Compiling Jicofo error

Hi, Jitsi team, I failed to compile the Jicofo source code on Unbuntu 20, please advise me how to resolve this error?

[ERROR] Failed to execute goal on project jicofo-common: Could not resolve dependencies for project org.jitsi:jicofo-common:jar:1.1-SNAPSHOT: Failed to collect dependencies at org.jitsi:jicoco:jar:1.1-122-g7bba0d6: Failed to read artifact descriptor for org.jitsi:jicoco:jar:1.1-122-g7bba0d6: Could not transfer artifact org.jitsi:jicoco:pom:1.1-122-g7bba0d6 from/to jitsi-maven-repository-releases (jitsi-maven-repository/releases at master · jitsi/jitsi-maven-repository · GitHub): Transfer failed for PKIX path building failed: unable to find valid certification path to requested target → [Help 1]

Which java is that? Make sure you update to use latest maven.
Seems a local problem, the java you use cannot validate github certificates.

Hello, thank you for your reply, my compiler environment:
