[ant-javacard] targetsdk 3.0.5 leads to CAPs with version 2.1

[faibian90]

Hello,

I try to create a CAP file for my JCOP 4.5 JavaCard. When using the targetSdk value 3.0.5, a CAP file with version 2.1 is generated. CAP file version 2.1 is very old and was lastly used in Javacard 2.1.1. (2.2 was introduced in Javacard 2.2)
I am getting an error status word (6985) on the first load command, when trying to load this CAP file. Although the JCVM should be downwards compatible, I assume that my JCOP 4.5 card does not like this CAP file version and returns the error. But I am just assuming here...

What do I have to do, to get the ant-javacard-task to generate CAP files with version 2.2 when using the targetSdk value 3.0.5?
Following you can find my build.xml and parts of my verbose output.
I can see in the header component of the CAP file, and the load command, that the version of the CAP file is 2.1 and that the packacke_name in the header component is missing (introduced with 2.2)

Thank you

build.xml:

I could already find out, that the CAP could not be loaded onto my JCOP 4.5 card, because I was importing the GP API in version 1.8. I used the version 1.6 and it worked.
I could bring ant-javacard to create cap files with version 2.2 by activating the debug component.

The cap file version is handled by the converter. You are probably chasing the wrong thing here.
