@kristoffSC @grzegorz8 the 1.18.1 job is failing with

14:50:32,522 [INFO] ------------------------------------------------------------------------

cat: target/site/jacoco/index.html: No such file or directory

Error: Process completed with exit code 1.

This looks like an infrastructure issue - as the build is successful then there is a cat error.

@kristoffSC @grzegorz8 it looks like the build is successful but fails - is the machine running out of disk space / lost access to something maybe?

[kristoffSC]

I will take a look why build fails.

[davidradl]

@AdrianVasiliu thank you very much for your detailed review, I really appreciate it. Great feedback :-)

[davidradl]

@kristoffSC a gentle nudge, we are looking to adopt this change, any news on the build issue?

[MarekMaj]

Hi @davidradl, we merged changes related to the build issue. Could you please rebase your commit?

[davidradl]

@MarekMaj thanks for making this change - it works for 2 of the releases bu not for 1.18.1, where I now see the CI fail with error

I suspect this is related to your recent jakoco commit

[MarekMaj]

@davidradl indeed, for PR created from forked repositories it caused problems due to insufficient permissions. I tested build again using forked repo, please rebase your code again:)

[davidradl]

@kristoffSC @MarekMaj hope to get to this this week. Thanks for your feedback.
