Error while signing a Photoshop extension

Jun 14, 2013 11:40 AM

I am trying (for the first time) to sign an extension that I have:


java -jar ucf.jar -package -storetype PKCS12 -keystore FILENAME.p12 -storepass PASSWORD -tsa Kwik2.zxp -C . .


However, I am getting the following error:


Packaging failed: Unable to create output file: Kwik2.zxp Unable to create output file: Kwik2.zxp

          at com.adobe.ucf.Packager.renameOutput(

          at com.adobe.ucf.UCFPackager.createPackage(

          at com.adobe.ucf.UCF.doPackage(

          at com.adobe.ucf.UCF.main(

          at java.lang.reflect.Method.invoke(

          at org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader.main(JarRsrcLoa


Any idea of what I may be missing?

Thanks a lot,

    In my experiences, the UCF tool will choke if the project's full path contains any spaces (even if you only provide relative paths to the tool, like you do). For example:


    "~/My Project/" (vs) "~/MyProject/"


    Why, I have no idea.
