Can't run Grails app with mongodb plugin version 3.0.3

问题

I'm trying to upgrade my mongodb plugin from 2.0.1 to 3.0.3. However I keep getting the following error:

I've tried changing the version of the plugin to 3.0.2 but the error persists.

UPDATE:

I'm on Grails 2.3.11.

I've tried including the plugin with specifying no dependencies and also copy pasting the dependencies from my past configuration which is:

 dependencies {

        runtime "org.mongodb:mongo-java-driver:2.11.4"
        compile "org.mongodb:mongo-java-driver:2.11.4"
        runtime "com.gmongo:gmongo:1.2"

    }

and

 plugins {

        ...

        compile(':mongodb:2.0.1') {
            excludes 'mongo-java-driver', 'gmongo'
        }

回答1:

Update your BuildConfig a bit:

compile ":mongodb:3.0.2"

Don't specify any other mongo related dependencies and don't exclude mongo-java-driver or gmongo. Also, if you are using mongeez plugin then you have to exclude the java driver.

compile (":mongeez:0.2.3") {
    excludes("mongo-java-driver")
}

回答2:

changing dependencies to:

runtime "org.mongodb:mongo-java-driver:2.12.3"

compile "org.mongodb:mongo-java-driver:2.12.3"

works
