Service Fabric plug-in for Eclipse Java application development
Eclipse is one of the most widely used integrated development environments (IDEs) for Java developers. In this article, we describe how to set up your Eclipse development environment to work with Azure Service Fabric. Learn how to install the Service Fabric plug-in, create a Service Fabric application, and deploy your Service Fabric application to a local or remote Service Fabric cluster in Eclipse Neon.
Install or update the Service Fabric plug-in in Eclipse Neon
You can install a Service Fabric plug-in in Eclipse. The plug-in can help simplify the process of building and deploying Java services.
Ensure that you have the latest version of Eclipse Neon and the latest version of Buildship (1.0.17 or a later version) installed:
- To check the versions of installed components, in Eclipse Neon, go to Help > Installation Details.
- To update Buildship, see Eclipse Buildship: Eclipse Plug-ins for Gradle.
- To check for and install updates for Eclipse Neon, go to Help > Check for Updates.
To install the Service Fabric plug-in, in Eclipse Neon, go to Help > Install New Software.
- In the Work with box, enter http://dl.microsoft.com/eclipse.
- Select the Service Fabric plug-in, and then click Next.
- Complete the installation steps, and then accept the Microsoft Software License Terms.
If you already have the Service Fabric plug-in installed, make sure that you have the latest version. To check for available updates, go to Help > Installation Details. In the list of installed plug-ins, select Service Fabric, and then click Update. Available updates will be installed.
If installing or updating the Service Fabric plug-in is slow, it might be due to an Eclipse setting. Eclipse collects metadata on all changes to update sites that are registered with your Eclipse instance. To speed up the process of checking for and installing a Service Fabric plug-in update, go to Available Software Sites. Clear the check boxes for all sites except for the one that points to the Service Fabric plug-in location (http://dl.microsoft.com/eclipse/azure/servicefabric).
If Eclipse isn't working as expected on your Mac, or needs you run as super user), go to the ECLIPSE_INSTALLATION_PATH folder and navigate to the subfolder Eclipse.app/Contents/MacOS. Start Eclipse by running
Create a Service Fabric application in Eclipse
In Eclipse Neon, go to File > New > Other. Select Service Fabric Project, and then click Next.
Enter a name for your project, and then click Next.
In the list of templates, select Service Template. Select your service template type (Actor, Stateless, Container, or Guest Binary), and then click Next.
Enter the service name and service details, and then click Finish.
When you create your first Service Fabric project, in the Open Associated Perspective dialog box, click Yes.
Your new project looks like this:
Build and deploy a Service Fabric application in Eclipse
Right-click your new Service Fabric application, and then select Service Fabric.
In the submenu, select the option you want:
- To build the application without cleaning, click Build Application.
- To do a clean build of the application, click Rebuild Application.
- To clean the application of built artifacts, click Clean Application.
From this menu, you also can deploy, undeploy, and publish your application:
- To deploy to your local cluster, click Deploy Application.
In the Publish Application dialog box, select a publish profile:
An alternate way to deploy your Service Fabric application is by using Eclipse run configurations.
- Go to Run > Run Configurations.
- Under Gradle Project, select the ServiceFabricDeployer run configuration.
- In the right pane, on the Arguments tab, for publishProfile, select local or cloud. The default is local. To deploy to a remote or cloud cluster, select cloud.
- To ensure that the proper information is populated in the publish profiles, edit Local.json or Cloud.json as needed. You can add or update endpoint details and security credentials.
- Ensure that Working Directory points to the application you want to deploy. To change the application, click the Workspace button, and then select the application you want.
- Click Apply, and then click Run.
Your application builds and deploys within a few moments. You can monitor the deployment status in Service Fabric Explorer.
Add a Service Fabric service to your Service Fabric application
To add a Service Fabric service to an existing Service Fabric application, do the following steps:
Right-click the project you want to add a service to, and then click Service Fabric.
Click Add Service Fabric Service, and complete the set of steps to add a service to the project.
Select the service template you want to add to your project, and then click Next.
Enter the service name (and other details, as needed), and then click the Add Service button.
After the service is added, your overall project structure looks similar to the following project:
Edit Manifest versions of your Service Fabric Java application
To edit manifest versions, right click on the project, go to Service Fabric and select Edit Manifest Versions... from the menu dropdown. In the wizard, you can update the manifest versions for application manifest, service manifest and the versions for Code, Config and Data packages.
If you check the option Automatically update application and service versions and then update a version, then the manifest versions will be automatically updated. To give an example, you first select the check-box, then update the version of Code version from 0.0.0 to 0.0.1 and click on Finish, then service manifest version and application manifest version will be automatically updated to 0.0.1.
Upgrade your Service Fabric Java application
For an upgrade scenario, say you created the App1 project by using the Service Fabric plug-in in Eclipse. You deployed it by using the plug-in to create an application named fabric:/App1Application. The application type is App1AppicationType, and the application version is 1.0. Now, you want to upgrade your application without interrupting availability.
First, make any changes to your application, and then rebuild the modified service. Update the modified service’s manifest file (ServiceManifest.xml) with the updated versions for the service (and Code, Config, or Data, as relevant). Also, modify the application’s manifest (ApplicationManifest.xml) with the updated version number for the application and the modified service.
To upgrade your application by using Eclipse Neon, you can create a duplicate run configuration profile. Then, use it to upgrade your application as needed.
- Go to Run > Run Configurations. In the left pane, click the small arrow to the left of Gradle Project.
- Right-click ServiceFabricDeployer, and then select Duplicate. Enter a new name for this configuration, for example, ServiceFabricUpgrader.
- In the right panel, on the Arguments tab, change -Pconfig='deploy' to -Pconfig='upgrade', and then click Apply.
This process creates and saves a run configuration profile you can use at any time to upgrade your application. It also gets the latest updated application type version from the application manifest file.
The application upgrade takes a few minutes. You can monitor the application upgrade in Service Fabric Explorer.
Migrating old Service Fabric Java applications to be used with Maven
We have recently moved Service Fabric Java libraries from Service Fabric Java SDK to Maven repository. While the new applications you generate using Eclipse, will generate latest updated projects (which will be able to work with Maven), you can update your existing Service Fabric stateless or actor Java applications, which were using the Service Fabric Java SDK earlier, to use the Service Fabric Java dependencies from Maven. Please follow the steps mentioned here to ensure your older application works with Maven.
