java - 项目建立在本地但在 travis-ci 容器中失败

Question

首先，抱歉英语不好...

我创建了项目 spark-spring ( https://github.com/rascorp/spark-spring ) 以提供一种将 spring 上下文放入 spark-java 框架的简单方法。

我创建了一个测试来检查服务器是否启动并返回一个值。在我的个人电脑上运行，所有测试运行正常，但在 travis-ci 中，连接测试失败。

本地输出:

谁能帮我解决这个问题？

Answer 1

我找到问题了!

出现该问题是因为测试运行时服务方法不可用。要修复，我需要在运行测试之前调用以下代码。

/**
 * Waits for the spark server to be initialized.
 * If it's already initialized will return immediately
 */
Spark.awaitInitialization();
