FlashBuilderC v4.7 returns NoClassDefFoundError: com/adobe/flexbuilder/codemodel/common/CMFactory

[Tr0n]

We are building FlashBuilder projects as part of continuous integration via ANT scripts. It looks something like this:

    <target name="main" description="Build all flex projects">

      <fb.exportReleaseBuild project="ProjectA" destdir="somedir" />

    </target>

And a .bat file that runs FlashBuilderC with standard parameters:

--launcher.suppressErrors -noSplash -application org.eclipse.ant.core.antRunner -data %WORKSPACE% -file "buildFlexContents.xml" main

So far this has worked great with FlashBuilder 4 and 4.6, but when we updated to 4.7, the following started to happen (parts of the .log file):

I have tried recreating the workspace, and changing -vm JDK paths to try with 1.7 to no avail.

Funny part about this is, that it works with FlashBuilder.exe (inside the GUI), but not with FlashBuilderC from the commmand line.

Any ideas why it can't find this class?

[Tr0n]

No one with the same problem? Can you build with FlashBuilderC flex projects using ANT?

Hi,

I believe I'm having same issue.

did you manage to resolve it?

here is the error I'm receiving:

I'm also investigating it with Adobe at the moment, so far without much success.

Thanks,

We are also experiencing this exact same issue! Been working on this for two full days, resetting the workspace from scratch twice without success!

Hi,

I'm still investigating this with Adobe Support.

By the way, did you also overlay Air SDK version by any chance? (We did overlay to version 14).

On what OS does it happen? For us it happens on Win2008 R2 Standard 64bit.

Thanks,

Erez.

[Mowday]

Hi Erez,

Nope haven't overlayed anything on the build environment.
It's on Windows 7 Pro 64bit.

Hi Carl,

Good to know we are not alone ..

Not sure it's relevant, but we do have both FB 4.6 and 4.7 on those build machines in which the issue occur.

It builds fine in GUI, but gives this nasty error when running from command line.

Is it same for you?

btw, I'm fairly new to Flash environment, so I'm not sure what type of project is it (I do know it works well in the GUI).

I understand from Dev team the the project type is ActionScript Mobile Project.

Is it same for you either?

What else can we possibly check?

thanks,

Erez.

Hi,

I was instructed by Adobe Support to open a bug, which I did:

Bug#3801869 - FlashBuilder 4.7 command line fails due to "Exception in com.adobe.flexbuilder.codemod...

Please review and see if you have more info to add about this bug.

Thanks,

Erez.

We actually fixed the problem by removing one of the projects in FB. The project works fine in GUI, but not from command line.
As it's not needed for what we are doing we just removed it.

If you have several projects, try removing them one by one and readding until it fails. That's what we did

[Guest]

Hi Mowday,

So you actually got it to work from command line, right?

We have one main project, which has referenced libraries to 3 other SWC files (which were also imported to the project).

When I remove any of them from the GUI, the project fails to build in 4.7 GUI.

Any idea how to debug it?

thanks,

Erez.

I was experiencing the same problem and found a solution that works for me.

The build process seems to leave behind a few .snap files in the .metadata directory within the FlashBuilder workspace root.   I used the following powershell command to delete the snap files before I attempted the command-line build:

Remove-Item -include *.snap $FLASH_WORKSPACE\.metadata\ -Recurse

$FLASH_WORKSPACE is the variable that points to my workspace.

[romann]

Thanks mrcrowl! You solution just fixed my build process on OS X.

--

Here is how to do the same in Bash:

find "$FLASH_WORKSPACE/.metadata/" -name '*.snap' -print0 | xargs -0 rm -rf

[romann]

Just had the same issue again, googled it and found my own answer here.

Thanks romann​ for the useful answer!
