• export JAVA_HOME=$GRAALVM_HOME

• git clone https://github.com/m3hdi652/java-ios.git && cd java-ios/HelloJava

• Using Maven:
  

  mvn client:build

• If the compilation is successful, HelloJava will appear in dist folder

• You can fake-sign the binary by using ldid:
  

  brew install ldid
ldid -S HelloJava

• You also can codesign the binary, if you have a free or paid developer account:
  

  Get your identity by security find-identity -p codesigning -v
  e.g:
  

  1. 2CD708151B6469F3D4B0F05F48338B81F1809C82 "Apple Development: example@example.com (5J8I29WF1D)"
