我在尝试使用LBAPI时收到IllegalArgumentException。有人可以帮我吗？

最佳答案

我认为README for Rally-Lookback-Toolkit中的示例通过名称指定工作区的方式具有误导性/错误性：

lookbackApi.setWorkspace("myworkspace");

当我这样做时，我从LBAPI中看到以下错误：

Lookback Exception com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1

REST URL中实际上需要的是Workspace ObjectID而不是名称。因此，如果您在代码中设置了Workspace ObjectID：

this.lookback.setWorkspace("12345678910");

我认为查询应该为您工作。
