searching in some places, I checked a NodeJs library called child_process and imported it into my project, after that, I declared a Promise to check the result of the exec method of this library. It was possible to get the execution data and treat it using a regexp to match a text or URL in the terminal.

Example:

function runApp(command) {
  setApplicationProperties();
  outputChannel.show();
  let promise = new Promise(resolve => {
    vscode.window.showInformationMessage(`Running App '${application_name}'...`);   
    let result = child.exec(command, {cwd: getWorkspaceDir()});
    result.stdout.on("data", (data) => {
        outputFilter = data;
        infoCatcher = outputFilter.match(/\w.+/gi);
        if(infoCatcher != null) outputChannel.append(`${infoCatcher[0]}\n`);
        urlCatcher = outputFilter.match(/(http|https)?:\/\/.+/gi);
        if(urlCatcher != null) vscode.env.openExternal(vscode.Uri.parse(urlCatcher[0]));
        resolve(); 
    });
});
return promise;

}

Thanks for the help.
