maven-jaxb2-plugin VS jaxb2-maven-plugin for multiple schemas
提问by Tinou
I have multiple xsd schemas that I want to unmarshall into different packages under the samefolder target/generated-sources/xjc. I tried both plugins and both seem to work fine with these 2 configurations but in case of maven-jaxb2-plugin the eclipse plugin keeps generating classes indefinitely (because of the forceRegenerate= true) but if I don't specify forceRegenerate it won't generate the second and third set of classes at all when I run mvn clean packageAre there any issues with my configuration?
我有多个 xsd 模式，我想将它们解组到同一文件夹下的不同包中target/generated-sources/xjc。我尝试了这两个插件，并且这两个配置似乎都可以正常工作，但是在 maven-jaxb2-plugin 的情况下，eclipse 插件会无限期地生成类（因为forceRegenerate= true）但是如果我不指定 forceRegenerate 它不会生成运行时mvn clean package根本没有第二组和第三组类我的配置有任何问题吗？

General advice: specify your packages in bindings.xjbrather than in different executions with individual generatePackages.
一般建议：bindings.xjb在单个generatePackages中而不是在不同的执行中指定您的包。
<jxb:bindings schemaLocation="common1.xsd" node="/xsd:schema">
<jxb:schemaBindings>
<jxb:package name="mypackage.commonclasses"/>
</jxb:schemaBindings>
</jxb:bindings>
generatePackagedoes not really work well with multiple schemas.
generatePackage不适用于多个模式。
And please file a bug in
并请提交一个错误

citing the problem with the multiple schemas and Eclipse. I'll take a look into it.
引用多个模式和 Eclipse 的问题。我会研究一下。
