A Gradle plugin for building JavaCard applets.
This plugin is a wrapper on ant-javacard and Global Platform Pro, it is inspired by gradle-javacard
- build JavaCard applets (with the same capabilities as ant-javacard)
- install cap files
- list applets
- write quick testing scripts used to send apdu in a configurable way
- expose
GpExectask type that enables usage of Global Platform Pro tool inside Gradle - include jcardsim 3.0.4 and JUnit 4.12 test dependency (clear distinction between JavaCard SDK & jcardsim SDK)
- ability to specify key for delete/install/list tasks
- possibility to add dependency between modules (exp & jar imported automatically)

The path to JavaCard SDK can be specified through :
- use
jc.homeproperties inlocal.propertiesfile located in your project root (in the same way as Android projects) :- in project root :
echo "jc.home=$PWD/oracle_javacard_sdks/jc222_kit" >> local.properties
- in project root :
- using
jckitattribute (see ant-javacard) JC_HOMEglobal environment variable, for instance using :export JC_HOME="$PWD/sdks/jck222_kit"
| task name | description |
|---|---|
| buildJavaCard | build JavaCard cap files |
| installJavaCard | delete existing aid & install all JavaCard cap files (gp --delete XXXX --install file.cap) |
| listJavaCard | list applets (gp -l) |
It's possible to create custom tasks that will send series of custom apdu :
scripts {
script {
name 'select'
apdu '00:A4:04:00:0A:01:02:03:04:05:06:07:08:09:01:00'
}
script {
name 'hello'
apdu '00:40:00:00:00'
}
task {
name 'sendHello'
scripts 'select', 'hello'
}
}The above will create task sendHello that will select applet ID 01:02:03:04:05:06:07:08:09:01 and send the apdu 00:40:00:00:00.
The order of the scripts's apdu in task.scripts is respected.
00:A4:04:00:0A:01:02:03:04:05:06:07:08:09:01:00 or '00A404000A0102030405060708090100' are valid apdu.
You can build custom tasks that launch Global Platform Pro tool :
task displayHelp(type: fr.bmartel.javacard.gp.GpExec) {
description = 'display Global Platform pro help'
group = 'help'
args '-h'

}Note1 : the remote dependency will automatically download the jar (the jar file must include the exp file)

(*) If you specify at least one dependency, jcardsim & junit won't be automatically added so you will need to add them manually if you need them for example :
test {
dependencies {
compile 'junit:junit:4.12'
compile 'com.licel:jcardsim:3.0.4'
}
