Supercoder fails with "java.lang.NoSuchMethodError"

[andrewfromtver]

Hello!

I packed it in Dockerfile and start with my vLLM backend

FROM ubuntu:22.04

RUN apt-get update && \
    apt-get install -y default-jdk && \
    rm -rf /var/lib/apt/lists/*

COPY ./supercoder /supercoder

WORKDIR /supercoder

ENV \
    SUPERCODER_BASE_URL=https://<my_vllm_backend_gateway>/v1 \
    SUPERCODER_MODEL=<my-model> \
    SUPERCODER_API_KEY=<my-token>

it throws error when I just type - "hello" also something strange going on with CLI

# ./bin/supercoder 
??????????????????????????????????????

vv0.1.4

Model: vllm-local
Type '/help' for available commands.

I tried to force wrong model usage and it showed me correct 404 error, but with correct model it fails

Hey, my bad, it seems like I put the wrong Java version in the readme file. What was the Java version in your docker container? the expected version should be Java 21 and above.

Hello, it seems that default java in 22.04 repos is 11, I build it with openjdk 21 and it looks working now

Hello! How can I assist you with your coding needs today?

Sure, I can help you write a simple Bash script. What would you like the script to do?
> iterate numbers from 1 to 5 and print each value

chat looks working but if I ask it to write script it seems to can not use tool calling

model on vLLM backend - qwen2.5 tools parser - qwen3_xml

[huytd]

the tool call handling code in this project is quite old, i haven't update it in a while, so it might not be compatible with newer models. unfortunately i don't have much time to maintain this yet.
