Question

I have a Maven project and written some Selenium TestNG scrips in it.
Jenkins installed on the Linux server and while I'm trying to run the Selenium tests from Jenkins getting this Maven error,
[ERROR] Plugin org.apache.maven.plugins:maven-compiler-plugin:3.5 or one of its dependencies could not be resolved:

Answer 1

Your Jenkins server failed to download a dependency from the Maven repository.
This is mentioned in the error message:
Connect to repo.maven.apache.org:443 [repo.maven.apache.org/23.235.47.215] failed: Connection timed out
This may be a temporary connectivity problem with your server, so you could try again.
If this error keeps happening, then check with your network administrator that the Jenkins server has access to that hostname and port, as it may be blocked by a firewall.
