如何使用Gradle。Java和Groovy在一起？

Question

我试图在Intellij13中使用一个Gradle项目，但我经常遇到这样的问题：

null

null

apply plugin: 'java'
apply plugin: 'groovy'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'
apply plugin: 'jacoco'
apply plugin: 'war'


buildscript {
    repositories {
        maven { url "http://repo.spring.io/libs-snapshot" }
        mavenLocal()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.0.0.RC4")
    }
}

jar {
    baseName = 'my-app'
    version = '0.1.0'
}

repositories {
    mavenCentral()
    maven { url "http://repo.spring.io/libs-snapshot" }
}

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
    compile("org.springframework.boot:spring-boot-starter-data-jpa:1.0.0.RC4")
    compile("org.springframework:spring-orm:4.0.0.RC1")
    compile("org.hibernate:hibernate-entitymanager:4.2.1.Final")
    compile("com.h2database:h2:1.3.172")
    compile("joda-time:joda-time:2.3")
    compile("org.thymeleaf:thymeleaf-spring4")
    compile("org.codehaus.groovy.modules.http-builder:http-builder:0.7.1")
    compile ('org.codehaus.groovy:groovy-all:2.2.1')

    testCompile('org.spockframework:spock-core:0.7-groovy-2.0') {
        exclude group: 'org.codehaus.groovy', module: 'groovy-all'
    }
    testCompile('org.codehaus.groovy.modules.http-builder:http-builder:0.7+')
    testCompile("junit:junit")
}

jacocoTestReport {
  <!-- not sure this is right  -->
    group = "Reporting"
    description = "Generate Jacoco coverage reports after running tests."
}

task wrapper(type: Wrapper) {
    gradleVersion = '1.11'
}

下面是我在运行“Gradle clean build”时得到的一个构建错误：

...src/main/java/com/product/service/FileDownloadService.java:24:  cannot find symbol 
symbol  : class FileDownload 
location: class com.product.service.FileDownloadService

private FileDownload fileDownload;

如果我把所有东西都变成Java，那么我就不会得到任何编译或执行错误。

尝试向文件“build.gradle”追加下一行

sourceSets {
      main {
        java { srcDirs = [] }    // no source dirs for the java compiler
        groovy { srcDir "src" }  // compile everything in src/ with groovy
       }
    }

请原谅我英语不好。我希望这能帮助你解决问题。
