当我尝试在我的 mule 应用程序中使用 twitter 连接器时，我遇到了以下错误。

我的依赖项（和我的耳朵）中已经有了 mule-core。实际上，我的依赖项看起来很好..

    <dependency>
        <groupId>org.mule</groupId>
        <artifactId>mule-core</artifactId>
        <version>3.4.0</version>
        <type>jar</type>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.mule.modules</groupId>
        <artifactId>mule-module-twitter</artifactId>
        <version>LATEST</version>
    </dependency>

等等……等等……

这是堆栈：

org.mule.api.ConnectionException位于：

<dependency>
    <groupId>org.mule.modules</groupId>
    <artifactId>mule-module-devkit-support</artifactId>
    <version>3.4.0</version>
</dependency>

你的 POM 中有这种依赖关系吗？
