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 片段。
<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>
使用上述配置,我可以在 Eclipse 中使用 m2eclipse(嵌入式 maven 3.0.2)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
