[Git config store] Username & password authentication config is overridden by idRsa

I'm using the config component with git config store. My config files are stored in a private git repo and I'm authentic by using username and password, which is set via:

new ConfigStoreOptions()
                        .setType("git")
                        .setConfig(new JsonObject()
                                .put("url", ...)
                                .put("path", "local")
                                .put("filesets", ...)
                                .put("user", "user")
                                .put("password", "password");

But I'm not speified a idRsaKeyPath attribute, it always says I don't provide a CredentialsProvider:

org.eclipse.jgit.api.errors.TransportException: https://github.com/xxx/xxx.git: Authentication is required but no CredentialsProvider has been registered

I've checked the source code, these lines may overrides the pervious CredentialsProvider which is set by username and password:

vertx-config/vertx-config-git/src/main/java/io/vertx/config/git/GitConfigStore.java

Line 97 in 037932a

if(Objects.nonNull(configuration.getString("idRsaKeyPath"))){

vertx-config/vertx-config-git/src/main/java/io/vertx/config/git/GitConfigStore.java

Line 118 in 037932a

transportConfigCallback = null;

Is it a bug? I'm looking for your response, thanks.

These lines do not override the CredentialProvider.
I'm more worried by

vertx-config/vertx-config-git/src/main/java/io/vertx/config/git/GitConfigStore.java

Line 155 in 037932a

.setTransportConfigCallback(transportConfigCallback)
