The properties file isn't present on the D:or the set drive. The java file isn't correctly compiled to a JAR file and uploaded to the instance. The properties file doesn't have the info for the user and password key that is to be set following the key on the CredentialResolver.java file. Resolution Depending on the issue and the causes, try one of the following Set the path to the environment variable, 'CREDENTIAL_RESOLVER_FILE' to point to the properties file. Move the properties file to the D: or the drive used in the CredentialsResolver.java file. Compile the JAR file correctly and then upload it to the ServiceNow instance. Update the properties file correctly with the following key for user and password CredentialID.ssh.user=*user* CredentialID.ssh.pswd=password For example: If the credentialID is 123, then 123.ssh.user=user and 123.ssh.pswd=password Once these changes have been incorporated, run the credential test again. This should resolve the credentials correctly.
