Grails - Database Reverse Engineer plugin not found

问题

Environment

Grails 2.4.4
PostgreSQL 9.4
JDK 1.7

I've been trying to get this plugin to work. (I'm still a grails newbie, not to mention programming.)

I tried to do everything I can find out there but still get this untimate error message.

This is what I have right not in my config files. (I've tried to change a lot of them, such as Hibernate, plugin version etc, but always end up with that message.)

Thanks in advance.

EDIT 1 So, I changed DbReverseEngineer.groovy under Script folder like this.

mergedConfig.driverClassName = dsConfig.driverClassName ?: 'org.postgresql.Driver'
mergedConfig.password = dsConfig.password ?: ''
mergedConfig.username = dsConfig.username ?: 'postgres'
mergedConfig.url = dsConfig.url ?: 'jdbc:postgresql://localhost:5432/myApp'

And I changed plugin and dependency per Burt's and Emmanuel's advice. And when I run grails db-reverse-engineer command I get this error.

Compilation error: startup failed:
Compile error during compilation with javac.

What are those errors mean and how can I get rid of it? Thanks.

回答1:

You've got the same plugin set up twice:

compile 'org.grails.plugins:db-reverse-engineer:4.0.0'
runtime ':db-reverse-engineer:4.0.0'

According to the plugin's page it should be configured as a compile time dependency:

compile "org.grails.plugins:db-reverse-engineer:4.0.0"

The plugin does have the command that's claimed to be missing. You can see it here. So you may need to refresh the dependencies by running:

grails refresh-dependencies
