This is a PR merged from a forked repository. As GitHub hides the original diff on merge, it is displayed below for the sake of provenance: As this is a foreign pull request (from a fork), the diff is supplied below (as it won't show otherwise due to GitHub magic): diff --git a/_posts/cn/2018-04-13-build-java-chassis-microservices-using-gradle.md b/_posts/cn/2018-04-13-build-java-chassis-microservices-using-gradle.md new file mode 100644 index 0000000..90e1219 --- /dev/null +++ b/_posts/cn/2018-04-13-build-java-chassis-microservices-using-gradle.md @@ -0,0 +1,98 @@ +--- +title: "使用gradle构建基于Java Chassis开发的微服务" +lang: cn +ref: build-java-chassis-microservices-using-gradle +permalink: /cn/docs/build-java-chassis-microservices-using-gradle/ +excerpt: "" +last_modified_at: 2018-04-13T09:18:43+08:00 +author: Eric Lee +tags: [gradle] +redirect_from: + - /theme-setup/ +--- + +maven和gradle都是Java世界中常用的构建工具。在[Java Chassis](https://github.com/apache/incubator-servicecomb-java-chassis)项目中采用了maven作为其构建工具，并在maven中心仓库定期发布其最新稳定版。然而，鉴于gradle最新发布版(4.6.0)还不支持maven的统一版本管理(BOM)功能，则在使用gradle构建基于Java Chassis开发的微服务时，需要用到Spring的[依赖管理插件](https://github.com/spring-gradle-plugins/dependency-management-plugin)来引入Java Chassis的版本管理来统一依赖项的版本从而避免产生版本冲突。 + +在maven中，Java Chassis的依赖管理通过以下方式即可引入： + + ```xml + <dependencyManagement> + <dependencies> + <dependency> + <groupId>org.apache.servicecomb</groupId> + <artifactId>java-chassis-dependencies</artifactId> + <version>1.0.0-m1</version> + <type>pom</type> + <scope>import</scope> + </dependency> + </dependencies> + </dependencyManagement> + ``` + +在gradle中，则需要以下三步完成，具体可参考：[https://github.com/apache/incubator-servicecomb-java-chassis/pull/640/files#diff-8d0fdb4970d74d053b6585c3d5ae4cc2R36](https://github.com/apache/incubator-servicecomb-java-chassis/pull/640/files#diff-8d0fdb4970d74d053b6585c3d5ae4cc2R36)。 + +1. 声明使用maven仓库及依赖管理插件的依赖 + + ```gradle + buildscript { + repositories { + mavenLocal() + mavenCentral() + } + dependencies { + classpath('io.spring.gradle:dependency-management-plugin:1.0.4.RELEASE') + } + } + ``` + +2. 启用依赖管理插件 + + ```gradle + apply plugin: 'io.spring.dependency-management' + ``` + +3. 声明Java Chassis的统一依赖管理 + + ```gradle + dependencyManagement { + imports { + mavenBom 'org.apache.servicecomb:java-chassis-dependencies:1.0.0-m1' + } + } + ``` + +**注意：** 在每个子模块中都需要进行上述三步配置。 + +对统一版本管理配置完成后，可增加程序运行入口使得命令行下也能方便的通过gradle运行应用，以便快速验证。其中，可将应用分为Spring Boot应用和非Spring Boot应用来为其添加启动入口： + +1.
