMarsEE\dropins so that it looks like:
C:\eclipseMarsEE\dropins\plugins
Then add plugin you want to install into that folder:
C:\eclipseMarsEE\dropins\plugins\someplugin.jar
Start Eclipse with clean option.
If you are using shortcut on desktop then just right click on Eclipse
icon > Properties and in Target
field add: -clean like this: C:\eclipseMarsEE\eclipse.exe -clean
Start Eclipse and verify that your plugin works.
Remove -clean option from Target field.
go to Help -> Install New Software... -> Add -> Archive.... Done.
in Eclipse 4.4.1
copy jar in "C:\eclipse\plugins"
edit file "C:\eclipse\configuration\org.eclipse.equinox.simpleconfigurator\bundles.info"
add jar info.
example:
com.soft4soft.resort.jdt,2.4.4,file:plugins\com.soft4soft.resort.jdt_2.4.4.jar,4,false
restart Eclipse.
This is how you can go about it:
Close Eclipse
Download a jar plugin (let's assume its testNG.jar)
Copy testNG.jar to a certain folder (say C:\Project\resources\plugins)
In your Eclipse installation folder, there is a folder named dropins (could be C:\eclipse\dropins), create a .link file in that folder, (like plugins.link)
Open this file with any text editor and enter this one line:
path=C:/Project/resources/plugins
Save the file and start Eclipse.
And you are good to go!
Please do not forget to change your backward slashes in your plugins folder path to forward slashes on step 5. I used to forget and it would take my time unnecessarily.
