Teamcity checkout on agent error

[dharillo]

Greetings!

We are trying to use the Teamcity plugin with the "checkout on agent" configuration. This configuration works fine on Windows, but for a Linux agent the checkout does not work. The build fails event before the first build step:

Looking at the teamcity-agent.log the next exception trace appears:

Plugin version:

Do you know why may this be happening? I have looked at the plugin folder in the agent and the commons-lang.jar is there.

Hi,

The issue seems to be with an external library that we are linking in our plugin and it happens when checking the Java version.

What is your Java version? Could you try downgrading to Java 8 as a workaround?

Hi,

I had Java 11. I just tried downgrading to Java 8 and it works fine.

Will you deliver a new plugin version compatible with Java 11?

Regards!
