在我的第三个问题之后几乎感觉像是垃圾邮件,因为我的问题看起来很微不足道。但是我在Gradle Docs中找不到任何有关我的案例的帮助,而且有关stackoverflow的其他问题也没有帮助。
这次:我无法在自己的独立自定义插件中使用maven-publish
插件。到目前为止我的插件的代码:
package com.sample.gradle;
import org.gradle.api.Project;
import org.gradle.api.Plugin;
public class SampleGradlePlugin implements Plugin<Project> {
public void apply(Project project) {
project.apply plugin: 'application'
project.apply plugin: 'maven-publish'
project.apply plugin: 'maven'
project.publishing.publications {
maven(MavenPublication) {
groupId project.group
artifactId project.name
version=project.version
from components.java
}
}
project.uploadArchives {
repositories {
mavenDeployer {
repository(url: project.Repo_Upload_Internal){
authentication(userName: project.Repo_Upload_User, password: project.Repo_Upload_Pass)
}
snapshotRepository(url: project.Repo_Upload_Snapshot){
authentication(userName: project.Repo_Upload_User, password: project.Repo_Upload_Pass)
}
}
}
}
//this try/catch is not important for my question
try{
project.repositories {
maven {
url project.Repo_Gp_Internal
credentials {
username project.Repo_Gp_User;
}
}
}
}
catch(MissingPropertyException e){
println "Info: '"+e.getProperty()+"' not declared in \\"+project.name+"\\gradle.properties"
}
}
}
当我在我的一个项目中使用我的插件时,publishing
闭包是带来这个错误的重要部分:
FAILURE: Build failed with an exception.
* Where:
Build file 'C:\Users\quastc\Desktop\Gradle_Projects\Application_RootProject\buil
d.gradle' line: 3
* What went wrong:
A problem occurred evaluating root project 'Application_RootProject'.
> Failed to apply plugin [id 'sample.sample-groovy-plugin']
> Cannot create a Publication named 'MavenPublication' because this container
does not support creating elements by name alone. Please specify which subtype
of Publication to create. Known subtypes are: MavenPublication
我的错误在哪里?我忘记了什么?
如果有人回答,请告诉我你是如何得到你的知识的。
答案 0 :(得分:1)
在我的情况下,我修复了添加此内容的错误消息:
import org.gradle.api.publish.maven.MavenPublication
然后面对其他问题,最后结束使用nebula-publishing-plugin,解决所有问题

这对我有用,gradle 4.10和maven-publish。
在我的自定义插件.groovy中:
import org.gradle.api.publish.maven.MavenPublication
...
project.extensions.configure PublishingExtension, new ClosureBackedAction( {
publications{
mycustompub(MavenPublication) {
groupId = project.group
artifactId = <artifact name>
artifact source: <path to artifact>, extension: 'zip'
}
}})

找到一个适合我的解决方案。我不再使用maven-publish
插件了。只是maven
插件。然后我将这段代码放在我自己的插件的末尾:
project.configurations {
deployerJars
}
project.dependencies {
deployerJars "org.apache.maven.wagon:wagon-http:2.2"
}
project.uploadArchives {
repositories {
mavenDeployer {
repository(url: project.Repo_Upload_Internal){
authentication(userName: project.Repo_Upload_User, password: project.Repo_Upload_Pass)
}
snapshotRepository(url: project.Repo_Upload_Snapshot){
authentication(userName: project.Repo_Upload_User, password: project.Repo_Upload_Pass)
}
}
}
}
此外:
我还没有找到一种方法来抑制zip和tar文件的上传。我仍然需要在几个build.gradle
文件中使用一些复制和粘贴代码来完成这项工作。这是代码:
configurations.archives.with {
artifacts.remove artifacts.find { it.archiveTask.is distZip }
artifacts.remove artifacts.find { it.archiveTask.is distTar }
}
我无法将该代码更改为在我的自定义插件中工作。

传递给project.publishing.publications的闭包在执行时在其上下文中没有project
。这意味着即使您将MavenPublication
应用于maven-plugin
,project
也不在关闭的上下文中。
如果您在构建脚本中编写插件,默认情况下它将具有project
作为上下文,但在将其作为独立插件编写时,上下文会有所不同。
您可以setDelegate(project)
在闭包上设置上下文,然后传递它:
def publicationsClosure = {
maven(MavenPublication) {
groupId project.group
artifactId project.name
version=project.version
from components.java
}
}
publicationsClosure.setDelegate(project)
project.publishing.publications(publicationsClosure)
我在插件中遇到了同样的错误,并最终意识到我在阅读本文时发生了什么:http://trickyandroid.com/gradle-tip-2-understanding-syntax/
