当我尝试运行此代码时（问题示例取自此网站http://www.redmine.org/projects/redmine/wiki/Rest_api_with_java）：

    RedmineManager redmineManager = new RedmineManager("http://something.cz", "somekey"); //I changed these two parameters for security reasons when paste here
    System.out.println(redmineManager.getProjects().size()); //this works fine
    Issue issueToCreate = new Issue();
    issueToCreate.setSubject("This is the summary line 123");
    Issue newIssue = redmineManager.createIssue("test-project", issueToCreate); //this line throws exception

它以这个例外结束

同样的行为适用于任何其他“获取一些对象”（有效）和“创建一些对象”（无效）。

我正在使用 maven ( http://mvnrepository.com/artifact/com.taskadapter/redmine-java-api ) 及其对 1.23 版本的依赖，但是我尝试了 1.12.0 并引发了相同的异常。

我们使用的是最新的 redmine 2.5.1.stable，但是基于 stacktrace，redmine web 和这个 redmine api 之间的通信不会发生，因为在应用程序的“parseRespone”部分中抛出了异常。

不幸的是，根据与图书馆所有者的讨论，这个问题似乎仍未解决（或无法解决）：https ://github.com/taskadapter/redmine-java-api/issues/126

但是 GET 请求有效。对于 UPDATE/CREATE，您可以使用纯 API，如下所示。警告：禁用 SSL 是危险的，仅用于测试目的（例如“它甚至可以工作吗？”）
