Creating a JAR file with Eclipse
These instructions are only a guide for creating a JAR based on a single .java file.
Take it as an introduction.
The following steps may vary depending on the Eclipse version.
- Choose the Java file from Project Explorer or Navigator view.
- Right-click (a contextual menu will be shown) and choose "export".
- Choose Java -> JAR file.
- Select the destination folder, for example C:\openkm-dev\jar\your-class.jar.
- Click Next.
- Click Next.
- Optional step. If your Java class implements "public static void main(String[] args)", then you must choose your Java class as the entry point.
- Click Finish.
