我们使用TFS SDK版本11.0.0库来连接“TFS：2015 update 3”以获取数据或创建缺陷（Bug，Issue，...）。但是，在使用workItem.save（）方法创建新缺陷或更新现有缺陷时，我们会遇到NullPointerException。我们是否使用正确版本的TFS SDK和'TFS 2015 update 3'？我们是否需要从TFS 2015 Server配置任何特殊功能，以便TFS SDK可以创建新的缺陷？如果我们做错了，请告知我们，如果您需要更多信息，请告诉我们。
你知道我们在哪里可以得到所有版本的TFS SDK吗？
非常感谢你。
Maven配置：
<dependency>
<groupId>com.microsoft.tfs.sdk</groupId>
<artifactId>com.microsoft.tfs.sdk</artifactId>
<version>11.0.0</version>
</dependency>
WorkItem item = client.newWorkItem(selectedWorkItemType);
if (item == null) {
LOG.warn("Unable to create item in TFS.");
return null;
}
setValues(item, fieldsMap, description);
String itemId = null;
if (item.isValid()) {
item.save(); // --> It throws NullPointerException after calling this save() method
itemId = String.valueOf(item.getID());
}
使用Java代码更新存在的缺陷：
int workItemId = 6;
WorkItem itemExisted = client.getWorkItemByID(workItemId);
if(itemExisted != null && itemExisted.isValid()){
System.out.println(">>>>>>>>>>>>>" + itemExisted.getTitle());
itemExisted.setTitle("Updated to New Title Bug");
itemExisted.save(); // It throws NullPointerException after calling this save() method
}
