【问题描述】：

在我们的项目中，我们使用 gradle 从 wsdl 文件生成 pojo 类。它看起来像这样（重要的部分）：

dependencies {
    compile project(':util')

    compile ("org.apache.cxf:cxf-rt-frontend-jaxws:$apachecxfVersion") {
        exclude group: 'asm'
    }
    compile "org.apache.cxf:cxf-rt-transports-http:$apachecxfVersion"
    compile "org.apache.cxf:cxf-rt-transports-http-jetty:$apachecxfVersion"
    compile "org.apache.cxf:cxf-tools-common:$apachecxfVersion"

    wsgen "org.apache.cxf:cxf-tools-wsdlto-core:$apachecxfVersion"
    wsgen "org.apache.cxf:cxf-tools-wsdlto-frontend-jaxws:$apachecxfVersion"
    wsgen "org.apache.cxf:cxf-tools-wsdlto-databinding-jaxb:$apachecxfVersion"

    jaxb "com.sun.xml.bind:jaxb-xjc:$jaxbVersion"
    jaxb "com.sun.xml.bind:jaxb-impl:$jaxbVersion"
    jaxb "javax.xml.bind:jaxb-api:$jaxbVersion"
}

tasks.create(name: "gen_wsbindings") {
    compileJava.dependsOn xjc
    ext.genDirName = "$buildDir/gen.wsdls.src"

    inputs.dir new File(srcDir)
    outputs.dir new File(ext.genDirName)

    doFirst {
        new File(ext.genDirName).mkdirs()
    }

    doLast {
        fileTree(dir: srcDir + "/wsdl", include: "**/*.wsdl", exclude: "xxx.wsdl").each { def wsdlFile ->
            println "compiling WSDL " + wsdlFile.name
            javaexec {
                main = 'org.apache.cxf.tools.wsdlto.WSDLToJava'
                classpath = configurations.wsgen
                args '-fe', 'jaxws',
                        '-db', 'jaxb',
                        '-xjc-extension',
                        '-asyncMethods',
                        '-b', srcDir + '/jaxb/jaxws-binding.xml',
                        '-b', srcDir + '/jaxb/jxb-binding.xml',
                        '-impl', '-server', '-client',
                        '-validate',
                        '-autoNameResolution',
                        '-d', ext.genDirName,
                        '-wsdlLocation', 'classpath:wsdl/' + wsdlFile.name,
                        wsdlFile
            }
        }
    }
}

我尝试将'-xjc-XhashCode', '-xjc-Xequals' 插入到wsdlToJava 进程的args 中，但我收到此错误消息：WSDLToJava Error: XJC reported 'BadCommandLineException' for -xjc argument:-extension -extension -XhashCode。

我需要添加一些依赖项吗？谢谢

【问题讨论】：

我不了解 gradle，但对于 Maven jaxb/cxf 插件，它需要对 <groupId>org.jvnet.jaxb2_commons</groupId><artifactId>jaxb2-basics</artifactId> 的额外依赖才能使用 -XhashCode -Xequals 和其他参数。同样对于cxf-codegen-plugin，向 XJC 传递额外的参数看起来像<extraarg>-xjc-Xequals</extraarg>。仍然是关于 Maven 插件，也许你可以检查一下 gradle 对应物是什么......
