I\'m trying to read my META-INF/MANIFEST.MF file from my Spring Boot web app (contained in a jar file).

I\'m trying the following code:

I have it exploiting Spring's resource resolution:

@Service
public class ManifestService {

    protected String ciBuild;

    public String getCiBuild() { return ciBuild; }

    @Value("${manifest.basename:/META-INF/MANIFEST.MF}")
    protected void setManifestBasename(Resource resource) {
        if (!resource.exists()) return;
        try (final InputStream stream = resource.getInputStream()) {
            final Manifest manifest = new Manifest(stream);
            ciBuild = manifest.getMainAttributes().getValue("CI-Build");
        }
        catch (IOException e) {
            throw new RuntimeException(e);
        }
    }

}

Here we're getting CI-Build, and you can easily extend the example to load other attributes.
