Maven Jaxb2插件拋出錯誤“未定義的元素聲明's：schema'”

Question

我正在嘗試使用maven jaxb2 plugin生成類。 但是我收到以下異常：

搜索后，我發現wsdl中的以下2聲明引起了該問題：

<s:element ref="s:schema"/>
<s:any/>

在其中一篇文章中，我發現如果我用下面給定的行來更改上面的兩行，那么插件將生成文件而沒有任何問題：

<s:any  minOccurs="2" maxOccurs="2" />

以下是我正在使用的插件配置：

<plugin>
            <groupId>org.jvnet.jaxb2.maven2</groupId>
            <artifactId>maven-jaxb2-plugin</artifactId>
            <version>0.12.3</version>
            <executions>
                <execution>
                    <goals>
                        <goal>generate</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <schemaLanguage>WSDL</schemaLanguage>
                <generatePackage>com.abc</generatePackage>
                <schemas>
                    <schema>
                        <url>http://someIP/dummywsdl.asmx?wsdl</url>
                    </schema>
                </schemas>
            </configuration>
        </plugin>

是否有其他方法可以解決此問題而無需更改WSDL，因為這是客戶端WSDL，並且我不希望通過上述更改將其存儲在本地。

您的架構似乎無效。 所以不，除非您修復錯誤，否則XJC不會編譯它。

解決方法是，可以創建架構的本地副本並修復此副本。 您可以創建一個目錄文件，該文件將“全局” URL http://someIP/dummywsdl.asmx?wsdl`` into your local重寫” http://someIP/dummywsdl.asmx?wsdl`` into your local dummywsdl.asmx_wsdl`中：

REWRITE_SYSTEM "http://someIP/dummywsdl.asmx?wsdl" "dummywsdl.asmx_wsdl"

有關更多信息，請參見使用目錄 。
