在gradle中将pom.xml包含在Jar中

问题描述

我试图在使用gradle创建的jar中包含生成的pom.xml.

I'm attempting to include a generated pom.xml in the jar that I'm creating with gradle.

到目前为止，在我的父项目中，我有

So far, in my parent project, I have

subprojects {
    apply plugin: 'maven-publish'

    publishing {
        publications {
            maven(MavenPublication) {
                from(components.java)
            }
        }
    }
}

在子项目中，我有:

tasks.build.dependsOn install

sourceSets {
    main {
        resources {
            srcDirs = [ "src/main/resources", "build/poms" ]
        }
    }
}

这将生成./build/poms/pom-default.xml，但不会将其添加到JAR中.

This will generate ./build/poms/pom-default.xml, but it will not add it to the JAR.

在比build更早的阶段创建依赖关系会创建循环依赖关系(而且我也不知道这是否是问题所在).

Creating a dependency on an earlier phase than build creates circular dependencies (and I don't know whether this is the problem anyway).

此外，我希望pom.xml出现在名称为pom.xml(而不是pom-default.xml)的META-INF内部，因此无论如何这都不是正确的方法.

Also, I'd like the pom.xml to show up inside META-INF with name pom.xml (not pom-default.xml), so this may not be the right approach anyway.

以某种方式，我认为它不可能像看起来那样复杂?

Somehow I'm thinking it can't be as complicated as this looks?

推荐答案

通过将以下内容添加到您的subprojects闭包中，您应该能够在您的JAR中包含POM:

You should be able to include the POM in your JAR by adding the following to your subprojects closure:

jar {
    into('META-INF') {
        from generatePomFileForMavenPublication
        rename { it.replace('pom-default.xml', 'pom.xml') }
    }
}

如果您已经有jar闭包，则可以在其中添加它.这会自动在 generatePomFileForMavenPublication 任务上创建任务依赖项，以便在创建JAR时存在POM文件.
不需要您问题中的sourceSets部分.

If you already have a jar closure, you can add it there. This automatically creates a task dependency on the generatePomFileForMavenPublication task, so that the POM file is there when the JAR is created.
The sourceSets part from your question would not be required for this.

(附带说明:完全没有必要这样做，因为Maven发布过程会将POM作为单独的工件发布.)

(Side note: It would not be strictly necessary to do this at all, because the Maven publish process will publish the POM as an individual artifact anyway.)
