我的项目数据库没有可用的连接

在执行

$ ./propel model:build --verbose
Processing: schema.xml
  1 tables processed successfully
1 tables found in 1 schema files.
Generating PHP files...
Datamodel: ./schema.xml
 - Database: myproject
  + Table: resource
        -> (unchanged) /Base/Resource.php
        -> (unchanged) /Map/ResourceTableMap.php
        -> (unchanged) /Base/ResourceQuery.php
        -> (exists) Resource.php
        -> (exists) ResourceQuery.php
                (no change)
Object model generation complete - All files already up to date
$ ./propel sql:build --verbose
Processing: schema.xml
  1 tables processed successfully
1 tables found in 1 schema files.
$ ./propel sql:insert --verbose
No connection available for myproject database
$

输出为:

No connection available for myproject database

以下是我感兴趣的3个文件:

的build . properties

runtime-conf.xml

schema.xml

我错过了什么?

谢谢。
