Invalid Auth config file when using credsStore

See original GitHub issue

Using a “credsStore” configuration for auth in ~/.docker/config.json causes AuthConfigFile to fail with an IOException.

com.github.dockerjava.api.exception.DockerClientException: Failed to parse dockerCfgFile
	at com.github.dockerjava.core.DefaultDockerClientConfig.effectiveAuthConfig(DefaultDockerClientConfig.java:268)
	at com.github.dockerjava.core.DockerClientImpl.pullImageCmd(DockerClientImpl.java:215)

	at com.github.dockerjava.core.DefaultDockerClientConfig.effectiveAuthConfig(DefaultDockerClientConfig.java:266)

After a little debugging it looks like the json parsing fails silently a little earlier in AuthConfigFile.java:

com.fasterxml.jackson.databind.JsonMappingException: Can not instantiate value of type [map type; class java.util.LinkedHashMap, [simple type, class java.lang.String] -> [simple type, class com.github.dockerjava.api.model.AuthConfig]] from String value ('osxkeychain'); no single-String constructor/factory method

Same issue. Gradle build always fails on macOS with latest version of https://github.com/bmuschko/gradle-docker-plugin and docker-java version 3.0.6.

config.json:

{
  "auths": {
    "https://index.docker.io/v1/": {}
  },
  "credsStore": "osxkeychain"
}

The error still happens with version 3.0.14 when using com.bmuschko.docker-remote-api gradle plugin.

~/.docker/config content is

{
  "stackOrchestrator" : "swarm"
}

Docker version is Version 2.0.0.0-mac81 (29211), Engine Version: 18.09.0 Securely store Docker logins in macOS keychain is unchecked in Preference.

Please advise…
