Why does bazel require me to add dependencies of the library my project is dependent on for Go?

Question

I am working with the echo framework. Hence, my project is directly dependent on github.com/labstack/echo/v4 . Accordingly, I have added it to my go.mod and WORKSPACE file. However, bazel build fails and only works if I add the following 2 dependencies.

github.com/labstack/gommon
github.com/valyala/fasttemplate

Why is this required, and is there any way around it?

Answer 1

These modules are required because they are dependencies of the echo module and therefore required to build the code. See the dependencies listed in echo's go.mod file :

[...]
github.com/labstack/gommon v0.3.0
github.com/valyala/fasttemplate v1.2.1
