我想从将通过maven-publish
插件发布的 RuleSource 内部创建一个 Maven 发布。发布的工件是从规则创建的一系列 Zip 任务的输出。当我尝试添加工件时,我得到一个循环规则异常。
这是我的非常简单的build.gradle
:
buildscript {
repositories {
mavenCentral()
}
dependencies {
}
}
task wrapper(type: Wrapper) {
gradleVersion = '3.3'
}
apply plugin: 'groovy'
apply plugin: 'testpub'
repositories {
mavenCentral()
}
dependencies {
compile 'org.codehaus.groovy:groovy-all:2.4.7'
}
该testpub
插件存在于buildSrc
目录中。为了能够像上面那样应用它,它需要以下属性文件:
// buildSrc/src/main/resources/META_INF/gradle-plugins/testpub.properties
implementation-class=TestPubPlugin
这是一个非常简单的插件文件:
import org.gradle.api.Project
import org.gradle.api.Plugin
import org.gradle.model.RuleSource
import org.gradle.api.Task
import org.gradle.model.Mutate
import org.gradle.model.Finalize
import org.gradle.api.tasks.bundling.Zip
import org.gradle.model.ModelMap
import org.gradle.api.publish.PublishingExtension
import org.gradle.api.publish.maven.MavenPublication
class TestPubPlugin implements Plugin<Project> {
void apply(Project project) {
project.configure(project) {
apply plugin: 'maven-publish'
publishing {
repositories {
maven {
url "someUrl"
}
}
}
}
}
static class TestPubPluginRules extends RuleSource {
@Mutate
public void createSomeTasks(final ModelMap<Task> tasks) {
5.times { suffix ->
tasks.create("someTask${suffix}", Zip) {
from "src"
destinationDir(new File("build"))
baseName "someZip${suffix}"
}
}
}
@Mutate
public void configurePublishingPublications(final PublishingExtension publishing, final ModelMap<Task> tasks) {
// Intention is to create a single publication whose artifacts are formed by the `someTaskx` tasks
// where x = [0..4]
publishing {
publications {
mavPub(MavenPublication) {
tasks.matching {it.name.startsWith('someTask')}.each { task ->
artifact(task)
}
}
}
}
}
}
}
该插件创建了许多名为someTaskx
where的任务x=[0..4]
。他们只是压缩了 src 目录。我想将输出文件作为工件添加到单个 MavenPublication。但是,我得到以下异常:
* What went wrong:
A problem occurred configuring root project 'testpub'.
> A cycle has been detected in model rule dependencies. References forming the cycle:
tasks
\- TestPubPlugin.TestPubPluginRules#createSomeTasks(ModelMap<Task>)
\- MavenPublishPlugin.Rules#realizePublishingTasks(ModelMap<Task>, PublishingExtension, File)
\- PublishingPlugin.Rules#tasksDependOnProjectPublicationRegistry(ModelMap<Task>, ProjectPublicationRegistry)
\- projectPublicationRegistry
\- PublishingPlugin.Rules#addConfiguredPublicationsToProjectPublicationRegistry(ProjectPublicationRegistry, PublishingExtension, ProjectIdentifier)
\- publishing
\- TestPubPlugin.TestPubPluginRules#configurePublishingPublications(PublishingExtension, ModelMap<Task>)
\- tasks
出了什么问题,我该如何解决?
