Hi I’m trying to build for the first time, but I am getting stuck with this gradle failure
Copy code
Execution failed for task ':metadata-ingestion:codegen'.
> Process 'command 'bash'' finished with non-zero exit value 1
b
my guess is that 
jq
is not installed can you try running the task 
./gradlew :metadata-ingestion:codegen --info
and see what it says
t
ok thanks, I’ll try that

* What went wrong:
Failed to create Jar file /Users/.../.gradle/caches/jars-8/99bb3272baeb9a2315d3e66fad30256e/buildSrc.jar.

SHould be. I’ll double check
Ah, I wasn’t that time because I tried in a different shell. But after setting the right java home, I tried again and got the same error as before

yup

Thanks for your help!
b
Woohoo! Nice teamwork.

I tried switching back to the latest release tag, but it seems to be the same error.
b
no idea. 🤷‍♂️ I normally skip docs-website tasks because i don't need the documentation site 🙂 (by commenting out docs-website in ./settings.gradle)
b
I think this may be related to your python version
Cc @dazzling-judge-80093 - I also saw this earlier
t
Thanks guys. The website doesn’t seem to mention a python version. I will see what I have and try again. https://datahubproject.io/docs/developers/#common-build-issues
FYI I made sure that the default ‘python’ was 3.9.2, cleaned and tried again. I got past that error but stuck on other after a few more tries. I have changed to building piecewise as written on the Developer’s Guide page and that seems to have been successful. Now trying to deploy locally what was built.

Okay please let us know - This is a newly introduced issue we need to address on our side
