Gradle任务来编译Java和Groovy源

Question

我们正在使用gradle启动一个新项目（我以前的所有项目都在Maven上），这是我使用gradle的初次经验，下面是我的build.gradle文件，并尝试使用任务compile java和groovy源代码

buildscript {
    ext {
        springBootVersion = '1.5.2.RELEASE'
        springVersion = '4.3.7.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'groovy'
apply plugin: 'org.springframework.boot'

version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
    mavenCentral()
}


task compile(type: GroovyCompile) {
    //source = fileTree(dir: 'src', include: '**/*.java')
    sourceSets {
        main {
            java { srcDirs = [] }    // no source dirs for the java compiler
            groovy { srcDir "src" }  // compile everything in src/ with groovy
        }
    }
    destinationDir = file('build/classes/main')

    classpath = files('build/classes/main')
}

dependencies {
    compile "org.codehaus.groovy:groovy-all:2.4.10"
    compile('org.springframework.boot:spring-boot-starter-actuator:${springBootVersion}')
    compile('org.springframework.boot:spring-boot-actuator-docs:${springBootVersion}')
    compile('org.springframework.boot:spring-boot-starter-groovy-templates:${springBootVersion}')
    compile('org.springframework.boot:spring-boot-starter-jdbc:${springBootVersion}')
    compile('org.springframework.boot:spring-boot-starter-jersey:${springBootVersion}')
    compile('org.springframework.boot:spring-boot-starter-security:${springBootVersion}')
    compile('org.springframework.boot:spring-boot-starter-web:${springBootVersion}')
    compile('org.springframework:spring-webmvc:${springVersion}')
    compile "com.microsoft:sqljdbc4:4.0"
    testCompile('org.springframework.boot:spring-boot-starter-test:${springBootVersion}')
}

当我运行gradle compile命令时，看到:compile NO-SOURCE并且build\\classes\\main没有编译的类

有人可以帮我执行gradle任务来编译java和groovy源代码吗？

Groovy插件的Gradle文档描述了默认布局，如下所示。 如果可以选择这样做，则无需自定义编译任务。

src/main/java       Production Java source
src/main/resources  Production resources
src/main/groovy     Production Groovy sources. May also contain Java sources for joint compilation.
src/test/java       Test Java source
src/test/resources  Test resources
src/test/groovy     Test Groovy sources. May also contain Java sources for joint compilation.
