maven - Gradle 不会将 jar 复制到 Maven .m2 文件夹

Question

此 build.gradle 文件中可能缺少什么阻止 publishToMavenLocal 不将文件复制到 .m2 文件夹？

该脚本确实有“maven-publish”插件。

您的构建没有配置任何发布，因此 publishToMavenLocal 任务是一个 noop:

$ ./gradlew --console=verbose publishToMavenLocal
> Task :publishToMavenLocal UP-TO-DATE

BUILD SUCCESSFUL in 0s

当您像本例一样配置发布时......

task buildMyArtifact(type: Zip) {
    // TODO using the build script as a sample file here; use whatever makes
    //   sense for your project
    from 'build.gradle'
    archiveBaseName = 'whateverNameInBuildDir'
    destinationDirectory = buildDir
}

publishing {
    publications {
        myPublication(MavenPublication) {
            artifact buildMyArtifact
            groupId 'com.example'
            artifactId 'my-module'
            version '1.0.0'
        }
    }
}

... 然后 publishToMavenLocal 任务将发布安装到本地 Maven 存储库中:

$ ./gradlew --console=verbose publishToMavenLocal
> Task :buildMyArtifact
> Task :generatePomFileForMyPublicationPublication
> Task :publishMyPublicationPublicationToMavenLocal
> Task :publishToMavenLocal
