Jira REST API时间跟踪空

Question

我的下面的代码是在我尝试获取时间跟踪我的问题时获取空指针异常，即使问题有时间跟踪，我正在使用此API：

        <groupId>com.atlassian.jira</groupId>

        <artifactId>jira-rest-java-client-api</artifactId>

        <version>2.0.0-m19</version>

    </dependency>

    <dependency>

        <groupId>com.atlassian.jira</groupId>

        <artifactId>jira-rest-java-client-core</artifactId>

        <version>2.0.0-m19</version>

    </dependency>

//

for (JiraFixVersion jiraFixVersion : listJiraFixVersionsProject) {
        Iterator<Issue> issues = JiraClientManager.getInstance().getSearchResultSet("project='" + jiraProject.getProjectName()
                + "' AND fixVersion =" + "'" + jiraFixVersion.getName() + "'").iterator();
        Integer sumEstimatedTimeHours = 0;
        while (issues.hasNext()) {
            Issue issue = issues.next();
            Integer estimatedTime =0;
            try {
//Here is NullPointerException
                TimeTracking timeTracking = issue.getTimeTracking();

                estimatedTime = timeTracking.getOriginalEstimateMinutes();
                System.out.println("ok "+issue.getKey());
            }catch(NullPointerException e){
                System.out.println("Time Tracking null "+ issue.getKey());
            }
            sumEstimatedTimeHours += estimatedTime;
        }
        returnMap.put(jiraFixVersion, sumEstimatedTimeHours);
    }

Answer 1

我通过以下方式解决了这个问题：

for (JiraFixVersion jiraFixVersion : listJiraFixVersionsProject) {

        Iterator<Issue> issues = JiraClientManager.getInstance().getSearchResultSet("project='" + jiraProject.getProjectName() + "' AND fixVersion =" + "'" + jiraFixVersion.getName() + "'" + " AND cf[10002] !=null").iterator();
        Double sumStoryPoints = 0.0;
        while (issues.hasNext()) {
            Issue issue = issues.next();
            String storyPoints = issue.getField("customfield_10002").getValue().toString();
            Double storyPointIssue = Double.parseDouble(storyPoints);
            sumStoryPoints += storyPointIssue;
        }
        returnMap.put(jiraFixVersion, sumStoryPoints);
    }

'customfield_1002'是我想要的字段，但是如果你真的想要那个对象TimeTracking，你必须提出另一个服务器请求，这将持续一些宝贵的时间，我不会推荐，但我会显示代码：

while (issues.hasNext()) {

            Issue issue = issues.next();
            try {
                Issue claim = JiraClientManager.getInstance().getRestClient().getIssueClient().getIssue(issue.getKey()).claim();
                TimeTracking timeTracking = claim.getTimeTracking();
                Integer estimatedTimeSeconds =(Integer) issue.getField("timeoriginalestimate").getValue();
                Double estimatedTimeHours = (estimatedTimeSeconds.doubleValue())/3600;
                System.out.println(estimatedTimeHours+" "+issue.getKey());
                sumEstimatedTimeHours += estimatedTimeHours;
            }catch(NullPointerException e){
                System.out.println("Time Tracking null "+ issue.getKey());
            }
        }
