My Java API将来自其他应用程序的团队成员与Rally进行比较。比较结果在Rally中更新。它需要参考项目名称和Res名称。
代码抛出＆＃34; java.lang.IndexOutOfBoundsException：索引：0，大小：0＆＃34;错误。我没有发现错误。有人可以帮忙吗？以下是代码和输出

答案 0 :(得分：1)
你有一个List（一个确切的ArrayList），它不包含任何内容（没有单个对象），你试图访问第一个对象（它不存在）。这就是错误告诉你的。您尝试访问索引0（列表中的第一个位置）但其中没有元素（因此大小为0）。它出现在第125行附近。由于您在问题中的格式似乎不正确，我只能猜测您问题中的哪一行是第125行（并且我不想通过以下方式读取125行代码方式）。所以我认为异常发生在这里：
JsonObject userObject = userQueryResponse.getResults().get(0).getAsJsonObject();
尝试追踪它。确保从userQueryResponse.getResults()返回的列表包含以下内容：
list = userQueryResponse.getResults();
System.out.println(list.size());
如果没有，那就是你的问题。如果您无法解决问题，请在不发布150行代码的情况下询问有关此问题的具体问题。
答案 1 :(得分：0)
get("_ref").toString()过去常用于旧版本，而您引用的代码较旧。当使用2.0.4 jar（默认情况下在生产中使用最新版本的WS API，v2.0）时，用get("_ref").getAsString()替换它的所有实例。
例如，
String userRef = userObject.get("_ref").toString();
将生成java.lang.NullPointerException：key == null
