Create `gradle.properties` as described below\n1. Run `./gradlew convertJavacard -i`\n\n## Configure Java Card home\n\n`gradle.properties` can include something like:\n\n    com.fidesmo.gradle.javacard.home=PATH_HERE/oracle_javacard_sdks/jc304_kit/\n\nor you could use an environment variable (name?).\n\n## Install and Test\n\n1. If you have a Status Keycard, it has a **non-default development key**.\n   \n   In that case: `export CARD_KEY=c212e073ff8b4bbfaff4de8ab655221f`\n\n1. Install to card with `./gradlew install -i`\n1. Ping applet with `./gradlew ping -i`\n\nYou can also run unit tests, after cloning this repo in the parent directory:\n\n    (cd .. \u0026\u0026 git clone https://github.com/status-im/jcardsim.git jcardsim-status)\n    ./gradlew test -i\n\n## Utilities\n\nRecommend building https://github.com/martinpaljak/GlobalPlatformPro and using\nthe gp.jar command.  For example `gp -list` (with `-key $CARD_KEY` if using Status Keycard)\nwill list the installed applets.  This library is also used for our install and uninstall\ntargets.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdevrandom%2Fjavacard-helloworld","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdevrandom%2Fjavacard-helloworld","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdevrandom%2Fjavacard-helloworld/lists"}
