Step 2: Preparing a DIS Application Development Environment

Before developing DIS applications, prepare an application development environment, and then obtain a software development kit (SDK) and sample project and import them to the development environment.

Prerequisites

  • JDK 1.8 or later has been installed.
  • Eclipse has been installed.

Procedure

  1. Configure a JDK using Eclipse.

    1. Start Eclipse and choose Window > Preferences. The Preferences dialog box is displayed.
    2. In the navigation tree, choose Java. On the Java page, configure general settings for Java development and then click OK.

    3. In the navigation tree, choose Java > Installed JREs.
      • Ensure that configured JDK environmental variables are displayed on the Installed JREs page. Then go to 1.c.i.
      • To configure different variables for different versions of JDK, perform 1.c.ii to 1.c.iv.

  2. Download resource packages.

    Download the DIS Java SDK from https://github.com/huaweicloud/huaweicloud-sdk-java-dis.

    Obtain huaweicloud-sdk-dis-java-X.X.X.zip from the DIS SDK. The package contains the demo package of the sample project.

  3. Import the Eclipse project.

    1. Start Eclipse. Choose File > Import. The Import dialog box is displayed.
    1. Choose Maven > Existing Maven Projects, and click Next. The Import dialog box is displayed.
    2. Click Browse and select a save location for the dis-sdk-demo sample project. In the Projects area, select a sample project.
