[lephix]

I set the apiclient correctly, I can get pod, replace pod etc,.
But when I ran the example of exec and attach get following errors:

What version of the library are you running?

This looks like the same issue as #180 but that has been fixed...

[lephix]

@brendandburns I forgot to add the dependency info.

    <dependency>
        <groupId>io.kubernetes</groupId>
        <artifactId>client-java</artifactId>
        <version>3.0.0</version>
    </dependency>

@lephix is this resolved for you? I am facing the exact same issue with the same version of client library.

[lephix]

@radhe-sravan No. I am using fabric8 library for this func instead.
