I found the answer here -

You have to convert your to a PKCS12 certificate to import it with a command similar to the following.

keytool -importkeystore -deststorepass changeit -destkeypass changeit -destkeystore my-keystore.jks -srckeystore cert-and-key.p12 -srcstoretype PKCS12 -srcstorepass cert-and-key-password -alias 1

To convert from PEM to PKCS12 use the following command.

openssl pkcs12 -export -out certificate.pfx -inkey privateKey.key -in certificate.crt -certfile CACert.crt
