Provided config file is sometimes not complete

    • Type: Bug

    • Priority: Minor
    • Component/s: config-file-provider-plugin

    • Environment:
      Jenkins LTS 2.83.1
      Config File Provider Plugin 2.16.4

      Sometimes when I tried to parse JSON config file I encountered following exception:

      net.sf.json.JSONException: Found starting '{' but missing '}' at the end. at character 0 of null

      It turns out that returned file was not complete. I reproduced the issue this way:

      node {
  for (int i = 0; i < 40; i++) {
    configFileProvider([configFile(fileId: 'file-id', variable: 'configfile')]) {
      readJSON(text: readFile(file: configfile))
    }
  }
}

      Printing file content to console proves that it is readed to early. Adding file existance check helps:

      node {
  for (int i = 0; i < 40; i++) {
    configFileProvider([configFile(fileId: 'file-id', variable: 'configfile')]) {
      if (fileExists(file: configfile)) {
        readJSON(text: readFile(file: configfile))
      } else {
        error("File '$configfile' not found")
      }
    }
  }
}
