If I use in s2i build on openshift with wildfly images and custom settings.xml (even empty) through secret MAVEN_ARGS, e.g.

.addEnvVariable("MAVEN_ARGS", "install -s /etc/" + SECRET_NAME + "/" + SETTINGS_XML)

I experience significant increase (approximately 7x bigger) in build time

EAP OpenShift E2E Testsuite ........................ SUCCESS [16:35 min]

compared to

EAP OpenShift E2E Testsuite ........................ SUCCESS [02:31 min]

Without -s option.

We did not experienced similar situation with EAP 8 images. Where build time is about 5 minutes. And if "-s" is used or not does not make difference.
