 If you run `jarsigner` behind a proxy, pass the standard JVM proxy system properties with `-J`:
- ```bash
- jarsigner   -keystore NONE -storetype AzureKeyVault \
-             -signedjar signerjar.jar ${PARAM_YOUR_JAR_FILE_PATH} "${CERT_NAME}" \
-             -verbose  -storepass "" \

 `http.nonProxyHosts` may be needed for local or managed identity endpoints, such as `169.254.169.254`,
 that should bypass the proxy.
