如https://developers.google.com/appengine/docs/java/cloud-sql/developers-guide中所述,我需要在 Eclipse 中的“程序参数”文本框的“参数”选项卡上为我的 App Engine 运行配置添加参数
--jvm_flag=-Drdbms.server=local
--jvm_flag=-Drdbms.driver=com.mysql.jdbc.Driver
--jvm_flag=-Drdbms.url=jdbc:mysql://localhost:3306/yourdatabase?user=username&password=password
但我总是遇到快速错误:
Usage: <dev-appserver> [options] <app directory>
Options:
--help, -h Show this help message and exit.
--server=SERVER The server to use to determine the latest
-s SERVER SDK version.
--address=ADDRESS The address of the interface on the local machine
-a ADDRESS to bind to (or 0.0.0.0 for all interfaces).
--port=PORT The port number to bind to on the local machine.
-p PORT
--sdk_root=DIR Overrides where the SDK is located.
--disable_update_check Disable the check for newer SDK versions.
--generated_dir=DIR Set the directory where generated files are created.
--jvm_flag=FLAG Pass FLAG as a JVM argument. May be repeated to
supply multiple flags.
我究竟做错了什么?
