동적 환경에서 JAR의 매니페스트 파일에 액세스하는 방법은 무엇입니까?

Enumeration<URL> resources = getClass().getClassLoader()
    .getResources("META-INF/MANIFEST.MF");
while (resources.hasMoreElements()) {
    try {
        Manifest manifest = new Manifest(resources.nextElement().openStream());
        // Check if it's the target manifest and perform necessary actions.
    } catch (IOException E) {
        // Handle exception.
    }
}

URLClassLoader cl = (URLClassLoader) getClass().getClassLoader();
try {
    URL url = cl.findResource("META-INF/MANIFEST.MF");
    Manifest manifest = new Manifest(url.openStream());
    // Use the manifest.
} catch (IOException E) {
    // Handle exception.
}
