Spring-boot: Spring Boot 1.4.0 Dependency Issue

[ptimsonbbc]

I get some strange google gson conflict when upgrading to 1.4.0. I am trying to use the s3proxy lib which uses jclouds

Sorry if this is the wrong place for this!

Code

        String endpoint = "http://127.0.0.1:8085";
        URI uri = URI.create(endpoint);
        Properties properties = new Properties();
        properties.setProperty("s3proxy.authorization", "none");
        properties.setProperty("s3proxy.endpoint", endpoint);
        properties.setProperty("jclouds.provider", "filesystem");
        properties.setProperty("jclouds.filesystem.basedir", "/tmp/s3proxy");

        ContextBuilder builder = ContextBuilder
                .newBuilder("filesystem")
                .overrides(properties);
        BlobStoreContext context = builder.build(BlobStoreContext.class);
        BlobStore blobStore = context.getBlobStore();

        S3Proxy s3Proxy = S3Proxy.builder().awsAuthentication("x", "x").endpoint(uri).keyStore("", "").blobStore(blobStore).build();
        s3Proxy.start();

        BasicAWSCredentials awsCredentials = new BasicAWSCredentials("x", "x");

        AmazonS3Client client = new AmazonS3Client(awsCredentials, new ClientConfiguration());
        client.setEndpoint(endpoint);
        GetObjectRequest objectRequest = new GetObjectRequest("bucket", "key");
        S3Object object = client.getObject(objectRequest);

        s3Proxy.stop();

This does not occur with Spring 1.3.7 Parent

[wilkinsona]

JCloud's Gson dependency is rather old. It depends on Gson 2.3.1 which is what Boot 1.3.x uses. 1.4 has upgraded to 2.7 with which JCloud appears to be incompatible. Ideally, JCloud would update their dependencies. Failing that you could try downgrading to Gson 2.3.1 (by overriding the gson.version property in your pom.xml or build.gradle).
