使用Gradle将jar发布到MavenLocal

问题描述：

我正在使用Gradle使用多个Eclipse项目来管理产品的构建。

I'm using Gradle to manage the build of a product using multiple eclipse projects.

其中一些项目使用了中央存储库中不可用的jar文件（例如MavenCentral）。

Several of those projects use jar files that are not available from a central repository (like MavenCentral).

我想创建一个Eclipse项目，将这些jar文件放入其中，并建立一个build.gradle，将这些jar文件放入mavenLocal使用我指定的groupId，artifactId和版本。

I'd like to have an eclipse project that I just place those jars into, and a build.gradle that will place those jar files into mavenLocal using the groupId, artifactId and version that I specify.

这样，我可以将 mavenLocal（）添加到其他项目并指定依赖项。

This way I can just add mavenLocal() to other projects and specify the dependency.

我有以下 build.gradle ：

apply plugin: 'maven-publish'

publishing {
    publications {
        maven(MavenPublication) {
            groupId 'myGroupId'
            artifactId 'myArtifact'
            version '1.2.3'
            from  <how to reference jar>
        }
    }
}

我尝试了 file（'myJar.jar'），但是不接受。似乎Gradle想要一个from值的工件，但是我似乎找不到如何将预构建的jar文件指定为该工件。

I've tried file('myJar.jar'), but that isn't accepted. It appears that Gradle wants an artifact for the from value, but I can't seem to find how to specify a prebuilt jar file as that artifact.

似乎应该

答

当前，'from'只能接受 components.java 和 components.web 。要包含一个罐子，请使用'artifact'，例如：

Currently, 'from' can only accept components.java and components.web. To include a jar, use 'artifact', for example:

publishing {
    publications {
        maven(MavenPublication) {
            groupId 'myGroupId'
            artifactId 'myArtifact'
            version '1.2.3'
            artifact <path to file>
        }
    }
}

工件也可以接受存档任务的输出：

'artifact' can also accept output of archive tasks:

publishing {
        publications {
            maven(MavenPublication) {
                groupId 'myGroupId'
                artifactId 'myArtifact'
                version '1.2.3'
                artifact getlibrary
            }
        }
    }

task getlibrary(type:Jar){
    from <directory>
    classifier='lib'
}
