hibernate3-maven-plugin 3.0 在 Eclipse 中使用 m2eclipse 运行良好，但使用独立 maven 失败

Question

我将 Eclipse Indigo 与 M2Eclipse 1.0.200.20111228-1245 一起使用，我想使用 hibernate3-maven-plugin 3.0 版从我的 Hibernate 配置文件和映射文件生成数据库模式。这是我的 pom.xml 中的插件 xml sn-p。

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>hibernate3-maven-plugin</artifactId>
    <version>3.0</version>
    <executions>
        <execution>
            <id>create-schema</id>
            <phase>process-test-resources</phase>
            <goals>
                <goal>hbm2ddl</goal>
            </goals>
            <configuration>
                <components>
                    <component>
                        <name>hbm2ddl</name>
                        <implementation>configuration</implementation>
                    </component>
                </components>
                <hibernatetool destdir="${project.basedir}">
                    <classpath>
                        <path
                            location="${project.basedir}/src/main/resources/mappings/" />
                    </classpath>
                    <configuration
                        configurationfile="${project.basedir}/src/test/resources/hibernate.cfg.xml" />
                    <hbm2ddl create="true" export="false"
                        drop="true" outputfilename="schema.sql"
                        format="true" console="false" />
                </hibernatetool>
            </configuration>
        </execution>
    </executions>
</plugin>

通过上述配置，我可以使用 m2eclipse（嵌入式 maven 3.0.2）在 Eclipse 中运行“Maven 构建”，并且目标“process-test-resources”就好了。但是当我尝试使用独立的 maven (3.0.4) 运行时，我遇到了这样的异常

如果有任何帮助，这里是hibernate3-maven-plugin 3.0 版的工作配置。它正在启动hbm2java（您的问题是针对hbm2ddl），但无论如何在我看来它很有用，尤其是在没有其他人回答的情况下（还）。

<configuration>
    <hibernatetool>
        <classpath>
            <path location="${project.build.testOutputDirectory}" />
        </classpath>
        <jdbcconfiguration
            propertyfile="${basedir}/jpa-reveng/hibernate.properties"
            revengfile="${basedir}/jpa-reveng/hibernate.reveng.xml"
            reversestrategy="com.package.MyReverseEngineeringStrategy" />
        <hbm2java jdk5="true" ejb3="true"
            destdir="${project.build.sourceDirectory}" />
    </hibernatetool>
</configuration>
