Error creating JClouds SwiftApi: Provider org.jclouds.openstack.keystone.v2_0.KeystoneApiMetadata could not be instantiated

Question

I have some code for connecting to a JClouds swift storage container which works fine in its own test area, but once I integrate into my project, I get an error:

Exception in thread "main" java.util.ServiceConfigurationError: org.jclouds.apis.ApiMetadata: Provider org.jclouds.openstack.keystone.v2_0.KeystoneApiMetadata could not be instantiated: java.lang.IllegalStateException: java.lang.reflect.InvocationTargetException

This is the code which fails on the ContextBuilder line:

private SwiftApi swiftApi;

public JCloudsConnector(String username, String password, String endpoint) {
      String provider = "openstack-swift";

      Properties overrides = new Properties();
      overrides.setProperty("jclouds.mpu.parallel.degree", "" + Runtime.getRuntime().availableProcessors());

      swiftApi = ContextBuilder.newBuilder(provider)
            .endpoint(endpoint)
            .credentials(username, password)
            .overrides(overrides)
            .buildApi(SwiftApi.class);
}

I am using the same dependencies (JClouds version 1.7.3) so I can't understand what the problem might be since both are run in the same environment.

Which version of Guava do you have in the classpath? Also, which version of the JVM are you running? — Ignasi Barrera, Aug 04 '14 at 15:11
Jclouds 1.7.3 depends on Guava 15.0 and won't work with greater versions in that version of the JVM. Can you stick to Guava 15.0? — Ignasi Barrera, Aug 04 '14 at 15:51
Don't put SOLVED in the title of your questions, or answer your questions in the question. Post a separate answer instead, and mark it completed by clicking the checkmark next to the answer. — Robert Harvey, Aug 04 '14 at 16:13

Thanks to Ignasi Barrera, I was able to sort this by adding an entry for Guava 15.0 in my maven POM file:

<dependency>
    <groupId>com.google.guava</groupId>
    <artifactId>guava</artifactId>
    <version>15.0</version>
</dependency>
