### Search before asking - [x] I had searched in the [issues](https://github.com/apache/incubator-devlake/issues?q=is%3Aissue) and found no similar issues. ### What happened I am writing a plugin for devlake to do some customized metrics calculation, I begin by writing a minimal plugin, I write PluginEntry in plugin.go and PluginMeta etc in impl/impl.go, and the plugin can success compile and generate .so file, after I make a image with official devlake and copy .so under /app/bin/plugins, devlake will try to load it during the startup, but it always show "plugin already loaded" error message like: ``` devlake-1 | panic: attached stack trace devlake-1 | -- stack trace: devlake-1 | | github.com/apache/incubator-devlake/core/runner.LoadGoPlugins devlake-1 | | /app/core/runner/loader.go:88 devlake-1 | | github.com/apache/incubator-devlake/core/runner.LoadPlugins devlake-1 | | /app/core/runner/loader.go:38 devlake-1 | | github.com/apache/incubator-devlake/server/services.Init devlake-1 | | /app/server/services/init.go:123 devlake-1 | | github.com/apache/incubator-devlake/server/api.Init devlake-1 | | /app/server/api/api.go:58 devlake-1 | | github.com/apache/incubator-devlake/server/api.CreateAndRunApiServer devlake-1 | | /app/server/api/api.go:79 devlake-1 | | main.main devlake-1 | | /app/server/main.go:33 devlake-1 | | runtime.main devlake-1 | | /usr/local/go/src/runtime/proc.go:250 devlake-1 | | runtime.goexit devlake-1 | | /usr/local/go/src/runtime/asm_amd64.s:1598 devlake-1 | Wraps: (2) plugin.Open("bin/plugins/minimal_plugin/minimal_plugin"): plugin already loaded devlake-1 | Wraps: (3) plugin.Open("bin/plugins/minimal_plugin/minimal_plugin"): plugin already loaded devlake-1 | Error types: (1) *withstack.withStack (2) *errutil.withPrefix (3) *errors.errorString ``` I check my container there is only one minimal_plugin.so in the container, but I don't know why the devlake plugin framework say it already loaded, from the github.com/apache/incubator-devlake/core/runner.LoadGoPlugins code it is pretty straight forward just look all the folder and find each .so file then load each one... so I really confused. ### What do you expect to happen the plugin can be loaded successfully ### How to reproduce Here is what I did: I put my plugin code in a separate repo, build it to a .so file, then use a Dockerfile to copy this .so file to /app/bin/plugins and build a new image, then use the default docker-compose-dev.yaml in devlake repo to launch this image ``` FROM golang:1.24 AS builder COPY . /app WORKDIR /app RUN go mod tidy RUN go build -buildmode=plugin -o /app/bin/plugins/minimal_plugin.so plugin.go # Use the official DevLake image as base FROM devlake.docker.scarf.sh/apache/devlake:latest AS devlake # Switch to root to handle permissions USER root # Remove all existing plugins to ensure a clean slate # This helps rule out conflicts with *any* built-in plugin #RUN rm -rf /app/bin/plugins/* # Ensure the directory exists and has correct permissions too (belt and suspenders) RUN mkdir -p /app/bin/plugins/minimal_plugin && chmod -R 755 /app/bin/plugins/minimal_plugin # Copy ONLY the minimal plugin COPY --from=builder /app/bin/plugins/minimal_plugin.so /app/bin/plugins/minimal_plugin/minimal_plugin.so # Switch back to devlake user USER devlake ``` build this docker image as devlake-minimal-test and update the docker compose yml code like below: ``` ...... devlake: image: devlake-minimal-test:latest ports: - 8080:8080 restart: always volumes: - devlake-log:/app/logs env_file: - ./.env environment: LOGGING_DIR: /app/logs TZ: UTC depends_on: - mysql ...... ``` ### Anything else _No response_ ### Version v1.0.1 ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
