我们正在使用Teamcity 9.0.3,我们尝试使用测试运行gradle构建.但是,它失败了以下异常:

[15:25:41][:test] Failed to find flowId for [com.stub.AppTest]
[15:25:41][:test] java.lang.NullPointerException: Failed to find flowId for [com.stub.AppTest]

[15:25:41][:test]   at java.lang.reflect.Constructor.newInstance(Constructor.java:422)

我使用gradle包装器和它的2.5版本以及用于构建的teamcity代理.我怎样才能解决这个问题？

我们在项目中使用hibernate验证器和动态类加载(通过加载类进入单独的类加载器).在我们意识到不需要该类之后,我们删除对类和类加载器的所有引用,然后GC收集它.

我们得到的结果:应用程序启动后的一段时间,java反射停止工作.

我正在开发一个将google oAuth2身份验证与google-api-client一起使用的应用程序。在webView中，我打开库提供给我的URL以访问accessToken并尝试进行身份验证。一切进展顺利，您需要确认在移动设备上使用帐户的步骤（https：//accounts.google.com/signin/challenge/az/2 ...）。我在设备上单击“是”，但是在webView中什么也没有发生。虽然，如果尝试在浏览器中执行相同的操作（使用库提供的url），则会发生使用代码获取accessToken的重定向到url。

有人可以遇到这样的问题，知道如何解决吗？

PS我尝试使用此处描述的方法“ https://github.com/mohamnag/javafx_webview_debugger ” 调试webView ，但没有帮助。
