Cannot create instance of AWS class in bamboo plugin

Alistair Mackay_0t29g8

Hi,

I'm trying to develop a plugin for Bamboo 6.7.1 that utilises the AWS SDK.

I have this in my project POM. 

 <dependency> 
    <groupId>com.amazonaws</groupId> 
     <artifactId>aws-java-sdk</artifactId> 
      <version>1.4.7</version> 
      <exclusions> 
          <exclusion> 
             <groupId>commons-logging</groupId> 
             <artifactId>commons-logging</artifactId> 
          </exclusion> 
          <exclusion> 
           <groupId>stax</groupId> 
           <artifactId>stax-api</artifactId> 
          </exclusion> 
       </exclusions> 
       <scope>provided</scope> 
   </dependency>

 ...which seems to agree with other code I've seen using AWS SDK - and that the AWS libraries within Bamboo 6.7.1 are using AWK SDK 1.4.7

All goes well until I try to use the STS Assume Role call

import com.amazonaws.services.securitytoken.AWSSecurityTokenServiceClient;
import com.amazonaws.services.securitytoken.model.AssumeRoleRequest;

...

AWSSecurityTokenServiceClient sts = new AWSSecurityTokenServiceClient(buildServerCredentials);

// The following throws exception on plugin load if present:
AssumeRoleRequest req = new AssumeRoleRequest();

This error usually occurs when your plugin imports a package from another bundle with a specific version constraint and either the bundle providing that package doesn't meet those version constraints, 
or there is no bundle available that provides the specified package. For more details on how to fix this, see https://developer.atlassian.com/x/mQAN

Stuck :-(

Hi Alistair,

Those OSGi wiring errors are notoriously tricky to analyze, but your first steps should be to verify that the missing package is:

• … actually exported by Bamboo - see Using the OSGi Browser for details.
• … actually imported by your app - you can use the OSGi Browser mentioned above for that as well, but also directly look into the Import-Package declarations in the "/META-INF/MANIFEST.MF" file generated and included with your apps jar file.

That being said, and given that the AWS SDK bundled with Bamboo is rather outdated, we use an alternative approach in our AWS related apps - explicitly exclude the AWS SDK from your main Bamboo API dependency declaration, and then add your own dependencies for the respective SDK Maven modules you want to use in your POM with scope "compile".

While this will result in a bigger jar file, you'll end up with much more control over the SDK features available to your app (i.e. you can update the AWS SDK version as needed), and also less potential for OSGi conflicts (you might still run into some inverse ones that you need to exclude from your compile scope declarations in turn, e.g. the 'commons-logging' one, but I can't say for sure what is needed against Bamboo 6.7.1).

PS: Depending on what you are trying to achieve, you might want to take a look at our (commercial) offerings Identity Federation for AWS (SSO and temporary AWS credentials for reuse in e.g. Bash or PowerShell script tasks) and Tasks for AWS (a large collection of Tasks covering a wide range of AWS services, including CloudFormation).
