Gradle：构建文件不应包含包声明

Question

我有一个 gradle 构建项目，由 buildSrc/build.gradle 和项目级 build.gradle 组成。buildSrc/build.gradle 编译一个 jar 依赖项，其中包含项目级 build.gradle 所需的类。但是，当项目级 build.gradle 尝试实例化 buildSrc/build.gradle 引入的类的实例时，构建会失败。错误是：

无法打开构建文件 ~/git/project/build.gradle 的 no_buildscript 类缓存 - 构建文件 ~/git/project/build.gradle 不应包含包语句。

特别是，项目级构建需要 DIGSauceLabsUpdater 类，该类位于 buildSrc/build.gradle 引入的 bacon-test-utilities 中。

我尝试将 bacon-test-utilities 包导入到项目级构建中，并从“def dashUpdater”行中的类中删除包名称。这给了我同样的构建错误。

谁能帮助我了解我还需要做什么才能访问项目级构建中的 buildSrc/gradle.build 引入的类？

谢谢你，

这是我的 buildSrc/build.gradle 文件：

// vim:ft=groovy
apply plugin: 'base'
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'maven'
apply plugin: 'groovy'


// automated test dependencies
// ---------------------------
dependencies {
def saucerestVersion = "1.0"

compile gradleApi()

// sauce lab's REST client
compile "com.saucelabs.saucerest:saucelabs-saucerest:$saucerestVersion"

// test utilities 
// Note: Needed here for DIGSauceLabsUpdater use in main build.gradle
compile "com.drillinginfo.global:bacon-test-utilities:0.+"
}

// artifacts and maven stuff
// -------------------------
repositories {

    maven {
    url "${project.mavenPublicUrl}/"
}

}

以下是我的项目级 build.gradle 的相关部分：

// vim:ft=groovy
apply plugin: 'base'
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'maven'
apply plugin: 'groovy'

// browser driver extensions for acceptance test tasks
ext.drivers = ["firefox", "chrome", "ie"]


// automated test dependencies
// ---------------------------
dependencies {
    groovy "org.codehaus.groovy:groovy-all:1.8.6"

    def gebVersion = "0.7.2"
    def seleniumVersion = "2.31.0"
    def lazerycodeVersion = "1.1"
    def saucerestVersion = "1.0"

    // spock
    testCompile "org.codehaus.geb:geb-spock:$gebVersion"
    testCompile "org.spockframework:spock-core:0.6-groovy-1.8"

    // gradle plugin for test listener code
    compile files('buildSrc/src/main/lib/gradle-plugins-1.2.jar')

    // test utilities
    testCompile "com.drillinginfo.global:bacon-test-utilities:0.+"

    // Drivers
    drivers.each { driver ->
        testCompile "org.seleniumhq.selenium:selenium-$driver-driver:$seleniumVersion"
    }
}

// automated acceptance tasks
// --------------------------
// define a TestListener implementation to report test results to Sauce Labs
// THE NEXT LINE IS WHERE THE BUILD CHOKES
def dashUpdater = new com.drillinginfo.global.test.utils.DIGSauceLabsUpdater()

// ensure the tests have access to properties passed in on the command line (-D) 
tasks.withType(Test) {

    gradle.addListener(dashUpdater)
}

这是我的 ./gradlew run 任务的堆栈跟踪输出：

如果您遇到此错误：

Build file '...\build.gradle' should not contain a package statement.

您应该检查上面提到的路径并删除build.gradle文件第一行中的包语句。希望有帮助。
