List of Deployment Projects

[Jason Schwanz]

Java novice here, and I've been sitting at this road block for long enough. I'm trying to write my first add-on, and I want to generate an list of all deployment projects. I've been focusing on DeploymentProjectDaoImpl and ViewAllDeploymentProjects, but no matter how I implement/emulate those I end up with NPE in the end. I expect there is some simple solution I'm missing, and would appreciate any guidance.

Update:

Code and stacktrace.

final ViewAllDeploymentProjects deployProjects = new ViewAllDeploymentProjects(); 
List<DeploymentProject> deploy = deployProjects.getDeploymentProjects();

@Silviu Burcea I've posted code and stacktrace results of the methods I've tried. From exploring the source code for examples my Update 2 is doing what appears to work in other places, but I still get a NPE.

[Krystian Brazulewicz]

Jason - download Bamboo source code and look for examples. In your code you should never use DAO directly, use DeploymentProjectService and other Service/Managers

[Jason Schwanz]

I had previously downloaded the source, and that's where I found com.atlassian.bamboo.deployments.projects.actions.ViewAllDeploymentProjects (via viewAllDeploymentProjects.ftl). I've updated the question with my latest attempt by implementing the DeploymentProjectService from the example of ViewAllDeploymentProjects.

[Jason Schwanz]

@Krystian Brazulewicz I've gone throughout the source code, and what I'm attempting in Update 2 is what I find. Do you have any guidance for my next steps?

[Jason Schwanz]

I've updated the question with stacktrace and code snippets for both methods I've attempted.

[Silviu Burcea]

NPEs are the easiest to fix. Show us the stacktrace and your code.
