Gradle 构建失败

Question

我正在使用 https://spring.io/guides/gs/producing-web-service/#initial 上的教程来尝试生成 SOAP Web 服务。我正在使用 Gradle 来管理我的依赖项。

我有一个 .xsd 文件，它指定了我希望 gradle 创建的某些类。

但是，当我尝试运行在 eclipse 中的 build.gradle 文件上构建 gradle 时，出现以下错误：

FAILURE: Build failed with an exception.

* Where:
Build file 'C:\Users\zekucukkose\workspace2\gs-producing-web-service-initial\build.gradle' 
line: 32

* What went wrong:
A problem occurred evaluating root project 'gs-producing-web-service-initial'.

> Could not find method jaxb() for arguments [com.sun.xml.bind:jaxb-xjc:2.2.4-1]
 on root project 'gs-producing-web-service-initial'.

第 27 行到第 34 行如下：

27 dependencies {
28    compile("org.springframework.boot:spring-boot-starter-web")
29        compile("org.springframework.boot:spring-boot-starter-ws")
30    testCompile("org.springframework.boot:spring-boot-starter-test")
31    compile("wsdl4j:wsdl4j:1.6.1")
32    jaxb("com.sun.xml.bind:jaxb-xjc:2.2.4-1")
33    compile(files(genJaxb.classesDir).builtBy(genJaxb))
34 }

据我所知，

jaxb 用于生成实际的类。

如果有人能提供帮助，我将不胜感激。谢谢

这是整个脚本：

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.2.7.RELEASE")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'

jar {
    baseName = 'gs-producing-web-service'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
        compile("org.springframework.boot:spring-boot-starter-ws")
    testCompile("org.springframework.boot:spring-boot-starter-test")
    compile("wsdl4j:wsdl4j:1.6.1")
    jaxb("com.sun.xml.bind:jaxb-xjc:2.2.4-1")
    compile(files(genJaxb.classesDir).builtBy(genJaxb))
}

task wrapper(type: Wrapper) {
    gradleVersion = '2.3'
}

task genJaxb {
    ext.sourcesDir = "${buildDir}/generated-sources/jaxb"
    ext.classesDir = "${buildDir}/classes/jaxb"
    ext.schema = "src/main/resources/countries.xsd"

    outputs.dir classesDir

    doLast() {
        project.ant {
            taskdef name: "xjc", classname: "com.sun.tools.xjc.XJCTask",
                    classpath: configurations.jaxb.asPath
            mkdir(dir: sourcesDir)
            mkdir(dir: classesDir)

            xjc(destdir: sourcesDir, schema: schema) {
                arg(value: "-wsdl")
                produces(dir: sourcesDir, includes: "**/*.java")
            }

            javac(destdir: classesDir, source: 1.6, target: 1.6, debug: true,
                    debugLevel: "lines,vars,source",
                    classpath: configurations.jaxb.asPath) {
                src(path: sourcesDir)
                include(name: "**/*.java")
                include(name: "*.java")
            }

            copy(todir: classesDir) {
                fileset(dir: sourcesDir, erroronmissingdir: false) {
                    exclude(name: "**/*.java")
                }
            }
        }
    }
}

configurations {
    jaxb
}

jar {
    baseName = 'gs-producing-web-service'
    version =  '0.1.0'
    from genJaxb.classesDir
}

Answer 1

您需要添加 jaxb 作为配置。这样：

configurations {
   jaxb
}

能否请您提供整个脚本？还是项目资源？

Answer 2

将 task genJaxb 移到 dependencies 部分之前。
