 Description  « Hide
When using ANT <fdt.launch.application> as always, I found out today (and previously with other 4.6 betas) that I get an exception during compilation:

at com.powerflasher.fdt.core.launch.debug.DebugSessionManager.getDebuggerFor(
at com.powerflasher.fdt.core.launch.debug.DebugSessionManager.launchSessionFor(
at com.powerflasher.fdt.core.launch.debug.DebugSessionManager.launchSessionAndKillOld(
at com.powerflasher.fdt.core.launch.AbstractTargetStarter.runListenerStarters(
at com.powerflasher.fdt.core.internal.launch.compile.concrete.CompilerProcess$

java.vendor=Apple Inc.
BootLoader constants: OS=macosx, ARCH=x86, WS=cocoa, NL=en_US
Framework arguments: -product com.powerflasher.fdt.product.product -keyring /Users/joeyvandijk/.eclipse_keyring -showlocation
Command-line arguments: -os macosx -ws cocoa -arch x86 -product com.powerflasher.fdt.product.product -keyring /Users/joeyvandijk/.eclipse_keyring -showlocation

I am only calling FDT ANT tasks like they are working with Flex SDK 4.5(.1) with all AIR versions (2.6 / 2.7 / 3.0), but apparantly something is crashing. It occurs when building for AIR3.0 and FP11.0 + AIR3.1 with FP11.1.

Its a big project so I cannot share it, but because it previously worked with different AIR versions (and with or without AIR3.1 / FP11.1 changed definitions) but not any more with this new Flex SDK. I saw also that the SDK from ( Adobe Flex version) is default now an AIR setup (possibly due to flash plugin choices).

Any tips on sharing more debug information would be helpful, while I only grasped it from the Error Log in Eclipse.

Hope you can discover whats happening, while this error I also got using the beta/prerelease versions of Flex SDK 4.6, so I presume it has to do something with the way FDT uses the Flex SDK compiler.

Thank you guys for your reports!

We were able to resolve the issue and a fix will be released via the FDT 5 update site quite soon.


Luckily there is a easy workaround that will resolve the issue for you as well:

  • Go to your flex 4.6 SDK
  • edit the content of flex-sdk-description.xml from:
<?xml version="1.0"?>
<name>Flex 4.6.0</name>


<?xml version="1.0"?>
<name>Flex 4.5.0</name>

Thanks Philipp, this workarounf fix my error on FDT 5 Max ( 64bit Mac Os X 10.7 )

Error for Air 3.1 on Desktop for iPhone and Android, but no error in Device publication.

But questions:

  • The compiled file stay in Flex 4.6 ?
  • Any update soon to fix this issue ?

Thanks !

Germain, an Happy FDT 5 max owner ( and happy for years )

Any news on this?
Workaround did not work for me with AIR 3.1 and now still not working with AIR 3.2.

I can confirm the above workaround mentioned by Philipp works nicely.

I'm using the latest Version of FDT 5 but this issue still exists. Anyway the workaround works. When will we get FDT 5.5?

Stay tuned this week for a beta.

I can confirm this works seamlessly now in 5.5 Beta
