在根项目gradle中找不到任务“安装”

Question

我正在尝试使用Maven插件将我的Gradle项目转换为Maven。我遵循这个SO链接，但当我运行Gradle安装命令时，我得到了以下错误

C:\Users\>gradle install

FAILURE: Build failed with an exception.

* What went wrong:
Task 'install' not found in root project .

* Try:
Run gradle tasks to get a list of available tasks. Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log outpu

* Get more help at https://help.gradle.org

BUILD FAILED in 0s

当我执行gradle-tasks时，它没有显示安装。在这种情况下该怎么办？

Answer 1

你可能是指gradle init，如https://docs.gradle.org/current/userguide/build_init_plugin.html?

如果将install任务应用到您的构建中，而您没有这样做，maven插件会添加该任务。它会将构建的人工制品安装到本地maven存储库中。在你的情况下，这不是你想要的。无论如何，我建议使用maven publish插件，而不是maven插件。

Answer 2

如果添加apply插件：'maven'则gradle安装将创建一个POM。

格雷德尔的剧本就是这样。

buildscript {
     repositories {
         maven { url "http://repo.spring.io/snapshot" }
         maven { url "http://repo.spring.io/milestone" }
         maven { url "https://repo1.maven.org/maven2/" }
         mavenLocal()
        mavenCentral()

    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:2.0.5.RELEASE")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'maven'
apply plugin: "org.springframework.boot"
apply plugin: 'io.spring.dependency-management'
jar {
    baseName = 'Angular-Boot-Rest'
    version =  '0.1.0'
}

repositories {
    mavenLocal()
    mavenCentral()
    maven { url "http://repo.spring.io/libs-release" }
}


tasks.withType(Copy) {
    eachFile { println it.file }
}
jar {
    enabled = true
}
dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
    testCompile("junit:junit")
} 

task stage(dependsOn: ['clean','build','jar', 'installApp']){}

POM就是这样创建的。
