Question

我正在使用maven 3.1.0。

尝试通过cmd构建时出错。

[ERROR] Failed to execute goal org.jvnet.jaxb1.maven2:maven-jaxb1-plugin:1.0-rc9:generate (default) on project Myproject: Execution default of goal org.jvnet.jaxb1.maven2:maven-jaxb1-plugin:1.0-rc9:generate failed: A required class was missing while executing org.jvnet.jaxb1.maven2:maven-jaxb1-plugin:1.0-rc9:generate: com/sun/msv/grammar/Grammar

我通过命令行调用了maven。

我的POM.xml如下所示：

<plugin>
    <groupId>org.jvnet.jaxb1.maven2</groupId>
    <artifactId>maven-jaxb1-plugin</artifactId>
    <version>1.0-rc9</version>
    <executions>
        <execution>
            <goals>
               <goal> generate  </goal>
            </goals>
     </execution>
    </executions>
<configuration>
<generatePackage>jaxb1/package</generatePackage>
</configuration>

免责声明：我是这个插件的作者，很久以前写过。

正如@skaffman所说，JAXB 1很古老，所以maven-jaxb1-plugin目前尚未得到积极支持。请改用maven-jaxb2-plugin。

如果您有特殊原因被迫使用maven-jaxb1-plugin，您可能需要自行修复。我可以将代码移动到GitHub并接受拉取请求。这是我现在能做的最好的事情。
