UPDATE(@chanseokoh): this issue was re-purposed to track the potential problem that Jib may be unable to send client certificate in secure TLS connection: https://github.com/GoogleContainerTools/jib/issues/2226#issuecomment-573116497
Original comment follows below.
Environment:
Description of the issue:
When the build fails, the actual error message is null. This causes an NPE when the exception is wrapped thus hiding the original exception.
Expected behavior:
The actual error is shown
Steps to reproduce:
mvn clean package jib:build
Additional Information:
The target docker registry is spawned from minishift (on the same host).
Using a different docker registry works fine.

PS: Do you have any hint what the original error could have been?
The original exception is of IOException. I'm curious what the exception class is. If you modify the following code in RegistryEndpointCaller.java, you'll be able to check what it is.
} catch (IOException ex) {
logError("I/O error for image [" + serverUrl + "/" + imageName + "]:");
logError(" " + ex.getMessage());
logErrorIfBrokenPipe(ex);
if (ex instanceof SSLException) {
throw new InsecureRegistryException(url, ex);
}
throw ex;
}
For us, I think we should also log the exception class there and do not assume verifyNotNull() in JibBuildRunner.

This looks like a bug(?)/imperfection in the apache http client library as ClientProtocolException seems to swallow the message.
But I don't understand that cause either. Does it attempt to connect to the registry using HTTP instead of HTTPS? (The registry uses a self-signed certificate + allowInsecureRegistries=true).
Jib (JVM) failed to verify the server over HTTPS:
[WARNING] Cannot verify server at https://192.168.1.2:2376/v2/. Attempting again with no TLS verification.
So it attempts the port again with no TLS verification. But it also failed even when not verifying the server:
[WARNING] Failed to connect to https://192.168.1.2:2376/v2/ over HTTPS. Attempting again with HTTP.
So Jib attempted speaking plain-HTTP on the port 2376. I suspect the port 2376 doesn't speak HTTP, so that's why you get ClientProtocolException and the message "(t)he server failed to respond with a valid HTTP response."
What does curl -v -k https://192.168.1.2:2376/v2/ say? Maybe write a simple Java program to connect to https://192.168.1.2:2376/v2/ and see if it works. I wonder if the server uses some kind of SSL-related algorithm that the JVM cannot handle. Another possibility is that the port 2376 doesn't speak TLS/SSL at all.
BTW, note that in general, if you installed the self-signed certificate to the JVM truststore correctly, you don't even need to set allowInsecureRegistries.

I know. It was supposed to be a quick test...
I think there's a problem.
curl: (35) error:14094412:SSL routines:ssl3_read_bytes:sslv3 alert bad certificate
Ah, I don't know much about this stuff, but reading https://community.letsencrypt.org/t/curl-35-errorssl-routinessslv3-alert-bad-certificate/85239/5, the client has to present a certificate too? (I'm just talking gibberish here.)
You are right, seems to be a missing client certificate.
txt
$ curl --cacert ca.pem --key key.pem --cert cert.pem https://192.168.99.100:2376/v2/
{"message":"page not found"}
I will try to setup the truststore/keystore appropriately. If that doesn't work I will just build the tars in maven and then load them using the docker cmd (Which is what I'm currently doing/using).
Feel free to close this issue or use it for tracking purposes of the "NPE hides Exception" bug.
Please update here how it goes. I may be wrong, but maybe the client certificate should be added to the keystore (while the server certificate to the truststore): https://blog.kunicki.org/blog/2015/09/10/ssl-client-certificates-on-the-jvm/ Hope it works.
I added the certs/keys to my store and run it again:

Maybe java doesn't support this kind of SSL impl?
Unfortunately this error message is relatively inexpressive.
Sorry, no idea. Maybe try simple code like here or SSLPoke against https://192.168.1.2:2376/v2/. And perhaps worth trying different JVMs (Java 8, Java 11, ...) on different machines.
Using jshell is another way.
I didn't manage to get it running. I have no more time to try this (I'm not even sure this is related to Java at all). Thanks for your help.
Please fix the NPE in the error message anyway.
Actually, I remembered someone told us an issue that Jib isn't sending a client certificate a while ago. Although I haven't verified myself, this may be the cause: https://github.com/googleapis/google-http-java-client/issues/904
@ST-DDT 2.0.0 was released and fixes the NPE. But it's very possible that Jib is unable to send a client certificate due to some problem in the Google HTTP Client. I'll re-purpose this issue for tracking.
Fixed by #2592. See #2585 for more details.
@ST-DDT we released Jib Gradle 2.5.0 and Jib Maven 2.5.2 and believe this is fixed.
