Importing custom extensions into the Developer Toolkit environment

You can import custom extensions into a new or existing developer toolkit environment to add custom extensions from another developer toolkit environment or source control repository to help you quickly set up or update the environment.

The process that you need to complete for importing extensions depends on whether you want to import extensions into a new developer toolkit environment that you are planning to set up or into an environment that is already set up:

If you are setting up a developer toolkit environment, you can obtain the extensions to import from Sterling Order Management System Software where you downloaded the development toolkit that you are using to set up the environment or from an external customization package.
- To include extensions from the Sterling Order Management System Software environment, select the option Include customizations when you run the process to download the developer toolkit from the environment.
- To include extensions from an external customization package, add the full path to the extensions.jar package when you are configuring the devtoolkit_setup.properties file as part of setting up the developer toolkit environment. For more information, see Setting up the Integrated Developer Toolkit environment.
For importing into a developer toolkit environment that is set up, complete one or both of the processes in the following procedure.

Procedure

Optional: Import extensions that are packaged within an extensions Java archive (JAR), such as an extensions.jar that is exported from another developer toolkit environment or provided by your SaaS Extensions Support Provider.

The archive can come from any source, but must conform to the required package structure. To ensure that the archive conforms to this structure, ensure that the package is created with the export capability of a developer toolkit environment for the Sterling Order Management System Software. For more information about exporting extensions, see Exporting custom extensions from a developer toolkit environment.
1. In a command-line utility, go to the runtime/bin directory of your developer toolkit environment.
  
  Remember: In case of docker-based developer toolkit, runtime directory is the extracted runtime directory.
2. Run the following command:
  ./sci_ant.sh -f ../devtoolkit/devtoolkit_extensions.xml import -Dpackage=extension_archive_path
  Where extension_archive_path is the full path to the extensions.jar archive that you want to import.
Optional: Import custom extensions from a project that is set up for extension files and that is checked out of your source control repository:
If you want to import from a project, you must manually structure your source code repository project to match the expected project structure. The project must conform to the following structure for you to successfully import the project:
```
<project root directory>
|-- files
| |-- extensions
| | |-- global
| |   |-- <custom extension files>
| |   |-- resources
| |     |-- <custom resource files, such as any custom log4jconfig xml>
| |-- properties
| | |-- customer_overrides.properties
| | |-- <any other allowed overridable property file(s)>
| |-- repository
|   |-- eardata
|      |-- <relative path to any extension directory>
|--src
| |-- <custom source java files in proper package structure>
|--lib
  |--<additional jar files for compiling custom source files>
```
- Include any custom extension files within the files/extensions/global directory.
- Include any custom Java source files in the correct package in the src directory.
- Include the custom JAR files that are and required for compilation of custom source files directly within the lib directory and not within any sub-directory.
1. In a command-line utility, go to the bin directory of your target developer toolkit environment.
2. Run the following command to deploy the extensions directly from the project into your developer toolkit environment:
  ./sci_ant.sh -f ../devtoolkit/devtoolkit_extensions.xml importfromproject -Dprojectdir=project_path
  Where project_path is the full path to the project root directory.
  When the command runs, custom source files are compiled into a custom_impl.jar archive and copied to the <runtime>/jar/custom_jars/1_0 directory along with other dependent Java archives that are in the lib directory. These copied archives are added to all class paths in the runtime component.
  
  If this command fails, such as from compilation errors, the project directory not conforming to the structure specified, or other error, deploy the extensions manually to the runtime component.
