Maven无法使用嵌套模式生成JAXB类

我试图让Maven使用嵌套的xml架构生成JAXB绑定:schema A导入架构B.架构B导入架构C.

如果模式A中的对象引用模式B中不依赖于模式C对象的对象,那么一切都会很好地构建。如果模式B中的对象引用模式C中的对象,则它会中断。也就是说,深入一级是有效的。深入两点不会。

一旦我在模式A中添加一个引用模式B中对象的对象,模式B中的对象又引用了模式C中的对象,我得到一个org.xml.sax.SAXParseException:rc-resolve:无法解析名称'schemaB:objectInSchemaB'到(n)'类型定义'组件。

如果省略顶级模式A,我也可以成功构建,并从编译模式B导入模式C开始。再次,问题似乎是嵌套导入的深度不止一个。

我被困住了!

JAXB版本:

检测到JAXB API版本[2.2]。 pluginArtifacts:[org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:maven-plugin:0.9.0:,org.jvnet.jaxb2.maven2:maven-jaxb2-plugin-core:jar:0.9.0:compile, com.sun.org.apache.xml.internal:resolver:jar:20050927:compile,org.sonatype.plexus:plexus-build-api:jar:0.0.7:compile,junit:junit:jar:4.8.1: compile,org.codehaus.plexus:plexus-utils:jar:1.5.15:compile,org.jvnet.jaxb2.maven2:maven-jaxb22-plugin:jar:0.9.0:compile,javax.xml.bind:jaxb- api:jar:2.2.7:compile,com.sun.xml.bind:jaxb-impl:jar:2.2.7:compile,com.sun.xml.bind:jaxb-core:jar:2.2.7:compile, com.sun.istack:istack-commons-runtime:jar:2.16:compile,com.sun.xml.fastinfoset:FastInfoset:jar:1.2.12:compile,javax.xml.bind:jsr173_api:jar:1.0:compile, com.sun.xml.bind:jaxb-xjc:jar:2.2.7:compile,org.apache.maven.plugin-tools:maven-plugin-annotations:jar:3.2:compile] specVersion要求:2.2

下面的“架构A”。如果我注释掉baseSystemConfig对象,那么架构就会编译。

1 个答案:

答案 0 :(得分:1)

我找到了原因:我在嵌套模式中指向了一个元素而不是一个complexType(&#39;一个类型&#39;正如编译错误所说的那样)。这导致编译失败。我需要使用ref =而不是type =,或者更改架构B定义。

所以问题最初看起来太明显了。感谢Xstian确认否则它应该一直在工作。这让我找到了找到它的正确途径。
