Apache jclouds java.lang.NoSuchMethodError when using Rackspace in a Spring Boot application

I'm trying to integrate Apache Jclouds into a Spring Boot application I'm working on so that I can upload files to Rackspace Cloud Files(UK).

I've created a class which I'm creating as a Bean;

import com.google.common.io.ByteSource;
import com.google.common.io.Files;
import org.jclouds.ContextBuilder;
import org.jclouds.io.Payload;
import org.jclouds.io.Payloads;
import org.jclouds.openstack.swift.v1.features.ObjectApi;
import org.jclouds.rackspace.cloudfiles.v1.CloudFilesApi;
import org.springframework.web.multipart.MultipartFile;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;

/**
* Class WebStorage
*
*/
public class WebStorage {

private final String region = "lon";
private final String provider = "rackspace-cloudfiles-uk";

private String username;
private String apiKey;
private String container;
private String url;

private CloudFilesApi cloudFilesApi;

public WebStorage(String username, String apiKey, String container, String url) {
this.username = username;
this.apiKey = apiKey;
this.container = container;
this.url = url;

cloudFilesApi = ContextBuilder.newBuilder(provider)
.credentials(this.username, this.apiKey)
.buildApi(CloudFilesApi.class);
}

/**
* Accepts a MultipartFile and returns it as a File
* @param multipartFile the MultiPartFile to convert
* @return a new File
*/
public static File createFileFromMultipart(MultipartFile multipartFile) {
File file = new File(multipartFile.getOriginalFilename());

try {
file.createNewFile();
FileOutputStream fos = new FileOutputStream(file);
fos.write(multipartFile.getBytes());
fos.close();
} catch (IOException e) {
e.printStackTrace();
}

return file;
}

/**
* Send the file to the CDN and return it's full URL
* @param name the path/name of the file on the CDN
* @param theFile the file to upload to the CDN
* @return the full URL to the uploaded file on the CDN
*/
public String put(String name, File theFile) {
ObjectApi objectApi = cloudFilesApi.getObjectApi(region, this.container);

/* Upload the file */
ByteSource byteSource = Files.asByteSource(theFile);
Payload filePayload = Payloads.newByteSourcePayload(byteSource);
objectApi.put(name, filePayload);

return this.url + name;
}

}


I'm declaring the bean in the same place I'm declaring all other beans (which work fine);

@Bean
public WebStorage storage() {
return new WebStorage(
env.getProperty("voila.cdn.username"),
env.getProperty("voila.cdn.apikey"),
env.getProperty("voila.cdn.container"),
env.getProperty("voila.cdn.url")
);
}


But each time I run the application, the bean fails to load as a class not found error is generated when trying to create the bean.

I've included version 1.9.2 of jclouds in my pom file;

<dependency>
<groupId>org.apache.jclouds</groupId>
<artifactId>jclouds-all</artifactId>
<version>1.9.2</version>
</dependency>


Is someone able to tell my why I'm getting a class not found error? I'm not including any Google dependencies in my POM, so any that are available are being included by one of my dependencies.

Answer

This is a known issue in jclouds. See JCLOUDS-1160 and JCLOUDS-1166. Until those issues are fixed you won't be able to use jclouds with Spring Boot if you can't force a version of Gson <= 2.5.

Another option is to use the maven-shade-plugin to shade the jclouds dependencies and bundle Gson in it. This way you should be able to use the Gson version your environment needs, while jclouds uses the shaded one.
