java.util.NoSuchElementException: key [aws-ec2] not in the list of providers or apis: {}

[Nirmal Fernando]

Hi All,

I'm getting [1] below, when I try to do [2]. I've installed following jars in my OSGi environment.

id    State       Bundle
15    ACTIVE      aws_ec2_1.5.0_beta.1_1.0.0
40    ACTIVE      ec2_1.5.0_beta.1_1.0.0
59    ACTIVE      jclouds_compute_1.5.0_beta.1_1.0.0
60    ACTIVE      jclouds_core_1.5.0_beta.1_1.0.0
61    ACTIVE      jclouds_enterprise_1.5.0_beta.1_1.0.0
62    ACTIVE      jclouds_slf4j_1.5.0_beta.1_1.0.0
63    ACTIVE      jclouds_sshj_1.5.0_beta.1_1.0.0

What could be the reason? Appreciate any help!

[1]
java.util.NoSuchElementException: key [aws-ec2] not in the list of providers or apis: {}
    at org.jclouds.ContextBuilder.newBuilder(ContextBuilder.java:136)

                .credentials(identity, credential)

I see you are using the 1.5.0.beta.1 version. This is the last version of jclouds that makes use of OSGi fragments, so its possible that you'll need to refresh bundle 60 (jclouds core) so that the compute bundle can get attached to it. This has been changed on trunk and will not be needed in beta.2 or any future version of jclouds.

I think the exact reason for the error I'm seen can be found in here http://aries.apache.org/modules/spi-fly.html

I'm gonna try out the solution provided by Apache Aries!!

Hopefully it works well !!

Yes, that did the trick! Seems like JClouds should use Apache Aries' SPI-FLY component's dynamic bundle.

Hi Nirmal,

I've committed a change that will help any OSGi users to discover providers without the need of using external tools such as spi-fly or implementing their own patterns for discovery.

The change has been part of the beta.2 candidate which is available for testing at: https://oss.sonatype.org/content/repositories/orgjclouds-549/

Could you please have a look and let us know if that solves your problems?

Thanks,

[Nirmal Fernando]

Thanks for the prompt action! I'm downloading the jars ... :)

Hi All,

With beta-2 packs, all went well!!! :-) Awesome work Ioannis!!

Appreciate very much!!

[Nirmal Fernando]

Hi Ioannis,

Seems like with your approach I should set a higher bundle start value to provider jars, otherwise jclouds-core won't pick it up.

Scenario: EC2 provider bundle get started before jcloud-core bundle, and bundle listener in core can't see any bundle event occurring from that EC2 provider bundle, since it is already started. Hence, EC2 provider won't get added!

Can you see any code level solution to this problem?

[Ioannis Canellos]

I guess we could have the core bundle scan any of the existing ones.

[Chris Custine]

How about adding that init() to the bundlelistener (same as jclouds-karaf version) and just calling it from the activator?  I am also wondering if ApiMetadata is also necessary here?  Did that complicate things too much given the release schedule?

It's necessary for openstack to work, and I reported in another thread!

Hi

I am getting this problem using jclouds 1.5.1 when compiling with the maven-shade-plugin or the maven-assembly-plug-in, any ideas how I might go about fixing it?

John.

[Adrian Cole]

Hi, John.

This is probably related to serviceloader references. Here's an
example pom that deals with this:

Hi John,

Not sure, whether this helps.

I used maven shade plugin like following in my project's pom.

Hi Adrian, Nirmal

 

Adrians suggestion worked brilliantly thanks. Thanks for the response Nirmal but I tired Adrian's solution first and it did the trick.

 

Thanks to both for the quick response.

 

John.
