1.新建Gradle项目：
2.建立src/main/groovy目录，并添加如下代码：
ConfigPlugin.groovy package com.wemall.config import org.gradle.api.Plugin
import org.gradle.api.Project class ConfigPlugin implements Plugin<Project> { void apply(Project project) {
project.extensions.create("configPluginExtension", ConfigPluginExtension)
project.task("configTask", type: ConfigTask)
}
}
ConfigTask.groovy
package com.wemall.config import org.gradle.api.DefaultTask
import org.gradle.api.tasks.TaskAction import groovy.swing.impl.DefaultAction
import groovy.xml.Namespace
import groovy.xml.StreamingDOMBuilder class ConfigTask extends DefaultTask { static final String CONFIG_CENTER_URL = "http://192.168.127.137:8080/config-center-0.0.1-SNAPSHOT/"; @TaskAction
void download() { def names = project.configPluginExtension.name;
def version = project.configPluginExtension.version; names.each { name -> def inputStream = new URL(CONFIG_CENTER_URL + name).openStream(); println ("${project.projectDir} , ${project.buildDir}, ${project.rootDir}, ${project.resources}"); def file = new File("${project.projectDir}/src/main/resources/${name}");
file.withOutputStream {
outputStream ->
outputStream << inputStream;
}
}
} }
ConfigPluginExtension.groovy
package com.wemall.config
class ConfigPluginExtension {
def name = [];
def version = "";
}
3.在src/main/resources下建立MEAT-INFO/gradle-plugins目录，并添加com.wemall.config.properties配置文件
com.wemall.config.properties内容,这个properties文件的名称，就为自定义Gradle插件名称. implementation-class=com.wemall.config.ConfigPlugin
4.build.gradle文件内容:
apply plugin: 'groovy'
apply plugin: 'maven'
apply plugin: 'maven-publish' dependencies {
compile gradleApi()
compile localGroovy()
} group='com.wemall.config'
version='1.0.7-SNAPSHOT' publishing {
publications {
maven(MavenPublication) {
groupId project.group
artifactId project.name
version project.version
//若是war包，就写components.web,若是jar包，就写components.java
from components.java
}
}
repositories {
maven { if (project.version.endsWith('-SNAPSHOT')) {
url = "http://192.168.184.155:8081/repository/maven-snapshots/"
} else {
url = "http://192.168.184.155:8081/repository/maven-releases/"
} credentials {
username 'admin'
password 'admin123'
}
}
}
}
5.发布接入到nexus仓库中:
6.其他gradle项目引入插件：
buildscript {
repositories {
maven {
url 'http://192.168.184.155:8081/repository/maven-public/'
}
}
dependencies {
classpath group: 'com.wemall.config',name: 'config-plugin',version: '1.0.7-SNAPSHOT'
}
}
plugins {
id 'java-library'
}
apply plugin: 'com.wemall.config'
dependencies {
testImplementation 'junit:junit:4.12'
}
configPluginExtension {
name = ["a.properties", "b.properties", "c.properties"]
version = "1.0.0-SNAPSHOT"
}
7.在引入插件的项目中运行插件:
gradlew -q configTask
此时configTask插件就可以连接到网址的配置中上下载配置文件。configTask名称为ConfigPlugin.groovy文件中的project.task("configTask", type: ConfigTask)字符串名称。
