问题


I am trying to create a maven project with DataNucleus and MySQL. However, when i try to build and mvn datanucleus:schema-create the project, I get a failure. I can't figure out why.

Here is the persistence.xml class, and it is present in the classes/META-INF folder of the built project:

<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
        http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
    version="2.0">

    <!-- JDO tutorial "unit" -->
    <persistence-unit name="Tutorial">
        <class>hello.Counter</class>
        <exclude-unlisted-classes>true</exclude-unlisted-classes>
        <properties>
            <property name="javax.jdo.option.ConnectionURL" value="jdbc:mysql://localhost/glu" />
            <property name="javax.jdo.option.ConnectionDriverName"
                value="com.mysql.jdbc.Driver" />
            <property name="javax.jdo.option.ConnectionUserName" value="root" />
            <property name="javax.jdo.option.ConnectionPassword" value="root" />

            <property name="datanucleus.schema.autoCreateAll" value="true" />
            <property name="datanucleus.schema.validateTables" value="true" />
            <property name="datanucleus.schema.validateConstraints"
                value="true" />
            <property name="javax.jdo.PersistenceManagerFactoryClass"
                value="org.datanucleus.api.jdo.JDOPersistenceManagerFactory" />
        </properties>
    </persistence-unit>
</persistence>

Here is the pom.xml i am trying to use.

The error that I get is:

UPD If i remove the <scope>runtime</scope> restriction from datanucleus-rdbms, I get the following error:

回答1:


The error message Make sure that you have put the relevant DataNucleus store plugin in your CLASSPATH says all you really need to know. The datanucleus-rdbms plugin is NOT in the CLASSPATH ... your scope restriction on runtime
