oracle使用时POM is missing

[wishtoday666]

使用插件按oracle生成代码，

<plugin>
....
<dependencies>
                    <dependency>
                        <groupId>com.oracle</groupId>
                        <artifactId>ojdbc6</artifactId>
                        <version>12.1.0.2.0</version>
                        <scope>runtime</scope>
                    </dependency>
                </dependencies>
</plugin>
