Build

./gradlew build

Update library

1. Download distributions from release page with a shell script - src/main/shell/download_distributions.sh
2. Copy helics.jar to the libs folder of the project. The jar file might be copied from macOS, win32, win64 distributions (from java folder) or might be built with docker image together with libhelicsJava.so.
3. Build libhelicsJava.so for unix and make sure libhelicsJava.so is copied to src/main/shell before going to the next step, otherwise unix.zip will be incomplete.
4. Zip all libraries and put them to resources with a shell script - src/main/shell/pack_archives.sh

Building libhelicsJava.so for Ubuntu

• Run helics builder docker image with interactive bash docker run -v C:\temp\helics:/helics -it helics/helics:helics-builder /bin/bash <- change mounting folder if needed
• apt-get update && apt-get install openjdk-8-jdk vim -y
• cd /helics && git clone https://github.com/GMLC-TDC/HELICS && cd HELICS && git checkout v3.3.0 && mkdir build && cd build <- change to your tag
• vim ../interfaces/java/addLoadLibraryCommand.cmake Comment out the loading of library System.loadLibrary on lines https://github.com/GMLC-TDC/HELICS/blob/main/interfaces/java/addLoadLibraryCommand.cmake#L21-L26, we load the library on our own here https://github.com/LBNL-UCB-STI/helics-wrapper/blob/master/src/main/java/com.github.beam/HelicsLoader.java#L26-L37
• cmake -DHELICS_BUILD_JAVA_INTERFACE=ON .. && make -j8
• Copy libhelicsJava.so (lib/libhelicsJava.so) to src/main/shell and helics.jar (interfaces/java/jarproject/buildjar/helics.jar) to libs
