BytecodeAnalyser is a tool made for use in the CommandAPI's GitHub Actions to compare the bytecode to make sure that the commandapi-bukkit-nms-common module is compatible with all versions the CommandAPI supports.
While intended for use in the CommandAPI's GitHub Actions build, you can also run it locally.
For that, clone the repository first:
git clone https://github.com/CommandAPI/BytecodeAnalyser.git
To compile the BytecodeAnalyser, cd into the directory you cloned it to and run:
./gradlew jar
The compiled jar will be in build/libs/.
Because this depends on compiled modules of the CommandAPI, also clone the CommandAPI:
git clone https://github.com/CommandAPI/CommandAPI.git
To obtain the required structure that the BytecodeAnalyser expects, cd into the directory you cloned the CommandAPI to and run:
./compileNMSCommon.sh
To run the BytecodeAnalyser, copy the jar you got from compiling the BytecodeAnalyser into the commandapi-platforms/commandapi-bukkit/commandapi-bukkit-nms/commandapi-bukkit-nms-common/target folder that you have after running the compileNMSCommon.sh script.
After that, just run:
java -jar BytecodeAnalyser*.jar
