java无法使用jclouds API将文件上载到azure blob

Question

我使用here给出的相同示例将我的文件上传到Azure blob。当我把它作为一个普通的Java项目代码运行时，它工作得很好，但是当我用它创建一个OSGi包并尝试同样的事情时，我得到了以下异常

有人能帮我吗

Answer 1

这是因为应用程序类路径中可能没有azureblob依赖项。确保你的pom中有这种依赖性。xml文件：

<dependency>
    <groupId>org.apache.jclouds.provider</groupId>
    <artifactId>azureblob</artifactId>
    <version>${jclouds.version}</version>
</dependency>
