Hello, I’m getting a failure during build procedure. It is a random error that identical code produces failure only sometimes.

This is the relevant part from the error log:

I’m using Spoofax 2.4.1 version and has source dependency on org.metaborg:lang.java:1.0.0. The build was done by Maven CLI, and no other Spoofax instance(e.g. Eclipse) was running other than that.

That is odd, the StrategoMix.def file should not be copied to a temp directory, but to target/pack-sdf-includes instead. Is there any way I can try to build this locally to debug the issue?

I don’t have any for now. One thing I can confirm is that it happens when I build a project and build it again. Cleaning the project between two builds prevent this error to happen.

A bit late, but I was finally able to reproduce this issue and it should be fixed in the latest development build. Sorry it took so long.
