Overriding Builder Image Scripts by "scripts: URL" in buildConfig doesn't work under proxy

Issue

• The documentation gives an example of overriding the builder image scripts using a URL:

scripts: "http://somehost.com/scripts_directory"

• However, when I tested this feature under the proxy, the build always fialed.

$ oc logs test-eap-proxy-5-build
