eclipse luna和postgres db 9.4连接

Question

我正试图在eclipse中连接postgres。但是在输入jdbc连接的所有详细信息后，我收到了以下错误：

Database:postgres
url:jdbc:postgresql://localhost:5432/postgres
user name:postgres
pass :postgres

jar文件：D：\ Workspace：postgresql-9.4-1202.jdbc41

Ping failed:
org.postgresql.util.PSQLException: FATAL: password authentication failed for user "postgres"
