Can I install the standalone version of FDT identically on more than one system?

To install FDT to more than one system, there is the option to create a "Property File" of the configuration details. In that case, you would have to start your first installation of FDT with the following command:

installername -f 'path to properties file'

and the following with:

installername -f 'properties file.'

FDT Installation fails (Unsupported major.minor version)

FDT needs at least Java 1.7 to run properly. Test your install of java here.

I'm on Windows and the Plugin repository isn't working

This is a temporary issue that will be fixed soon. Until then the current workaround is:

Paste the .jar files into the plugin directory of FDT, restart FDT and reset the perspective

haXe Plugin: download

Pflection: download

My Startup (Splash) Screen Is The Default Eclipse Screen

When FDT is installed as a plugin, we could overwrite the default splash screen but we've decided not to. It's a best practice among the Eclipse community to not override the standalone Eclipse install in this way. This is because the user may have another Eclipse based product installed. For example, if you've downloaded the standalone version of Aptana and then install FDT as a plugin - we'd be overriding the Aptana screen with our own.

How can I Install FDT 5 As A Plugin?

When FDT 5 was released, installation as a plugin was not supported. We recommend the stand alone version be used if possible.

If it works out best for you to use the plugin version, we will soon provide a plugin option for everyone.

On First Run I only see only two menus (top bar)-"Edit" and "Window" (Linux)

Try going to Window>Customize Perspective and click 'Ok'. This may provide the proper menus scheme.

Configuring FDT

How can install the Flex SDKs?

When upgrading to or installing FDT 4.5, you'll need to make sure you have the appropriate Adobe Flex SDKs installed. Below is a video that will walk you through downloading and adding the SDKs to FDT.

We also have a general SDK Management tutorial available as well. Check that out if you'd like to learn more about using SDKs with FDT.


Can I Import or Export FDT Color Themes

FDT doesn't have official support for importing and exporting color themes. It can be done, but may require extra steps. The reason for this that color themes in Eclipse are saved within the workspace preferences - along with other preferences such as keystrokes. For now, the best is to Google 'Eclipse Color Themes'.

Here is a good link to start

How Do I Customize Launching FDT

Check out this page to learn about Customizing How Projects Are Launched

Can I reset the default preference file in FDT

Eclipse would re-create the configuration folder with all the configuration files by deleting the configuration folder and forcing Eclipse to start up using the default settings. However, the FDTs settings are partly stored in the workspace as well as in FDTs directory. When deleting these configurations there is also a chance that the workspace will get messed up. Even if it works without problems the user will have to set up each project he had in his workspace once again. It is recommend to make a fresh installation of FDT instead, that way you are on the save side.

Using FDT

Getting Started

We have devoted a section on our wiki to getting you running with FDT quickly. Check it out.

Is ActionScript 2 still supported?

While FDT4 has no longer support for AS2. You have the option to buy FDT 3.5 with AS2 support as a special bundle with FDT4 for US$99.

How can I reset the default Project Templates and Project Templates?

To reset the Project Types delete the folder projectTypes within the user-wide FDT configuration folder (/Users/username/Library/Application Support/FDT, C:\Users\username\FDT) and restart FDT.

To reset the Project Templates delete the folder projectTemplates within the user-wide FDT configuration folder and restart the New Project Wizard.

Where has the FDT Parser Preferences moved to?

Due to the new SDK Management we removed the parser settings and replaced the functionality with the FDT Compiler Preferences.

How can I define path variables for linked resources?

The preferences are now within the general workspace preferences (General - Workspace - Linked Resources). You can also click on the link within the FDT Welcome Screen to open them.

Why are there some wizards missing within Flash Explorer's New menu?

Please reset the FDT Perspective to refresh all entries. (Window - Reset Perspective...)

My profiler isn't working with FDT 4?

Please reset the FDT Perspective to refresh all entries. (Window - Reset Perspective...)

I'm having trouble using the debugger on Linux

Please see this blog post for more info about Adobe's SDK support for Linux and how to work with it.

I changed the project's SDK but nothing changed in my .as3_classpath file

We moved the classpath in FDT 4 Milestone 2.

How do I get rid of the FDT 3 Compatibility folder? I only want to use FDT 4!

If you don't need downward compatibility anymore you can just delete any of its files. The folder is only existing if your project contains any legacy file.

How can I use trace() with AS3?

The Flex SDK which is included in the FDT stand alone installation has to be installed. Furthermore you need the Flash Debug Player to start your application. Please make sure that you're really using the DEBUG PLAYER. If you want to check which version of the Flash Player is installed on your system visit the Adobe Version test. If everything is installed correctly open your main class and start your application with "Debug As... --> FDT AS3 Application" (instead of "Run As..."). Two consoles in eclipse will open one for the compiler and one for the debugger. The console for the debugger shows the output of your traces.

I'm trying to import the fl package and I get an error...

Use "compc.exe" from the FlexSDK to create an SWC library out of the following folder:

<Adobe Flash CS3/4>\en\Configuration\Component Source\ActionScript 3.0\User Interface

Use this SWC as linked library within your project afterwards. Alternativly you can use the folder directly as "linked library".

How can I improve FDT's performance?

To improve the FDT performance you can try the following suggestions:

  • Remove unused SDKs from FDT
  • Close unused project
  • Uncheck "build automatically"
  • Raise the memory value in eclipse.ini adding the following two lines:
    • Xms128m
    • Xmx768m

Note: On a machine with only 1 gb of ram, lowering the value to 512mb will improve the performance

We found also a good tip on Quora

Things Are Slow or I'm Getting Odd Errors

Try cleaning your workspace / projects and resetting the compiler.

I'm getting this ERROR 403...

Please check the settings of your firewall.

  1. Preferences...
  2. Select Install/Update
  3. Select "Enable http proxy connection"
  4. Insert proxy address and port
  5. try again

When I Debug or Profile My Application, The Perspective Doesn't Change

Check out your Perspectives settings:
Prespective control.png
There's an option to: Open associated perspective when an application suspends. Also take note that when you have FDT SWF Application selected within the Application Types/Launchers section you have the appropriate settings under Modes/Perspectives.

How Do I Get FDT to Ignore Specific Files or Folders Such as .SVN

Within the Flash Explorer, there is a filter option for what types of files and folders are visible.

Ignore svn.png

Why is the flex.swc included in AS3 projects

There are various reasons for this, but most notably it has to do with the use of the [Embed] metadata tag. With the use of such a tag the Flex compiler will pull in additional classes, from the mx package, to handle the asset embed.


The use of code like the snippet above will result in the addition of classes such as BitmapAsset. The tricky part is that if the classes are omitted, the compiler will not throw a compile time error. Rather it will throw a runtime error.

Check this video tutorial:

How Can I Profile a SWF I Create Via Flash Authoring

The best way of doing this is to use one of FDT's Ant tasks.

Check this video tutorial:

I can't Debug Android Mobile Projects

Make sure you have the

<uses-permission android:name="android.permission.INTERNET" />

node in your Android permissions.

WIth FDT 5, this is not activated by default but will be in 5.1. See this JIRA ticket for more info.

How Do I Use The New Mobile Components In Flex 4.5 (Hero)?

  1. You'll first need to download the new Hero SDK.
  2. Add the Hero SDK using FDT's SDK Management
  3. Add mobilecomponents.swc to your classpath

Also see this post by Marvin Blase on using using Hero and FDT.

Can't package AIR

If you're having problems packaging your AIR applications, this error may be caused by a misconfiguration of your air release launcher. In order to package an .air file you will have to add at least the .SWF and the application discriptor to package successful. The following screenshot shows how to do so: http://screencast.com/t/T3AzRzJKn8Z
