By far the best solution is the OSX Eclipse Launcher presented in <a href="http://torkild.resheim.no/2012/08/opening-multiple-eclipse-instances-on.html" rel="noreferrer">http://torkild.resheim.no/2012/08/opening-multiple-eclipse-instances-on.html</a> It can be downloaded in the Marketplace <a href="http://marketplace.eclipse.org/content/osx-eclipse-launcher#.UGWfRRjCaHk" rel="noreferrer">http://marketplace.eclipse.org/content/osx-eclipse-launcher#.UGWfRRjCaHk</a> 

I use it everyday and like it very much! To demonstrate the simplicity of usage just take a look at the following image:

blocks|key|1749557|text|为此，您需要导航到Eclipse.app目录并使用以下命令：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1749558|open+-n+Eclipse.app|code-block|syntax|javascript|1749559|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

To make this you need to navigate to the Eclipse.app directory and use the following command:

<pre><code>open -n Eclipse.app

blocks|key|1747962|text|实际上，一个更好的解决方案是将Eclipse.app复制到例如Eclipse2.app，你将在Dock中有两个Eclipse图标，在Spotlight中也有Eclipse2图标。根据需要重复此步骤。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1747963|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Actually a much better (GUI) solution is to copy the Eclipse.app to e.g. Eclipse2.app and you'll have two Eclipse icons in Dock as well as Eclipse2 in Spotlight. Repeat as necessary.

Instead of copying Eclipse.app around, create an automator that runs the shell script above.

Run automator, create Application.

choose Utilities->Run shell script, and add in the above script (need full path to eclipse)

Then you can drag this to your Dock as a normal app.

Repeat for other workspaces.

You can even simply change the icon - <a href="https://discussions.apple.com/message/699288?messageID=699288&#699288" rel="nofollow">https://discussions.apple.com/message/699288?messageID=699288&#699288</a>

blocks|key|1749467|text|另一种方法是只复制"Eclipse.app“文件，而不是复制整个eclipse目录的多个副本。右键单击"Eclipse.app“文件，然后单击复制选项以创建副本。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1749468|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

One another way is just to duplicate only the "Eclipse.app" file instead of making multiple copies of entire eclipse directory. Right-Click on the "Eclipse.app" file and click the duplicate option to create a duplicate.

If you're like me, you probably have terminal running most of the time as well. 
You could just create an alias in /Users//.bash_profile like this
alias eclipse='open -n path_to_eclipse.app'

then all you have to do is just open the terminal and type eclipse.

You can create an AppleScript file to open Eclipse with a given workspace. You can even save the AppleScript file as an Application, which is equivalent to creating an alias with arguments in Windows OS.

Open Script Editor and type the following:

<pre><code>do shell script "open '/path/to/your/Eclipse/installation' -n --args -data /path/to/your/workspace"
</code></pre>

For instance:

<pre><code>do shell script "open '/Applications/Eclipse.app' -n --args -data /MyWorkspaces/Personal" 
</code></pre>

Press the Run button to check it's working.

This script can be saved as such, but I prefer to save it as an Application. That way I can customize the icon by copying the *.icns icon from the original Eclipse.app bundle to the script application bundle.

To open an App folder, use the "see contents" contextual menu option. It should look like this:

<a href="https://i.stack.imgur.com/SPeZu.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/SPeZu.png" alt="contents of script app"></a>

Where "main.scpt" is the AppleScript file and "applet.icns" is the icon from the original Eclipse bundle.

I found this solution a while back, can't remember where but it still seems to work well for me.

Create a copy of Eclipse.app for each workspace you want to work in (for this example ProjectB.app), then open ProjectB.app/Contents/MacOS/eclipse.ini and add these two lines at the beginning of the file:

<pre><code>-data
/Users/eric/Workspaces/projectb
</code></pre>

... substituting where your workspace is located. When you launch ProjectB.app it will automatically start with that workspace instead of prompting for a location, and you should be able to run it at the same time as other Eclipse instances with no problem.

This opens a new window and you can then open another project in it. You can use this as a workaround hopefully. 

It actually allows you to work in same workspace.

How can I open multiple Eclipse workspaces at the same time on the Mac?

On other platforms, I can just launch extra Eclipse instances, but the Mac will not let me open the same application twice. Is there a better way than keeping two copies of Eclipse?

Open multiple Eclipse workspaces on the Mac

如何在Mac上同时打开多个Eclipse工作区？在其他平台上，我只能启动额外的Eclipse实例，但Mac不允许我打开同一个应用程序两次。有比保留两个Eclipse副本更好的方法吗？
