How to set the java.library.path from Eclipse

To set the java.library.path from Eclipse, you can use the following steps:

1. Open your project in Eclipse.
2. Right-click on the project and select "Properties" from the context menu.
3. In the "Properties" window, select "Java Build Path" from the left-hand side.
4. Click on the "Libraries" tab.
5. Click on the "Add External JARs" button.
6. Navigate to the directory where the native library files are located, select them, and click "Open".

This will add the native library files to the project's classpath, and the java.library.path system property will be set to the directory where the native library files are located.

Alternatively, you can set the java.library.path system property directly from the command line when starting the Java application. To do this, use the -D option to set the system property, as follows:

java -Djava.library.path=path/to/library/dir MyApplication

Replace path/to/library/dir with the directory where the native library files are located, and MyApplication with the name of your Java application.

Note that the java.library.path system property specifies a list of directories separated by semicolons (on Windows) or colons (on Linux and macOS), where the Java runtime will search for native libraries. If you have multiple directories where you want to search for native libraries, you can specify them all in the java.library.path system property, separated by the appropriate separator for your operating system.
