【问题描述】：

我有这个gradle.build

apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'maven-publish'
apply from: ext.gradleDir + '/common.gradle'
apply from: ext.gradleDir +'/base.gradle'
apply from: ext.gradleDir + '/integration_test.gradle'

sourceCompatibility = 1.8
targetCompatibility = 1.8
version = '1.0'

project.archivesBaseName = 'client-services-lib'
uploadArchives.repositories.mavenDeployer.pom.groupId="com.waze.automation"


dependencies 
    compile('com.waze.automation:common:1.0.58')

    compile('com.sun.jersey:jersey-bundle:1.19')
    compile('com.sun.jersey:jersey-json:1.19')

    testCompile('org.hamcrest:hamcrest-all:1.3')
    testCompile('org.mockito:mockito-all:1.9.5')



war 
    from 'src/main' // include source files in war

我运行这个

❯ ./gradlew build -i                                                                                                                                                                                                                      [12:40:40]

还有这个base.gradle

    if (value == "false" || value == "no" || value == "0" || value == "") 
            return false
    

    throw new IllegalArgumentException("Invalid value of flag property \"$name\": \"$value\", must be one of true, false, yes, no, 0, 1 or empty")

我不明白为什么上面写着Cannot add task ':library-services:wrapper' as a task with that name already exists.

我看不到我的 gradle.build 甚至尝试添加 "wrapping" 任务

我的 gradle.build 不会尝试添加任务“包装器” 它没有出现在 base.gradle' line: 28

【问题讨论】：

你能显示 library-services/build.gradle 吗？

已添加。但我的 gradle.build 没有尝试添加任务“包装器”，并且它没有出现在 base.gradle' 行：28

【参考方案1】：

您是否将 base.gradle 应用于所有子项目？您是否也将其应用于您的根项目？

gradle 中的 wrapper 任务只添加到根项目中，不添加到子项目中。如果您将 base.gradle 应用于所有项目，那将是您的问题的原因。

【讨论】：

你在哪里看到我添加了“android”插件？

我很抱歉。我正在回答一系列 android-gradle 问题，然后在我的脑海中填写。重新尝试回答。
