使用maven快速生成打包文件2

news 来源：原创 2024/9/20 19:53:50

前面介绍了使用Maven打包基于SpringBoot开发的微服务，打出的JAR包包含所有的依赖，因此一般包比较大，可能会有几百M，但是有时候在调试阶段，经常需要更新程序，每更新一次就要上传几百M的JAR包，特别不方便，因此这里提供一种方法将依赖的JAR包统一放到lib目录中，这样打出的微服务包就很小了，更新起来也方便很多。先上pom.xml文件

<?xml version="1.0" encoding="UTF-8"?>

</project>

这里只介绍一下不同的部分，相同的部分，参看前面一篇

<plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-dependency-plugin</artifactId><executions><execution><id>copy-dependencies</id><phase>prepare-package</phase><goals><goal>copy-dependencies</goal></goals><configuration><outputDirectory>${project.build.directory}/roma/lib</outputDirectory><overWriteReleases>false</overWriteReleases><overWriteSnapshots>false</overWriteSnapshots><overWriteIfNewer>true</overWriteIfNewer><includeScope>compile</includeScope><excludeScope>test</excludeScope><excludeArtifactIds>junit-jupiter,junit-jupiter-api,junit-jupiter-engine,junit-jupiter-params,junit-platform-commons,junit-platform-engine</excludeArtifactIds></configuration></execution></executions>
</plugin>

maven-dependency-plugin插件将项目的依赖库复制到一个指定的目录中，指定的目录配置到outputDirectory即可。excludeScope表示将test的依赖排除掉，也可以在excludeArtifactIds中指定特定的依赖。
然后编译打包的时候，只需执行maven clean package即可。
