Gradle：构建文件不应包含包语句

【问题标题】：Gradle: Build file should not contain a package statementGradle：构建文件不应包含包语句
【发布时间】：2013-05-13 15:29:14
【问题描述】：

我有一个 gradle 构建项目，它由一个 buildSrc/build.gradle 和一个项目级 build.gradle 组成。 buildSrc/build.gradle 编译一个 jar 依赖项，其中包含项目级 build.gradle 需要的类。但是，当项目级 build.gradle 尝试实例化由 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，项目级构建需要由 buildSrc/build.gradle 引入的 bacon-test-utilities 中的 DIGSauceLabsUpdater 类。

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。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 拉入的类？

谢谢，

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 运行任务的堆栈跟踪输出：

【问题讨论】：

  • Gradle 抱怨的是一个包statement（例如package foo.bar）。显然您的构建脚本中有一个，这是不允许的。
  • Gradle 抱怨的“包声明”是一行：
  • package 声明 Gradle 抱怨的行是： def dashUpdater = new com.drillinginfo.global.test.utils.DIGSauceLabsUpdater() 。我不明白为什么它被解释为一个包而不是一个完全限定的类名。对不起，分裂的帖子！我在编辑原始评论时被叫去开会。
  • 这不是包装声明。也许堆栈跟踪 (-s) 有原因？
  • 这就是我感到困惑的原因。如果我删除那行代码，错误就会消失。问题可能是因为我需要在 buildSrc/build.gradle 和项目级 build.gradle 中编译相同的依赖项吗？

标签： gradle build.gradle gradlew


【解决方案1】：

如果遇到此错误：

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

你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。

    【解决方案2】：

    我和一位同事隔离了导致我的 gradle 构建失败并出现“build.gradle 不应包含包语句”错误的问题。包含依赖项的 jar 文件同时具有 .class 和 .groovy 文件。当我们重新编译 jar 以仅包含 .class 文件时，gradle 构建运行没有错误，并且能够从（麻烦！）依赖项中实例化一个类。

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

    感谢 Peter Niederwieser 阅读并回答问题！

    以下是最终构建脚本的相关部分：

    // 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)
}

      【解决方案3】：

      我在build.gradle 中遇到了这个问题：

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

      some/directory 有源 jar，所以修复是：

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