【问题描述】：
我们正在尝试在我们的 Vaadin 项目中初始化一个休眠数据库，但它会引发以下错误。 我们一直在寻找几天，但到目前为止还没有解决方案，我们没有想法。希望任何人都可以提供帮助。 我们正在使用 NetBeans。

Needed when using the widgetset optimizer (custom ConnectorBundleLoaderFactory).
For widgetset compilation, vaadin-client-compiler is automatically added on the
compilation classpath by vaadin-maven-plugin so normally there is no need for an
explicit dependency.

【问题讨论】：
-
你在混合不同版本的 slf4j 吗？我看到 1.5 和 1.7
-
你的类路径上有 SLF4J-Log4J 和 SLF4J-JDK14。您应该只有一个 SJLF4 绑定（实现）。
-
感谢您的回复。 Netbeans 不允许我删除 SLF4J-Log4J，所以我删除了 SLF4J-JDK14 但结果是一样的。
-
执行
mvn dependency:tree并将您的输出粘贴到此处。
