Blade项目打包

Posted by aclyyx on 06-12,2018

简述

Blade的项目打包是使用Maven的package来打包的。
使用【maven-jar-plugin】将项目中的Java文件编译,并打包到jar文件中。
之后,再使用【maven-assembly-plugin】将项目的jar包和依赖包统一打包的dist文件夹中。

源文件

先上一段源文件看看。

pom.xml文件

注意

其中有几处值得注意的地方,下面一一说明。

排除导入Jar的文件

以下源码中,excludes中就是定义的不导入jar文件中的文件。

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-jar-plugin</artifactId>
	<version>3.0.2</version>
	<configuration>
		<archive>
			<manifest>
				<mainClass>net.xxxx.App</mainClass>
				<classpathPrefix>lib/</classpathPrefix>
				<addClasspath>true</addClasspath>
			</manifest>
			<manifestEntries>
				<!-- 在Class-Path下添加配置文件的路径 -->
				<Class-Path>resources/</Class-Path>
			</manifestEntries>
		</archive>
		<excludes>
			<!-- 注意这玩意从编译结果目录开始算目录结构 -->
			<exclude>/app.properties</exclude>
		</excludes>
	</configuration>
</plugin>

插件Assembly配置部分

主要配置信息都定义在了“package.xml”文件中,具体看package.xml源文件。

<plugin>
	<artifactId>maven-assembly-plugin</artifactId>
	<configuration>
		<appendAssemblyId>false</appendAssemblyId>
		<descriptors>
			<descriptor>package.xml</descriptor>
		</descriptors>
		<outputDirectory>${project.build.directory}/dist/</outputDirectory>
	</configuration>
	<executions>
		<execution>
			<id>make-assembly</id>
			<phase>package</phase>
			<goals>
				<goal>single</goal>
			</goals>
		</execution>
	</executions>
</plugin>

执行Maven的导致命令

项目使用的 IDE 是 IDEA ,在 IDEA 中点击【Maven Projects】按照如下图操作和填写,之后点击【Execute】,之后就是等待打包完成啦。
