Gradle：构建文件不应该包含声明

Question

我有一个由buildSrc/build.gradle和一个项目级build.gradle组成的gradle构建项目。 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，当项目级别的build.gradle尝试实例化由buildSrc/build.gradle引入的类的实例时，构建失败。错误是：

无法打开构建文件的no_buildscript类缓存〜/ git/project/build.gradle - 构建文件〜/ git/project/build.gradle不应该包含一个包语句。

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

我已经尝试将bacon-test-utilities软件包导入到项目级构建中，并从“def dashUpdater”行中的类中删除软件包名称。这给了我相同的构建错误。

任何人都可以帮助我理解为了访问由项目级构建中的buildSrc/gradle.build引入的类，还需要做些什么？

谢谢

这里是我的buildSrc /的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}/" 
} 

} 

这里是我的项目级的build.gradle的相关位：

// 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运行任务的堆栈跟踪输出：

Answer 1

一位同事，我孤立了这个问题，导致我的gradle生成失败，并显示“build.gradle不应该包含包语句”错误。包含依赖项的jar文件包含.class和.groovy文件。当我们重新编译jar包含.class文件时，gradle构建运行时没有错误，并且能够从（麻烦的！）依赖项实例化一个类。

我还通过删除buildSrc/build.gradle简化了我的构建结构。它不再需要，因为该目录中没有源代码。为了引入项目级build.gradle中所需的（麻烦！）依赖项，我使用了一个buildScript块。

谢谢Peter Niederwieser阅读并回答问题！

下面是最终构建脚本中的相关内容：

// vim:ft=groovy 

import com.drillinginfo.global.test.utils.DIGSauceLabsUpdater 

apply plugin: 'base' 
apply plugin: 'java' 
apply plugin: 'eclipse' 
apply plugin: 'maven' 
apply plugin: 'groovy' 

// 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" 

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

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

buildscript { 
    repositories { 
     maven { 
      url "${project.mavenPublicUrl}/" 
     } 
    } 
    dependencies { 
     classpath group: 'com.drillinginfo.global', name: 'bacon-test-utilities', version: '0.0.1+17' 
    } 
} 

/automated acceptance tasks 
// -------------------------- 
// define a TestListener implementation to report test results to Sauce Labs 
def dashUpdater = new DIGSauceLabsUpdater() 

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

    gradle.addListener(dashUpdater) 
} 

Answer 2

我遇到这个问题，在build.gradle如下：

buildscript { 
    dependencies { 
    classpath fileTree(
      dir: "some/directory", 
      include: '**/*.jar') 
    } 
} 

some/directory有源罐子所以修正为：

buildscript { 
    dependencies { 
    classpath fileTree(
      dir: "some/directory", 
      include: '**/*.jar', 
      exclude: '**/-sources.jar') 
    } 
}
