无法将任务“X”添加为具有该名称的任务已存在

Question

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')
    compile group:  'org.codehaus.jackson', name:'jackson-jaxrs', version: '1.1.1'

    compile('com.google.guava:guava:18.0')

    testCompile group: 'junit', name: 'junit', version: '4.11'
    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

project.ext.flag = { String name ->
    if (!project.hasProperty(name)) {
            return false
    }

    String value = project.ext[name]
    value = value.toLowerCase()

    if (value == "true" || value == "yes" || value == "1") {
            return true
    }

    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

Answer 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。
