No idle compatible agents which can run this build

Hey!

Thank you for the response!

I did exactly as in the tutorial  

agent-side factory - EchoFactory:

public class EchoFactory implements CommandLineBuildServiceFactory {
    @NotNull
    @Override
    public CommandLineBuildService createService() {
        return new EchoService();
    }

    @NotNull
    @Override
    public AgentBuildRunnerInfo getBuildRunnerInfo() {
        return new AgentBuildRunnerInfo() {
            @NotNull
            @Override
            public String getType() {
                return EchoConstants.RUNNER_TYPE;
            }// String RUNNER_TYPE = "echoRunnerType";

            @Override
            public boolean canRun(@NotNull BuildAgentConfiguration buildAgentConfiguration) {
                return true;
            }
        };
    }
}

public class EchoService extends BuildServiceAdapter {
@NotNull
@Override
public ProgramCommandLine makeProgramCommandLine() throws RunBuildException {
final String message = getRunnerParameters().get(EchoConstants.MESSAGE_KEY);
return new SimpleProgramCommandLine(getRunnerContext(), "/bin/echo", Collections.singletonList(message));
}
}

The code looks fine. After a new plugin is installed on the server, the agent needs to upgrade to install the agent side of the plugin. Perhaps the agent did not have time to upgrade when you took the screenshot. You can verify if the plugin was delivered to the agent by checking the <agent_home_dir>/plugins directory. If the agent side of the plugin is still not on the agent, you can try to manually restart the agent. If that doesn't help either, try coping the agent side of the plugin from your plugin package (something along the lines of <your-plugin>.zip/agent/<your-plugin>-agent.zip) to the <agent_home_dir>/plugins directory and restart the agent again.
Normally, you shouldn't need to do that, however. The server should tell the connected agents to upgrade when there are new plugins that should be distributed to the agents.

Do I need to install the agent? or its suppose to work with the default agent?

It suppose to be at the /TeamCity_plugin/_plugin2/servers/2022.10/buildAgent/plugins/_plugin2-agent

because it looks like everything is there

And when I will succeed to make this plugin work... I need to have the option to let the user add a file to this upload? Do you know if there is a way it do it? Because I saw that the map with all the parameters are <string, string >

Thank you! 

Hi! When you package your plugin with maven, it should create a file named <your-plugin>.zip. Look inside that file, and find the <your-plugin>-agent.zip under the agent folder. What is the content of the <your-plugin>-agent.zip archive? The <agent_home_dir>/plugins/<your-plugin>-agent folder should have the same content.

Regarding the question, "I need to have the option to let the user add a file to this upload?", I am not sure I understand it. Could you rephrase it?

Hi Anatoly,

Yes everything looks fine.

when i deleted from my editEchoParameters.jsp the line:

"<jsp:useBean id="propertiesBean" scope="request" type="jetbrains.buildServer.controllers.BasePropertiesBean" %> 

suddenly I succeed to run this Build with the Echo runner, but i get an error(log is added)

here is the repository in git...

Thank you so much!

hey!
Thank you @Anatoly, it works now.

I would like to add an option to add a file to the plugin. Can you tell me how to do this in JSP and how to retrieve it in Java?

something like that:

Also, I am trying to make a string label a password but when I use

<input type="password" name="my_password"/>

instead of

<props:textProperty name="${messageId}" size="56" maxlength="100"/>

I am unable to receive the data in Java. how do i do it?

Thank you for your help.
