Build Failing again and again

Pls,
211068-error.txt (31.2 KB)
help me to understand the error.

Hi, the error is

jarsigner: Certificate chain not found for: Matrix. Matrix must reference a valid KeyStore key entry containing a private key and corresponding public key certificate chain.

Here’s one case where it was related to the alias name. Maybe that could help your case?

Do I need a new Key?

Hi, if you have generated the keystore file according to instructions here you shouldn’t need to generate it again. If you’ve missed any of the steps (for example there’s no password) then yes. Otherwise just check that in the build service the info is correct (alias name matches the name in the keystore etc.)
