编辑：最初的问题是关于“编译失败”，但更准确地说“在应用程序上下文加载”
我正在研究计费系统。作为下一次迭代的一部分，我需要创建一个发票文档。
我们正在与Jasper Reports合作。使用Jasperstudio制作并批准了文档的“设计”（我们将加载.jasper编译的文件）。
当我添加jasperreports依赖项（没有新类或任何新代码）时，问题就来了。
当我运行我的黄瓜测试以创建发票时，我在我的一个Spring存储库的自动装配期间得到了这个：
Internal Exception: java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost/my_database
我确实直接从mysql-connector-java（6.0.6）依赖，在此之前我没有遇到任何问题。
我认为这是一个依赖性问题，但我找不到它。
这是我的依赖树

任何暗示将不胜感激。
通过在POM中向下移动依赖项来解决该问题。
我的猜测是jasperreports进行某种初始化并且需要所有依赖项已经存在。但我无法弄清楚为什么会这样做。
谁能解释一下？
